Carcinogenic Effects

Organochlorine pesticides (OCPs) including Hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethanes (DDTs) in surface water of Lake Baiyangdian were determined to assess the potential health risk when using as drinking water for children and adults. The concentration of HCHs and DDTs in surface water were in the range of 2.74-11.50 ng L-1 and 3.48-16.88 ng L-1, respectively. Compared with similar results reported around the world, the level of OCPs in this study was in the mid-range. The analysis of health risk indicated that risks from OCPs in most part of the lake would not be risky to human health according to the acceptable risk level, while carcinogenic effects caused by α-HCH might occur if drinking water from Nanliuzhuang (NLZ) and Laowangdian (SCD). α-HCH and β-HCH were the dominating factors for carcinogenic and non-carcinogenic risks, respectively. Risks of OCPs for children were much higher than those caused by OCPs for adults.
