This study was done to see how water that has been treated and has magnets in it affects soil using three different kinds of irrigation treatments; including "wastewater", "magnetic wastewater" and "normal water", and four times to make sure the results were accurate. Soil samples collected from two layers of soil, one near the surface and one deeper down, and from the top and bottom of each furrow. The findings showed that the treatments did not have much of a difference in soil EC levels. However, the treatment with magnetized wastewater caused a lot of changes in salinity levels in the lower layers of soil. This is probably because the salt in the wastewater can move easily and build up in the soil underground. The pH of the soil changed because of the wastewater and became lower. However, making the wastewater magnetic did not have a significant impact on the pH of the soil. Magnetized Wastewater Normal Water Irrigation Treatments EC Levels pH Soil Samples Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Introduction In dry places like Iran, using strategies to use unusual water sources like waste water from industry, cities, and farming can help make up for the lack of water. It can also stop the bad things that happen when we let waste water into the environment (1). The ongoing need for water in non-arid areas has also increased the necessity to use wastewater as a cost-effective resource in planning (2). Using wastewater for irrigation can either be helpful or harmful, depending on the region, how it is used, and its quality. Research shows that using wastewater and sewage sludge can make the top layer of soil less dense in many situations (3). Wastewater and sewage sludge can help soil hold more water because they contain organic materials (4). Studies show that using different types of water can affect the chemical properties of soil in specific ways. According to the results, using wastewater on soil makes it salty. In these conditions, we expect the waste water to be saltier than water that hasn't been treated. For instance, when we studied the impact of wastewater and drinking water with salt levels of 1.05 and 0.6 d/m on silt loam soil, we found that the soil became more salty (ECe) compared to when only drinking water was used (5). Additionally, watering the soil with city wastewater and well water for 6 months each day showed that the city wastewater made the soil very salty at different levels (6). The problem of too much salt in the soil from untreated sewage has also been reported (7). Meanwhile, on the farm during the growing season, the impact of wastewater on soil saltiness can change because of the plants. This depends on whether there are plants growing or not. For instance, a study was done in a dry area to see how using drip irrigation with wastewater would affect different types of soil over three years. They also planted olive trees, corn, spinach, and potatoes to see how they would grow. The study found that wastewater doesn't have much of an effect on soil salinity (3). The findings of a similar project also found that when colza plants are present and furrow irrigation is used, the soil's saltiness increases slightly when irrigated with household wastewater compared to well water (8). Different studies have shown different results when it comes to the pH of the soil after wastewater is used. Some studies have even shown results that contradict each other. A) Some research shows that using treated wastewater, raw sewage, and its sludge on the soil has made the soil more acidic. For instance, a 10-year study found that watering sandy soil with wastewater and non-wastewater changed the soil's acidity. The soil's pH dropped by 1.76 units when wastewater was used, possibly due to organic acids in the wastewater (9). In another study, 100 hectares of land growing wheat were watered for 29 years using wastewater. The study found that wastewater has made the soil more acidic at different levels underground (8). A study found that using wastewater for irrigation can make the soil more acidic. This is because the wastewater has a lower pH than drinking water (9). B) Sometimes, using wastewater to water plants has made the soil more acidic. For instance, in a research study, when they compared using city wastewater and well water for irrigation, they found that the pH level of the soil was 7.63 with wastewater and 7.2 with well water. This means the soil irrigated with wastewater had a higher pH level than the soil irrigated with well water at all depths (4). Some studies have found that soil pH has gone up because of high alkalinity, salt concentration, and the high pH of the wastewater (7). Some studies have found that using wastewater doesn't have much of an effect (2). Meanwhile, people are debating whether magnetism can help improve the quality of water. Studies have found that "magnetism" can also reduce saltiness in soil (6). Some studies have shown that magnetized water has not had much effect on soil pH (4). Magnetic water Magnetic force can change water into a liquid with special effects on its properties, like how it dissolves other substances and its temperature, weight, and ability to conduct electricity. (2). By using magnetic power, the water molecules become smaller and can seep into the soil more quickly. In simple words, water flows more easily, feels wetter, and sticks to soil particles, preventing them from sinking into the soil. Therefore, the soil can hold more water. By changing the water, even gypsum, which usually doesn't dissolve