Toxicity of heavy metals in water, sediments and different body organs of fish Labeo rohita (rohu) at head Balloki, river Ravi, Lahore Pakistan

The present work was designed to evaluate the Contamination of heavy metals in water is regarded as global crises with a large share in developing countries like Pakistan. In present study, health risk consequences of composition of heavy metal contaminated water and fish collected at Head Balloki (River Ravi) were evaluated. 3 samples of water were collected at six different sights of Head Balloki for each Pre and Post Monsoon. Fish samples were collected at some six sights and their gills, liver were removed for heavy metal analysis. This study reported that the Concentration of chromium Cr was found higher than the Nickel Ni in water Cr > Ni. On the other hand, in fish organ of Labeo rohita the concentration of Chromium Cr was higher than the Ni in Gills Cr > Ni and the concentration of Ni was higher than the chromium Cr in Liver Ni > Cr. All the samples were analyzed to determine the concentration of two heavy metals (Cr, Ni) using Spectrophotometer techniques. The data thus obtained were analyzed, statistically. Research must also analyze the relationship between water and heavy metals and metal levels detected in fish.
