摘要: 应用GC/MS技术对我国11个城市污泥和种土壤中的苯并(a)芘进行研究,探讨苯并(a)芘在城市污泥和土壤中的含量和分布特征.结果表明,城市污泥中苯并(a)芘的含量在0.007~6.578mg·kg-1之间,平均为1.272mg·kg-1,绝大部分低于1.0mg·kg-1,但在珠海和北京污泥中超过我国农用污泥的控制标准.褐土、水稻土和石灰性土中苯并(a)芘的含量分别为2.138、0.782和0.66mg·kg-1,在赤红壤中未检出.城市污泥中苯并(a)芘含量与污水来源、污水处理方式和污泥类型等因素有关,土壤中苯并(a)芘含量与母质、大气污染、污水灌溉、污泥农用等因素有关.

Abstract: Benzo(a)pyrene in municipal sludges and four types of soils from eleven selected cities in China were determined by GC MS.The results showed that the contents of b enzo(a)pyrene in sludges ranged from 0.007 to 6.578mg穔g-1 and averaged 1. 272mg穔g-1.Most of them were lower than 1.0mg穔g-1,and only two of them were higher than 3.0mg穔g-1,which was a limit value of benzo(a)pyre ne in sludge applied to agricultural land in China.On the other hand,the content s of benzo(a)pyrene in cinnamon soil,paddy soil,calcareous soil,and latosolic re d soil were 2.138mg穔g-1,0 782mg穔g-1,0.664mg穔g-1,and und er detection limit respectively.The content of benzo(a)pyrene in different munic ipal sludge was mainly related to sources of wastewater,wastewater treating met hods,sludge types,while in soils,it was mainly to parent,air pollution,wastewate r irrigation,and sewage sludge application.
