摘要: 对枯水期和丰水期长江河口区5个断面不同深度水样进行检测,共检出有机物200余种,其中定量检出的有机物达53种,有36种属美国EPA控制的有毒有机化合物,列入中国环境优先控制污染物黑名单的有16种。枯水期N-二甲基亚硝胺含量较高,最高值约为1.2 mg.L-1。丰水期2,4-二硝基酚、邻苯二甲酸二丁基苯基酯含量较高,最高值分别约为1.3和1.0 mg.L-1。底层水中有机污染物浓度高于表层和中层。

Abstract: More than 200 kinds of organic pollutants were detected in water samples collected from different depths of five monitoring sections in estuary of the Yangtze River in dry and flood seasons.Among the 53 quantitatively measured kinds,36 kinds were in the list of venomous organic compounds specified by EPA of the USA for control,and 16 kinds in the blacklist of China for priority control in environment protection.In the dry season,N-dimethylnitrosamine was the highest in concentration with the maximum value reaching up to 11.2 mg·L-1,while in the flood season,2,4-dinitrophenol and butylbenzyl phthalate were high in concentration with the highest to be 1.3 and 1.0 mg·L-1,respectively.The concentration of organic pollutants in the deep water layer was higher than in the surface and middle layers.

Key words: estuary, Yangtze River, organic pollutant, chemical analysis