in hard water, can dissolve in magnetic water. This helps water soak into the soil when mixed with sodium. This process helps to form clusters of soil particles, which increase the soil's fertility, ability to grow plants, and ability to allow air and water to flow through the soil (7). We tested using magnets to help plants grow better and saw different results. For instance, studies have found that water with magnets in it made more cucumber flowers and increased the amount of cucumber produced (by about 10%) (10), but when they did an experiment in Yazd at the Agricultural Research Center, they didn't see any big changes in the crop they were studying (3). The use of magnetized water did not make a big difference in the amount of corn seeds, the weight of a thousand grains, or the number of grains on each cob in the studies at the Khuzestan Center of Agricultural Research. However, using magnetism to water tomato plants in a greenhouse using drip irrigation led to more tomatoes growing on the plants (9). It appears that the quality and amount of water, the saltiness of the soil, the type of plant, and how long the plant drinks magnetized water can all affect how well magnets work on the plants. " Reports show that using magnets could help with the problems in agriculture caused by less water and having to use different types of water. It could make wastewater less harmful. Another study that is missing from scientific reports is about the problems with surface irrigation and using non-traditional water sources. This study also looks at the effects of combining this with magnetism. This study looked at how changes in city wastewater might affect the saltiness and acidity of soil when it's watered through furrows, and how a magnetic field might influence this. Materials and Methods This study was done at the Chah-Anari farm at Isfahan University of Technology. The study used three types of water: regular water, water from the sewage treatment pool, and water from the sewage treatment pool that had been exposed to a magnetic field. The tests were done in a randomized way and were repeated four times. Table 1 shows some details about the soil on the farm. To water 12 furrows, gated pipes were used. Each gate needed 0.8 l/s of water per second based on the slope of the ground and the type of soil, so that it wouldn't cause erosion. The research lasted about two months, and each furrow was irrigated five times, for a total of 60 irrigations. Wastewater was collected from the furrows after the first, third, and fifth times we watered the soil. Wastewater was collected from two different depths: the top layer (0–15 cm) and the bottom layer (15–40 cm), and also collected at two different distances from the start of the furrows: 9–12 meters and 27–30 meters away. Altogether, at 72 examples. Soil samples were placed in plastic bags and sent to the laboratory. Then, the samples were dried in the oven. Then they were smashed with a metal hammer and filtered through a 2mm sieve. In this way, soil-immersed mud was arranged, and the extricate of immersed mud for each test was obtained utilizing a suction pump and channel paper (Fig. 1). The two planned chemical properties were evaluated using the pH meter and the Ec-meter (1). We looked at regular water, dirty water, and water that had been magnetized at the start, middle, and end of the study. Physical things were checked like how much stuff is floating in the water, chemical things like how acidic or basic it is, and biological things like how much oxygen bacteria need to live and how many harmful bacteria are in the water. The quality of the water is shown in Table 2. It has been noticed that the non-wastewater is of good quality and can be used for irrigation as usual. When it comes to wastewater, everything is suitable for using it to water crops except for the amount of coliforms. The magnetic field doesn't seem to have much of an effect on the quality of the wastewater. The number of positive and negative ions doesn't change much after passing through the magnetic field. Additionally, the levels of BOD5 and COD in wastewater have been within the allowed limits, but a small change has been noticed in them when they are exposed to a magnetic field. This means that the amount of bacteria in some tests went up a lot, and in two out of three tests, the amount of bacteria increased a lot. Results and Discussion Before looking at the results, there are some important problems to talk about. Explanation 1 Instead of looking at the exact numbers, a first look at the data showed that because things changed during the project, just comparing the final numbers could give the wrong idea. In this research, it's more important to look at how the soil changes after being watered multiple times than to just focus on the exact numbers. So, results were showed at how much the data changed compared to the first watering. Importance of the probability level: There are many reasons why the results of this research are not very accurate. The soil has a lot of gravel, is uneven and different across the farm, and is light and dry. These factors make it more likely that the results have errors and are not reliable. So, the report uses the numbers that show the smallest level of importance in the analysis. The p values are better at showing how significant something is and what it means compared to using the usual five or ten percent levels. It's important to remember that values lower than five or one percent shows a big difference in the data. In simpler