Abstract EN
The levels of 18 organochlorine pesticides (OCPs) in the water from Lake Chaohu were measured by a solid phase extraction-gas chromatography-mass spectrometer detector.
The spatial and temporal distribution, possible sources, and potential ecological risks of the OCPs were analyzed.
The annual mean concentration for the OCPs in Lake Chaohu was 6.99 ng/L.
Aldrin, HCHs, and DDTs accounted for large proportions of the OCPs.
The spatial pollution followed the order of Central Lakes > Western Lakes > Eastern Lakes and water area.
The sources of the HCHs were mainly from the historical usage of lindane.
DDTs were degraded under aerobic conditions, and the main sources were from the use of technical DDTs.
The ecological risks of 5 OCPs were assessed by the species sensitivity distribution (SSD) method in the order of heptachlor > γ-HCH > p,p′-DDT > aldrin > endrin.
The combining risks of all sampling sites were MS > JC > ZM > TX, and those of different species were crustaceans > fish > insects and spiders.
Overall, the ecological risks of OCP contaminants on aquatic animals were very low.
