摘要
对广西钦州湾近江牡蛎(Crassostrea rivularis)体有机氯农药(HCHs和DDTs)和多氯联苯(PCBs)的残留水平进行监测与分析。结果表明:近江牡蛎体中HCHs、DDTs和PCBs的质量比分别为ND～0.23μg/kg、0.01～0.21μg/kg和ND～2.3μg/kg;检出率分别为45%、100%和95%,3种污染物含量符合国家《海洋生物质量》第一类标准和无公害水产品质量要求。相对国内其他海区而言,钦州湾近江牡蛎受HCHs、DDTs和PCBs污染程度处于低污染水平。
Levels and distributions of residual organochlorinated presticides（HCHs and DDTs） and PCBs in Crassostrea rivularis from Qinzhou Bay were monitored and analyzed. The mass ratios of HCHs, DDTs and PCBs in C. rivularis from Qinzhou Bay were ND-0.23μg/kg, 0.01-0.21μg/kg and ND-2.3μg/kg, respectively; the detection rates were 45%, 100% and 95%, respectively. The concentrations of these three pollutants reach the first class standard of National Marine Biological Quality and the quality requirement of Pollution-Free aquatic products In comparison with other domestic areas, the pollution levels of HCHs, DDTs and PCBs were lower.