terms, this means that in these situations, there is a very high chance that there is a real difference between the data, around 95–99%. The real chance of something happening by using the p value was found. Outliers are data points that are significantly different from the other data. They are usually located far away from the middle of the data and can affect statistical analysis. Numbers that are far from the middle of a set of numbers are not considered. In this study, to make sure the statistical analysis was accurate, left out a small amount of data that didn't fit with the rest. Then the statistical analysis was done again with the remaining data. Impact of dirty water and magnetized dirty water on the soil's saturated extract (EC e ) Figure 2 shows the amount of salt in the soil from different water treatments and how much it changed. It can be seen that after watering the soil with water and wastewater five times, the saltiness of the soil at the top has gone down. This is different from what happened when the soil with just regular water and wastewater was watered, where the saltiness increased. This difference is related to the different furrows in the soil. This happens because the water has a little bit of salt in it, and the soil is always washed with this salty water. In the soil underground, there is also a similar pattern, but the level of salt in the water after the second irrigation has gone up a lot compared to the first time. This increase is probably because the water can carry more minerals when it is magnetized, and the minerals are collecting deeper in the soil. The table shows the statistical analysis of the results in terms of how they have changed. It appears that there isn't a big difference between the treatments on the top layer. But when were removes some unusual data from the treatments in the lower layer, a difference of about 5% was seen. It's important to note that if treatments don't show a noticeable difference, it doesn't mean they don't affect soil salinity. Looking closely at the results, there are big differences between treatments in different areas, which make it harder to see if the differences are significant. For this reason, treatments were compared using a test called "the least significant differences test" (see table 3). Researching these results shows that the amount of salt in the topsoil is significantly different when using magnetized wastewater compared to regular water treatment, by almost 5%. In the underground layer, there is a significant difference in the saltiness between magnetized wastewater and regular wastewater, as well as between magnetized wastewater treatment and water, at a level close to 5%. This discovery shows that there is a big difference between the treatments mentioned above. In any case, the data changes in various test trials were looked (Fig. 3). The average amount of salt in the top and subsurface soil is going down because of irrigation with water and wastewater. Magnetism is slowing down this decrease in the top layer but making it go up in the subsurface layer. The acidity-alkalinity level of soil in medications and diverse parts of the water system has been displayed in Fig. 4 as a crude figure and as relative changes in Fig. 5. It seems that wastewater with a pH level of 7.84 and magnetized wastewater with a pH level of 7.88 have caused a small decrease in the soil but an increase in water treatment with a pH level of 7.6 during the season. The water's acidity or alkalinity level is 7.6, and it's hard to change this in the soil. This might be because of the chemical reaction of the soil solution, which wasn't studied in this project. The tables 4, 5, and 6 show the statistical analysis of these results as relative changes. Treating soil with sewage water has caused some big changes in its chemical makeup. In any case, the difference has been because of the sewage effect, and putting magnets in the wastewater hasn't had much of an effect. This thing that happens underground has always had less liquid moving through it. But now, it's changing a little because of wastewater and magnetism. Conclusions Usually, the "soil salinity" level goes down by about 40% after 5 times of watering with water and wastewater compared to the first time of watering. Using magnetized wastewater for irrigation caused the salt levels in the soil to increase a lot. This rise may be connected to the water with magnets. Studies have shown that using treated wastewater has caused a small decrease in soil acidity over the course of the season. The soil reacted slightly when it was watered. In any case, the difference is mostly because of the sewage chemicals, and using magnets on the wastewater hasn't made much of a difference.

