宁波滩涂贝类养殖区沉积物中有机氯农药和多氯联苯残留及生态风险评估
Residual level and ecological risk assessment of OCPs and PCBs in sediments of mudflat shellfish culturing areas in Ningbo, Zhejiang Province of East China
摘要
Abstract
GC-ECD methods were adopted to determine the residual level of OCPs (including HCHs and DDTs) and PCBs in the surface sediments collected from mudflat shellfish culturing areas in Ningbo, with the sources of the OCPs and PCBs analyzed and the ecological risks of the residual OCPs and PCBs evaluated. The residual level of OCPs was 0. 80-32.40 ng ·g-1, and that of PCBs was 3. 20-33. 33 ng·g-1. The HCHs mainly came from long distance atmospheric transportation and historical residues, while the DDTs had new input at some sites, possibly coming from the application of dicofol. At most sites, there existed potential ecological risks of p, p' -DDT and DDTs, with strong indications in Qiangtou and Xidian where the residual level of p, p' -DDT was higher than the effect rang median (ERM) , suggesting an ecological menace to the benthos. The residual PCBs at most sites were in low level ecological risk.关键词
