摘要
多环芳烃(PAHs)由于其致癌、致畸、致突变特性,近年来广受关注。文章通过采样测定湖州市德清县乾元镇附近水系中11处表层沉积物和水中PAHs,分析可见研究区域内PAHs主要存在于表层沉积物、区域内沉积物和水体中PAHs的主要来源来自于石油源以及煤、草、木材等生物燃料的燃烧。通过生态风险水平分析,水体中PAHs的生态风险为中低风险,暂不会对当地生态环境造成明显影响,但部分PAHs单体存在一定潜在生态风险,仍需持续监测和关注。
Polycyclic Aromatic Hydrocarbons(PAHs)pollution has been attracted much attention due to their carcinogenic,teratogenic and mutagenic properties.In this paper,the concentrations of PAHs in surface sediments and water in Qianyuan Town,Deqing,Huzhou were studied.The results showed that PAHs mainly existed in sediments.PAHs in sediments and water mainly came from petroleum sources and the combustion of biofuels such as coal,grass and wood.According to the ecological risk level analysis,the ecological risk of PAHs in water was low or medium,which would not cause an obvious impact on the local ecological environment temporarily.However,some PAHs had certain potential ecological risks,which need to be monitored and concerned continuously.
