- 摘要：采用较快速、简便的方法,用GC/ECD对珠江三角洲几个城市中的污水及深圳河、大沙河中的有机氯化合物进行了初步探查及半定量分析。结果表明,几种有机氯农药尽管已停止生产多年,但在污水及河水中仍有残留,其中DDT及其衍生物DDE含量在0.02-0.50μg/L范围内；BHCs在0.04-0.72μg/L范围内。氯苯类化合物及PCBs在污水及河水中也被检出。
- Abstract：Samples of river water and sewage collected from three cities (Guangzhou,Shenzhen and Zhaoqing)in the Pearl River delta were analyzed for ten PCB congeners,chlorobenzenes and chlorinated pesticides (BHC and DDT).The results showed that the concentrations of PCBs in sewage are higher(the highest value of 19 ng/L in sewage form Shenzhen was recorded) than those in river water (the lowest value of 1.0 ng/L was detected in Dasha River,Shenzhen).Total contents of chlorobenzens ranged from 0. 01 to 0. 12 μg/L with the highest value observed in the sewage from Dasha River while the sewage from Zhaoqing ranked second.The concentrations of organic chlorinated pesticides (α-BHC,γ-BHC,δ-BHC,DDT and DDE) varied little in among water samples except the sewage from Guangzhou,indicating a residual origin.
