中文摘要:本文采集并分析了峰峰矿区16件不同类型的水体样品,对样品中16种多环芳烃( PAHs) 的含量进行了对比分析,运用同分异构体比值法分析判断了其污染来源,并进行了生态风险评价。结果表明:∑PAHs在不同水体赋存浓度存在明显差异,地表水>矿井水>煤系基岩水>潜水≥奥灰水。潜水,奥灰水,矿井水和煤系基岩水中PAHs环数组成主要是以Nap、Phe和Flu为主的二、三环,而地表水主要是以Flt,BaA,Pyr,BaP和InP为主的中高环。Any/(Any Phe)和Flt/(Flt Pyr) 的比值显示奥灰水和地表水中PAHs来自于煤和生物质的燃烧;煤系基岩水,矿井水和潜水PAHs来自于石油泄露,煤和生物质的燃烧的双重来源。生态风险评价结果表明潜水,矿井水,煤系基岩水和奥灰水中16种PAHs处于低风险状态;地表水中BaA和BbF 处于中等风险,其余PAHs处于低风险状态,应该引起重视并适当采取控制和修复措施。

Distribution Characteristics and Ecological Risk Assessment of Polycyclic Aromatic Hydrocarbons in Different Types of Water in Fengfeng Mining Area
Abstract:The paper collected 16 Different Types of Water samples of the Fengfeng mining area。Using the method of isomers ratio,distribution characteristics and pollution sources of the 16 PAHs content were analysized. The results showed that.ΣPAHs in different water concentrations were significantly different. ∑PAHs concentration in surface water> mine water> coal bedrock water>shallow groundwater≥ karst groundwater. The composition of PAHs in the water of shallow groundwater, mine water, and coal bedrock water were mainly composed of Nap, Phe and Flu,surface water was mainly Flt, BaA, Pyr, BaP And InP of the high ring body. The ratio of Any / (Any Phe) with Flt / (Flt Pyr) showed that the PAHs sources in karst groundwater and surface water were derived from coal and biomass combustion, at the same time , PAHs sources in coal bedrock water, mine water and shallow groundwater were derived from oil sources with coal and biomass combustion. PAHs in the shallow groundwater, mine water, coal bedrock water and karst groundwater were at low risk. Simultaneously, BaA and BbF monomers in surface water were at medium risk,the others at low risk. Surface water should be payed attention seriously.
