| 摘 要： | 对北京市2个季度(枯水和丰水期)的水源水进行水质调查,针对不同性质的有机污染物,采用HLB或C18固相萃取柱富集水样并用GC/MS仪对数据进行检测,分析了北京市9个采样地点饮用水水体中多环芳烃(Polycyclic Aromatic Hydrocarbons,PAHs)、有机氯农药(Organic Chlorine Pesticide,OCPs)和酚(Hydroxybenzene,Phenols)的含量水平,明确北京市饮用水中主要有机污染物的类型和分布规律,并简要讨论了可能的产生因素.结果发现,只有枯水季样点8进水PAHs中的苯并a]芘超标,其余各物质均未超过规定的上限值.但PAHs和OCPs中致癌性有机物所占的比例相对较高,达到了50%以上,需要继续监测和控制.

| Abstract: | Quality of source water for municipal waterworks in Beijing during two seasons (dry and wet, respectively) was investigated. Water samples were collected at 9 sites. Based on the characteristics of individual organic pollutant, levels of PAHs, OCPs, and Phenols were measured with GC/MS devices. The types and distribution of the major organic pollutants in the drinking water sources among the city were determined, and possible factors contributing to the distribution pattern were discussed generally. Measurements showed that all substances except Benzo pyrene in Sample 8 in dry season were below the highest limits. However, the percentage of carcinogenic organic pollutants in PAHs and OCPs was over 50%, which should be the targets for further monitoring and control. |