using strategies to use unusual water sources like waste water from industry, cities, and farming can help make up for the lack of water. It can also stop the bad things that happen when we let waste water into the environment (1). The ongoing need for water in non-arid areas has also increased the necessity to use wastewater as a cost-effective resource in planning (2). Using wastewater for irrigation can either be helpful or harmful, depending on the region, how it is used, and its quality. Research shows that using wastewater and sewage sludge can make the top layer of soil less dense in many situations (3). Wastewater and sewage sludge can help soil hold more water because they contain organic materials (4). Studies show that using different types of water can affect the chemical properties of soil in specific ways. According to the results, using wastewater on soil makes it salty. In these conditions, we expect the waste water to be saltier than water that hasn't been treated. For instance, when we studied the impact of wastewater and drinking water with salt levels of 1.05 and 0.6 d/m on silt loam soil, we found that the soil became more salty (ECe) compared to when only drinking water was used (5). Additionally, watering the soil with city wastewater and well water for 6 months each day showed that the city wastewater made the soil very salty at different levels (6). The problem of too much salt in the soil from untreated sewage has also been reported (7). Meanwhile, on the farm during the growing season, the impact of wastewater on soil saltiness can change because of the plants. This depends on whether there are plants growing or not. For instance, a study was done in a dry area to see how using drip irrigation with wastewater would affect different types of soil over three years. They also planted olive trees, corn, spinach, and potatoes to see how they would grow. The study found that wastewater doesn't have much of an effect on soil salinity (3). The findings of a similar project also found that when colza plants are present and furrow irrigation is used, the soil's saltiness increases slightly when irrigated with household wastewater compared to well water (8). Different studies have shown different results when it comes to the pH of the soil after wastewater is used. Some studies have even shown results that contradict each other. A) Some research shows that using treated wastewater, raw sewage, and its sludge on the soil has made the soil more acidic. For instance, a 10-year study found that watering sandy soil with wastewater and non-wastewater changed the soil's acidity. The soil's pH dropped by 1.76 units when wastewater was used, possibly due to organic acids in the wastewater (9). In another study, 100 hectares of land growing wheat were watered for 29 years using wastewater. The study found that wastewater has made the soil more acidic at different levels underground (8). A study found that using wastewater for irrigation can make the soil more acidic. This is because the wastewater has a lower pH than drinking water (9). B) Sometimes, using wastewater to water plants has made the soil more acidic. For instance, in a research study, when they compared using city wastewater and well water for irrigation, they found that the pH level of the soil was 7.63 with wastewater and 7.2 with well water. This means the soil irrigated with wastewater had a higher pH level than the soil irrigated with well water at all depths (4). Some studies have found that soil pH has gone up because of high alkalinity, salt concentration, and the high pH of the wastewater (7). Some studies have found that using wastewater doesn't have much of an effect (2). Meanwhile, people are debating whether magnetism can help improve the quality of water. Studies have found that \"magnetism\" can also reduce saltiness in soil (6). Some studies have shown that magnetized water has not had much effect on soil pH (4).\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMagnetic water\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eMagnetic force can change water into a liquid with special effects on its properties, like how it dissolves other substances and its temperature, weight, and ability to conduct electricity. (2). By using magnetic power, the water molecules become smaller and can seep into the soil more quickly. In simple words, water flows more easily, feels wetter, and sticks to soil particles, preventing them from sinking into the soil. Therefore, the soil can hold more water. By changing the water, even gypsum, which usually doesn't dissolve in hard water, can dissolve in magnetic water. This helps water soak into the soil when mixed with sodium. This process helps to form clusters of soil particles, which increase the soil's fertility, ability to grow plants, and ability to allow air and water to flow through the soil (7). We tested using magnets to help plants grow better and saw different results. For instance, studies have found that water with magnets in it made more cucumber flowers and increased the amount of cucumber produced (by about 10%) (10), but when they did an experiment in Yazd at the Agricultural Research Center, they didn't see any big changes in the crop they were studying (3). The use of magnetized water did not make a big difference in the amount of corn seeds, the weight of a thousand grains, or the number of grains on each cob in the studies at the Khuzestan Center of Agricultural Research. However, using magnetism to water tomato plants in a greenhouse using drip irrigation led to more tomatoes growing on the plants (9). It appears that the quality and amount of water, the saltiness of the soil, the type of plant, and how long the plant drinks magnetized water can all affect how well magnets work on the plants. \" Reports show that using magnets could help with the problems in agriculture caused by less water and having to use different types of water. It could make wastewater less harmful. Another study that is missing from scientific reports is about the problems with surface irrigation and using non-traditional water sources. This study also looks at the effects of combining this with magnetism. This study looked at how changes in city wastewater might affect the saltiness and acidity of soil when it's watered through furrows, and how a magnetic field might influence this.