AB  - Organochlorine pesticides (OCPs), such as hexachlorocyclohexane (HCH) and 
      dichlorodiphenyltrichloroethane (DDT), are ubiquitous anthropogenic environmental 
      contaminants. They are persistent, broad-spectrum toxicants that accumulate in 
      the food web with potential risks to the ecosystem and human health. HCHs were 
      the predominant contaminants in Baiyangdian Lake, North China. Concentrations of 
      HCHs and DDTs ranged from 58 to 563 ng/g lipid weight (lw) and 21 to 401 ng/g lw, 
      respectively, for aquatic biota samples. The highest levels of HCHs and DDTs were 
      observed in muscles of yellow catfish. The mean concentrations of OCPs were 4.6 
      ng/L for water, 95 ng/g dry weight (dw) for aquatic plants, and 14 ng/g dw for 
      sediments. Among the isomers and metabolites, alpha-HCH and 
      p,p'-1,1-di(p-chlorophenyl)-2,2-dichloroethylene (p,p'-DDE) were the predominant 
      congeners in biota samples. Correlations between log lipid-normalized 
      concentrations of HCHs and DDTs and trophic levels (TLs) based on analysis of 
      stable isotopes of nitrogen confirmed that persistent organic pollutants were 
      magnified in the Baiyangdian Lake food web. Significant positive relationships 
      were found for alpha-HCH and p,p'-DDT and their trophic magnification factors, 
      which were 1.6 and 1.7, respectively. These results provide evidence of 
      biomagnification of persistent organic pollutants (POPs) in freshwater food webs.
