桑沟湾水体中有机氯农药和多氯联苯的浓度水平及分布特征

Fifteen organochlorine pesticides(OCPs) and polychlorinated biphenyls(PCBs) in seawaters of the Sanggou Bay were determined by using quantitative GC/ECD with external standards.The recovery for the blank was in the range 88.9% to 110.1%,and the relative standard deviation was 2.5%~8.5%;the recovery for the samples was in the range 89.4% to 115.2%,and the relative standard deviation was 3.4%~11.3%.The linearity range of the method was 2.5~250 ng/L,and the detection limit was 0.22~1.05 ng/L.Six organochlorine...