\u003c/p\u003e"},{"header":"Materials and Methods","content":"\u003cp\u003eThis study was done at the Chah-Anari farm at Isfahan University of Technology. The study used three types of water: regular water, water from the sewage treatment pool, and water from the sewage treatment pool that had been exposed to a magnetic field. The tests were done in a randomized way and were repeated four times. Table 1 shows some details about the soil on the farm. To water 12 furrows, gated pipes were used. Each gate needed 0.8 l/s of water per second based on the slope of the ground and the type of soil, so that it wouldn\u0026apos;t cause erosion. The research lasted about two months, and each furrow was irrigated five times, for a total of 60 irrigations. Wastewater was collected from the furrows after the first, third, and fifth times we watered the soil. Wastewater was collected from two different depths: the top layer (0\u0026ndash;15 cm) and the bottom layer (15\u0026ndash;40 cm), and also collected at two different distances from the start of the furrows: 9\u0026ndash;12 meters and 27\u0026ndash;30 meters away. Altogether, at 72 examples. Soil samples were placed in plastic bags and sent to the laboratory. Then, the samples were dried in the oven. Then they were smashed with a metal hammer and filtered through a 2mm sieve. In this way, soil-immersed mud was arranged, and the extricate of immersed mud for each test was obtained utilizing a suction pump and channel paper (Fig. 1). The two planned chemical properties were evaluated using the pH meter and the Ec-meter (1). We looked at regular water, dirty water, and water that had been magnetized at the start, middle, and end of the study. \u0026nbsp;Physical things were checked like how much stuff is floating in the water, chemical things like how acidic or basic it is, and biological things like how much oxygen bacteria need to live and how many harmful bacteria are in the water. The quality of the water is shown in Table 2. It has been noticed that the non-wastewater is of good quality and can be used for irrigation as usual. When it comes to wastewater, everything is suitable for using it to water crops except for the amount of coliforms. The magnetic field doesn\u0026apos;t seem to have much of an effect on the quality of the wastewater. The number of positive and negative ions doesn\u0026apos;t change much after passing through the magnetic field. Additionally, the levels of BOD5 and COD in wastewater have been within the allowed limits, but a small change has been noticed in them when they are exposed to a magnetic field. This means that the amount of bacteria in some tests went up a lot, and in two out of three tests, the amount of bacteria increased a lot.\u003c/p\u003e"},{"header":"Results and Discussion","content":"\u003cp\u003eBefore looking at the results, there are some important problems to talk about. Explanation 1 Instead of looking at the exact numbers, a first look at the data showed that because things changed during the project, just comparing the final numbers could give the wrong idea. In this research, it\u0026apos;s more important to look at how the soil changes after being watered multiple times than to just focus on the exact numbers. So, results were showed at how much the data changed compared to the first watering. Importance of the probability level: There are many reasons why the results of this research are not very accurate. The soil has a lot of gravel, is uneven and different across the farm, and is light and dry. These factors make it more likely that the results have errors and are not reliable. So, the report uses the numbers that show the smallest level of importance in the analysis. The p values are better at showing how significant something is and what it means compared to using the usual five or ten percent levels. It\u0026apos;s important to remember that values lower than five or one percent shows a big difference in the data. In simpler terms, this means that in these situations, there is a very high chance that there is a real difference between the data, around 95\u0026ndash;99%. The real chance of something happening by using the p value was found. Outliers are data points that are significantly different from the other data. They are usually located far away from the middle of the data and can affect statistical analysis. Numbers that are far from the middle of a set of numbers are not considered. In this study, to make sure the statistical analysis was accurate, left out a small amount of data that didn\u0026apos;t fit with the rest. Then the statistical analysis was done again with the remaining data. Impact of dirty water and magnetized dirty water on the soil\u0026apos;s saturated extract (EC\u003csub\u003ee\u003c/sub\u003e) Figure 2 shows the amount of salt in the soil from different water treatments and how much it changed. It can be seen that after watering the soil with water and wastewater five times, the saltiness of the soil at the top has gone down. This is different from what happened when the soil with just regular water and wastewater was watered, where the saltiness increased. This difference is related to the different furrows in the soil. This happens because the water has a little bit of salt in it, and the soil is always washed with this salty water. In the soil underground, there is also a similar pattern, but the level of salt in the water after the second irrigation has gone up a lot compared to the first time. This increase is probably because the