Abstract
This paper reports on the results of systematic analyses carried out to assess the distribution of dichlorodiphenyltrichloroethane (DDT) and its metabolites, o,p′-DDT, p,p′-DDE, and p,p′-DDD in a tropical waterway, the Cochin Estuarine System. Six sampling stations along the system were studied. Analyses were carried out during premonsoon, monsoon, and postmonsoon seasons. ΣDDT concentrations as high as 55.422 μg L−1 were detected. The predominant DDT metabolite was found to be p,p′-DDE. During the monsoon season, o,p′-DDT was not detected at any of the sampling Stations. Station 1 (riverine) and station 6 (coastal zone barmouth) emerged as DDT-free zones and the analytical results have enabled the identification of DDT “hot spots” in the estuary. © 1994 by John Wiley & Sons, Inc..
二氯二苯三氯乙烷(DDT)及其代谢物在印度水道中的分布
本文报道了对热带水道科钦河口水系中二氯二苯三氯乙烷(DDT)及其代谢物o,p ' -DDT、p,p ' -DDE和p,p ' -DDD的分布进行系统分析的结果。对系统沿线的6个采样站进行了研究。在季风前、季风和季风后季节进行了分析。ΣDDT浓度高达55.422 μg L−1。DDT的主要代谢物为p,p′-DDE。在季风季节，在任何采样站均未检测到o,p ' -滴滴涕。1号站(河流)和6号站(海岸带barmouth)成为无DDT区，分析结果使河口DDT“热点”得以识别。©1994 by John Wiley & Sons, Inc.。
