Characterizing the Relationship Between Volatile Organic Compounds and Air Pollutants via Exposure Pathways Originating from Emission Sources in Large Industrial Cities

Air pollution (NO2, SO2, PM2.5) emissions by pollutant source (point, line, surface) and substance (NOx, SOx, PM2.5, NH3, VOC) for data on emissions and emissions from small businesses in Korea. , O3, NH3), we would like to analyze the contribution of the impact on the surrounding area. Development of algorithm technology optimized for decision-making based on evaluation of environmental pollutants. Methods: Establishment of emission source inventory through air pollution emission survey, and subsequent emission source measurement data through emission status survey and establishment of VOC and PM profile using EPA and Speciate, etc., application of questionnaire and comparative analysis (measurement analysis) according to the emission characteristics of the business site. result). As a result of building an inventory of air pollutant emission sources centered on 190 workplaces, the characteristics of emission sources through the final 104 workplaces were confirmed, and the results of the air pollutant emission status showed the national air pollutant emissions by substance (CO, NOx, SOx, TSP, PM10, PM2.5, VOC, NH3) were confirmed. This is data applied to the results of VOC and PM profile construction using EPA and Speciate5.1, and consistent characteristics of pollution concentration were confirmed around five business sites and four representative spaces in the surrounding area. It is recommended that the questionnaire be used as basic data to identify the concentration level of pollutants (chemical species) by emission source according to the source profile of domestic environmental pollutants.
