摘　　要：采用气-质联用技术分析了武汉汉阳月湖和莲花湖的4个表层沉积物样品中的有机污染物,探讨了两湖沉积物受持久性有机物污染的程度。月湖中共检测出124种有机物,其中属环境优先控制污染物和美国EPA筛选的内分泌干扰物19种;莲花湖中共检测出186种有机物,环境优先控制污染物和美国EPA筛选的内分泌干扰物34种。主要污染物包括:酞酸酯、酯类、酚类、杂环和苯及其衍生物等。污染物浓度顺序为L1>L2>Y2>Y1,莲花湖中有机物浓度明显高于月湖。两湖邻苯二甲酸酯的含量最高,占了污染物总量的96%～98%,邻苯二甲酸乙基己基酯(平均值17 599.03 ng/g干重)和邻苯二甲酸二丁酯(平均值2 515.76 ng/g干重)是两湖沉积物中的主要酞酸酯类污染物。The persistent organic pollutants of 4 surface sediment samples from Yuehu Lake and Lianhuahu Lake,Wuhan City,China, were analyzed by GC-MS. From the sediment samples of Yuehu Lake 124 kinds of organic compounds were detected, among which 19 kinds of chemicals belonged to priority pollutants or endocrine disruptors. While 186 kinds of organic compounds were detected in the sediment samples of Lianhuahu Lake,and 34 kinds belonged to priority pollutants or endocrine disruptors. The majority of the pollutants are phthalic acid, esters,phenol, benzene and its derivatives. The concentration of the pollutants in both of two lakes was L1〉L2〉Y2〉Y1 and the organic contamination levels in Lianhuahu Lake were higher than those in Yuehu Lake. The phthalic acid were on hing 96-98 percent of all pollutants. Bis（2-ehtylhexyl）pht domirfant components of the analyzed poll 2 515.76 ng/g dry weight,respectively. e highest level in all observed late and di-n-butyl phthalate samples, reaching 96-98 percent of all pollutants. Bis（2-ehtylhexyl）phthalate and di-n-butyl phthalate were the predominant components of the analyzed pollutants with the mean of 17 599.03 ng/g dry weight, and 2 515.76 ng/g dry weight,respectively.
