- 摘要：对珠江三角洲流经城市的7条河流和3条干流水道(东、西、北江)以及广州、深圳、肇庆的城市污水中的半挥发性微量有机污染物进行了分析,并对其污染状况以及污染来源进行了初步评价。研究表明,珠江三角洲内流经城市的7条河流受到的有机物污染比3条干流水道严重得多。氯代芳烃、正烷烃、酞酸酯和多环芳烃是珠江三角洲水体中最普遍存在的微量有机物污染物,其中属于EPA优先控制的污染物有12种,“EPA协议法令”规定的污染物有13种。
- Abstract：Investigation on organic micropollutants in seven rivers of the waterway network and the three main tributaries of the Pearl River in the Pearl River Delta Region has been conducted. The results showed that the rivers in the waterway network were more heavily contaminated by the organics than the three main tributaries. Chlorinated aromatics, n alkanes, phthalate and PAHs were the most common compounds detected in the water samples analyzed, of them twelve are USEPA priorith pollutants and thirteen are listed as toxic pollutants in “ EPA Agreement C”. Although DDT and BHCs had been inhibi ted for years, the compounds were detected in some rivers and sewage waters from the area studied. The total concentrations of chlorinated pesticides were from 0.11 to 1.22μg/L, polychlorinated biphenyl's(PCBs) were also investigated in the waters.
