应用毛细管柱气相色谱技术对大连近海的贻贝、牡蛎体中的有机氯农药和多氯联苯进行了分析研究;贻贝、牡蛎样品中有机氯和多氯联苯经超声提取、柱色谱分离后 ,由GC -ECD测定 ,检出了8种有机氯农药(α_666、β_666、γ_666、δ_666、o,p′_DDE、p,p′_DDE、p,p′_DDD、p,p′_DDT)和10种多氯联苯(PCB28、PCB52、PCB155、PCB101、PCB112、PCB118、PCB153、PCB138、PCB180、PCB198);有机氯农药含量分布在0.16×10-9～37.9×10-9(w)之间 ,回收率为77 %～89% ;多氯联苯含量分布在0.03×10-9～28.9×10-9(w)之间 ,回收率为75 %～101%。
The organochlorine pesticides and polychlorinated biphenyls in the mussels and oysters near the sea of Dalian were analyzed by capillary gas chromatography. The organochlorines and polychlorinated biphenyls in the samples of mussels and oysters were extracted by ultrasonic and separated by column chromatography Eight organochlorine pesticides (α_666, β_666, γ_666, δ_666, o, p’_DDE, p, p’_DDE, p, p’_DDD, p, p’_DDT) and 10 kinds of PCBs (PCB28, PCB52, PCB155, PCB101, PCB112, PCB118, PCB153, PCB138, PCB180, PCB198); the content of organochlorine pesticides was between 0.16 × 10-9 ~ 37.9 × 10-9 , The recoveries ranged from 77% to 89%. The PCBs content ranged from 0.03 × 10-9 to 28.9 × 10-9 (w), and the recoveries ranged from 75% to 101%.
