对2014年11月在广西茅尾海近岸35个站位采集的表层沉积物进行17种邻苯二甲酸酯(PAEs)定性、定量分析,研究了茅尾海近岸表层沉积物中PAEs的化学组成、含量及分布特征.结果从茅尾海近岸表层沉积物中共检出12种PAEs,分别为DEHP、DBP、DIBP、BBP、DnHP、DIHP、DMP、DUDP、DiPP、DAP、DEP、DMEP;其中nPiPP、DnPP、DINP、DNOP和DIDP未检出.PAEs总含量为7.94~4.28×102 ng·kg-1之间,平均值为1.23×102 ng·kg-1.茅尾海近岸沉积物中PAEs化学组成以DEHP、DnHP、DIBP、BBP、DBP为主,平均值分别为64.0、22.6、13.5、11.5、7.32 ng·kg-1,这5个组分占检出的12种PAEs质量分数97.08%.茅尾海近岸沉积物中PAEs含量分布呈现西岸高于东岸,地理位置上钦州-康熙岭-茅岭大桥段最高,其次为沙井港-钦州港段,茅岭大桥-龙门段最低.根据该文结果和参照美国土壤PAEs 控制标准,茅尾海近岸沉积物中PAEs整体污染较轻,潜在生态风险低.
對2014年11月在廣西茅尾海近岸35箇站位採集的錶層沉積物進行17種鄰苯二甲痠酯(PAEs)定性、定量分析,研究瞭茅尾海近岸錶層沉積物中PAEs的化學組成、含量及分佈特徵.結果從茅尾海近岸錶層沉積物中共檢齣12種PAEs,分彆為DEHP、DBP、DIBP、BBP、DnHP、DIHP、DMP、DUDP、DiPP、DAP、DEP、DMEP;其中nPiPP、DnPP、DINP、DNOP和DIDP未檢齣.PAEs總含量為7.94~4.28×102 ng·kg-1之間,平均值為1.23×102 ng·kg-1.茅尾海近岸沉積物中PAEs化學組成以DEHP、DnHP、DIBP、BBP、DBP為主,平均值分彆為64.0、22.6、13.5、11.5、7.32 ng·kg-1,這5箇組分佔檢齣的12種PAEs質量分數97.08%.茅尾海近岸沉積物中PAEs含量分佈呈現西岸高于東岸,地理位置上欽州-康熙嶺-茅嶺大橋段最高,其次為沙井港-欽州港段,茅嶺大橋-龍門段最低.根據該文結果和參照美國土壤PAEs 控製標準,茅尾海近岸沉積物中PAEs整體汙染較輕,潛在生態風險低.

This paper made a research on the surface sediments of Maowei sea in Guangxi province on Nov.,2014. This paper aim to research the distribution and chemical composition of phthalic acid esters (PAEs) by the method of gas chromatography-MS detector (GC-MS). The result shows, 17 kinds of PAEs were determined in the surface sediments, and 12 PAE compounds were detected. They are DEHP, DBP, DIBP, BBP, DnHP, DIHP, DMP, DUDP, DiPP, DAP, DEP, DMEP. The nPiPP, DnPP, DINP, DNOP and DIDP were not detected. The contents of 12 PAE compounds were 7.94~4.28×102ng·kg-1, with the average of 1.23×102ng·kg-1. During the 17 kinds of PAEs, the main ingredients of Maowei sea were DEHP, DnHP, DIBP, BBP and DBP, the average content were 64.0 , 22.6, 13.5, 11.5, 7.32 ng·kg-1. They account for PAEs content of 97.08%. The distribution of PAEs in west coast is higher than the east coast in Maowei Sea littoral. The highest content ofΣPAEs was the Qinzhou-KangXi-MaoLing Bridge zone, and the MaoLing Bridge-LongMen was lowest. According to the result and the American soil PAEs control standards, the slight pollution level of PAEs was obtained in the sediments of Guangxi Maowei sea littoral, and the ecological risk was low.
