摘    要:应用GC/MS对我国内地和香港地区共11个城市污泥中的17种多环芳烃化合物(PAHs)进行了研究,各城市污泥中∑PAHs的含量在2.271-143.804mg/lg之间,依次为兰州污泥>珠海污泥>北京污泥>广州污泥>佛山污泥>无锡污泥>沙田污泥(香港)>元朗污泥(香港)>大埔污泥(香港)>西安污染>深圳污泥,含量较高的化合物主要是蒽、荧蒽、苯并(a)蒽和屈等,珠海污泥和北京污泥的苯并(a)芘含量超过我国城市污泥农用标准,各化合物的最高含量分别分布在兰州污泥、珠海污泥、北京污泥和广州污泥中,各城市污泥中的PAHs具有不同的分布特征,均以少数化合物为主,主要是3和4个苯环的化合物,2、5和6个苯环的化合物含量普遍较低。

关 键 词:城市污泥  农业利用  有机污染物  多环芳烃  PAHs  中国  废水监测

Abstract:Gas chromatography interfaced to mass spectrum (GC MS) was used to determine polycyclic aromatic hydrocarbons (PAHs) in 11 municipal sludges derived from mainland and HongKong of China. The content of PAHs in different sludges ranged from 2271mg/kg to143 80mg/kg, decreasing in the order: Lanzhou sludge>Zhuhai sludge>Beijing sludge>Guangzhou sludge>Foshan sludge>Wuxi sludge>Shatian sludge (HongKong)>Yuanlang sludge (HongKong)>Dapu sludge (HongKong)>Xi'an sludge>Shenzhen sludge. The contents of anthracene, acenaphthene, benzo(a)anthracene, and chrysene were much higher than that of any other compounds. The level of benzo(a)pyrene (B(a)P) in sludges from Zhuhai and Beijing exceeded the national standard which is fixed in 3 0mg/kg dry weight of sludge applied to agricultural land. The highest content of each compound was measured respectively in Lanzhou sludge, Zhuhai sludge, Beijing sludge, and Guangzhou sludge. Though distribution patterns of PAHs in different sludges were different, they were common in that only a few compounds with 3, 4 benzene rings were predominant, while others with 2,5, and 6 benzene rings usually minor.
Keywords:municipal sludge  agricultural use  organic pollutants  polycyclic aromatic hydrocarbons (PAHs)
