在黄渤海近岸海域采集了34个水体样品,利用HPLC-MS/MS分析了双酚A、辛基酚、壬基酚、2,4-二氯酚、对叔丁基苯酚和对特辛基苯酚等6种酚类内分泌干扰物的含量,并探讨了其分布特征及来源.结果表明,中国北部近岸海域6种酚类内分泌干扰物的含量范围在5.25～1351.20ng/mL之间.结合因子分析和层次聚类分析结果,说明渤海、黄海近岸海域中酚类化合物主要以辛基酚、壬基酚、2,4-二氯酚为主,局部海域伴有双酚A的高残留;从整个海域范围看,黄渤海近岸海域水体中酚类化合物污染状况具有区域特征,整体呈现出南高北低的特点,且酚类物质分布具有明显的地区特性,一定程度上具有聚集性;来源解析结果表明黄渤海近岸海域中酚类内分泌干扰物主要来源为生活污水和工业废水.
A total of 34 water samples were collected from the coastal areas of the Yellow Sea and the Bohai Sea. The contents of bisphenol A, octylphenol, nonylphenol, 2,4-dichlorophenol, p-tert-butylphenol and p- Phenols and other six kinds of phenolic endocrine disruptors content and to explore its distribution characteristics and sources.The results show that the content of six kinds of phenolic endocrine disruptors in the coastal waters of northern China range between 5.25 ~ 1351.20ng / mL. Combining the results of factor analysis and cluster analysis, it shows that the phenolics in the Bohai Sea and Yellow Sea coastal areas are mainly octylphenol, nonylphenol and 2,4-dichlorophenol, and the high level of BPA The whole area of the Yellow Sea and the Bohai Sea, there is a regional characteristic of the pollution of phenolic compounds in the waters around the Yellow Sea and the Bohai Sea, showing the characteristics of high south and north and low, and the distribution of phenols has obvious regional characteristics, to a certain extent, The results of source analysis indicated that the main sources of phenolic endocrine disruptors in the coastal areas of the Yellow Sea and the Bohai Sea were domestic sewage and industrial wastewater.
