“…Aquatic biota are frequently used as biological indicators to monitor the levels of Persistent Organic Pollutants (POPs) in aquatic environments (van der Oost et al, 2003;Lanfranchi et al, 2006;Guo et al, 2008;Zhao et al, 2013;Lacorte et al, 2006;Jaspersa et al, 2013), to analyze POP bioaccumulation (Haruhiko et al, 2003;Arnot and Gobas, 2006;van Leeuwen et al, 2008;Coat et al, 2011) and biomagnification in the food chain (Hu et al, 2010;Zhang et al, 2013;Villa et al, 2011;Li et al, 2008b), and to evaluate human health risks associated with the consumption of contaminated water products (Dong et al, 2006;Cheung products, such as lindane (which is 99% gamma-HCH) and dicofol (which contains DDT analogs that form as manufacturing impurities), are still used in some regions of China (Qiu et al, 2005), and DDT is also used as a secondary material in antifouling paint for ships (Yu et al, 2011). As a result, OCPs have continued to be detected in water and aquatic biota throughout China in recent years (Li et al, 2007;Guo et al, 2008;Tao et al, 2005Tao et al, , 2008He et al, 2012;Xu et al, 2013;Ouyang et al, 2012Ouyang et al, , 2013Ouyang et al, , 2014.…”