water can carry more minerals when it is magnetized, and the minerals are collecting deeper in the soil. The table shows the statistical analysis of the results in terms of how they have changed. It appears that there isn\u0026apos;t a big difference between the treatments on the top layer. But when were removes some unusual data from the treatments in the lower layer, a difference of about 5% was seen. It\u0026apos;s important to note that if treatments don\u0026apos;t show a noticeable difference, it doesn\u0026apos;t mean they don\u0026apos;t affect soil salinity. Looking closely at the results, there are big differences between treatments in different areas, which make it harder to see if the differences are significant. For this reason, treatments were compared using a test called \u0026quot;the least significant differences test\u0026quot; (see table 3). Researching these results shows that the amount of salt in the topsoil is significantly different when using magnetized wastewater compared to regular water treatment, by almost 5%. In the underground layer, there is a significant difference in the saltiness between magnetized wastewater and regular wastewater, as well as between magnetized wastewater treatment and water, at a level close to 5%. This discovery shows that there is a big difference between the treatments mentioned above. In any case, the data changes in various test trials were looked (Fig. 3). The average amount of salt in the top and subsurface soil is going down because of irrigation with water and wastewater. Magnetism is slowing down this decrease in the top layer but making it go up in the subsurface layer. The acidity-alkalinity level of soil in medications and diverse parts of the water system has been displayed in Fig. 4 as a crude figure and as relative changes in Fig. 5. It seems that wastewater with a pH level of 7.84 and magnetized wastewater with a pH level of 7.88 have caused a small decrease in the soil but an increase in water treatment with a pH level of 7.6 during the season. The water\u0026apos;s acidity or alkalinity level is 7.6, and it\u0026apos;s hard to change this in the soil. This might be because of the chemical reaction of the soil solution, which wasn\u0026apos;t studied in this project. The tables 4, 5, and 6 show the statistical analysis of these results as relative changes. Treating soil with sewage water has caused some big changes in its chemical makeup. In any case, the difference has been because of the sewage effect, and putting magnets in the wastewater hasn\u0026apos;t had much of an effect. This thing that happens underground has always had less liquid moving through it. But now, it\u0026apos;s changing a little because of wastewater and magnetism.\u003c/p\u003e"},{"header":"Conclusions","content":"\u003cp\u003eUsually, the \"soil salinity\" level goes down by about 40% after 5 times of watering with water and wastewater compared to the first time of watering. Using magnetized wastewater for irrigation caused the salt levels in the soil to increase a lot. This rise may be connected to the water with magnets. Studies have shown that using treated wastewater has caused a small decrease in soil acidity over the course of the season. The soil reacted slightly when it was watered. In any case, the difference is mostly because of the sewage chemicals, and using magnets on the wastewater hasn't made much of a difference.\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eData Availability Statement\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eData will be made available on reasonable request.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConflict of Interest\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThere is no conflict of interest.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompliance with Ethical Standards\u0026nbsp;\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eConflicts of interest author have declared that he have no conflicts of interest.

This study was done to see how water that has been treated and has magnets in it affects soil using three different kinds of irrigation treatments; including \"wastewater\", \"magnetic wastewater\" and \"normal water\", and four times to make sure the results were accurate. Soil samples collected from two layers of soil, one near the surface and one deeper down, and from the top and bottom of each furrow. The findings showed that the treatments did not have much of a difference in soil EC levels. However, the treatment with magnetized wastewater caused a lot of changes in salinity levels in the lower layers of soil. This is probably because the salt in the wastewater can move easily and build up in the soil underground. The pH of the soil changed because of the wastewater and became lower. However, making the wastewater magnetic did not have a significant impact on the pH of the soil.","manuscriptTitle":"Effects of magnetized wastewater on chemical properties of soil","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-11-06 08:32:37","doi":"10.21203/rs.3.rs-5766260/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"aeb267b4-ed40-48f6-8683-e22755df1a12","owner":[],"postedDate":"November 6th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2025-11-06T08:32:37+00:00","versionOfRecord":[],"versionCreatedAt":"2025-11-06 08:32:37","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-5766260","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-5766260","identity":"rs-5766260","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
