摘要
文章基于2012年与2013年对吕泗渔场两次调查分析的基础上,对吕泗渔场有机氯农药污染状况进行了分析。分析结果显示:吕泗渔场受到有机氯农药一定程度上的污染。受吕泗渔场潮流的影响,水体和沉积物中的有机氯农药分布均呈现南部海域明显高于北部海域,北部海域远岸高于近岸,南部海域近岸高于远岸的分布趋势。通过对α-666和γ-666的含量比值分析,吕泗渔场可能存在新的污染源。
Based on the twice investigations of Lvsi fishing ground in 2012 and 2013 ,the Lvsi fishing ground OCPs pollution was analyzed. The results showed that Lvsi fishing ground was polluted by OCPs to some extent. Affected by Lvsi fishing ground trend, the distribution of OCPs in water and sediment over southern waters was significantly higher than northern area; in northern waters , the distribution dictant offshore was higher than offshore waters;while in the southern waters, was the opposite. By the content of α-666 and γ-666 ratio analysis, there may be a new pollution source in Lvsi fishing ground.
