重庆典型岩溶区地下河水体有机氯农药污染初步研究
A preliminary study of OCPs in underground river water in Chongqing typical karst area
摘要
Abstract
Organochlorine pesticides (OCPs) in underground river water in Chongqing typical karst area was analyzed by GC-ECD. The results show that concentration of OCPs ranges from 3.41 to 51.34 ng/L with an average of 13.23 ng/L;the concentration of DDTs ranges from 0.07 to 2.37 ng/L with an average of 0.72 ng/L;the concentration of HCHs ranges from 1.16 to 39.82 ng/L with an average of 7.89 ng/L. Wantan underground river is the most seriously polluted river in Nanchuan with the concentration of OCPs reaching 51.34 ng/L, which mainly resulted from the paper mills' waste water discharge. Comparing with other surface rivers in the world, the concentration of OCPs is in low level in the underground river. Due to the binary structure in karst area, once contaminated, it will have an impact on the underground river. Therefore, the investigation of underground river has important practical significance.关键词
