ABSTRACT

Organochlorine Pesticides (OCPs) are the preserving pollutant in water which attracts the attention of chemists worldwide for several years. In this study OCPs provide a detailed data regarding concentrations, bioaccumulation and risk assessment. For this aim, 32 samples were collected from District Nowshera from surface and ground water. The most well analyzed pesticides in water-samples detected were Heptachlor, Dieldrin,?-BHC,4,4'-DDE, Chlorpyrifos, p,p'-DDD and o,p'-DDD. However, other pesticides such as o,p'-DDT, and 4,4'-DDT, were found in trace amount. However Dieldrin was found in 06 samples having concentration of 0.023 µg L-1and0.029 µg L-1 in surface and ground water respectively. To assess the possible adverse effects of organochlorine pesticides in surface and ground-water samples in the Nowshera District, the health risk assessments of detected pesticides were also traced-out. It can be concluded that the water of Nowshera district may also have carcinogenic effects due to heptachlor and dieldrin. In most groundwater samples, the risk of cancer in children and adults through drinking water for heptachlor, aldrin and dieldrin was greater than the acceptable risk level recommended by the US Environmental Protection Agency for carcinogens (1 × 10?6).
