摘　　要：采样分析了来自中国西南地区6个生活垃圾填埋场的渗滤液、3个生活垃圾焚烧厂的渗滤液原液及场内处理出水,发现3种水样中17种全(多)氟化合物(PFAS)浓度分别在1805~43310,7228~16565和55~185ng/L之间;呈现以全氟丁烷羧酸(PFBA)和全氟丁烷磺酸(PFBS)等短链、偶数链PFAS为主的污染特征.对比位于相近地理区域的焚烧厂和填埋场渗滤液,发现两者PFAS组成类似,而前者PFAS浓度与运行时间为2a的填埋场渗滤液相似,高于运行时间较长(15a)的填埋场渗滤液.研究结果将为我国西南地区垃圾渗滤液PFAS赋存现状提供基础信息,并为预防和控制PFAS产品生产和使用带来的环境污染提供重要数据支持.This study sampled and analyzed 6 municipal solid waste(MSW)landfill leachates and 3 raw and treated MSW incineration leachates in southwestern China.The concentrations of 17 target PFAS ranged from 1805 to 43310,7228 to 16565,and 55 to 185ng/L,respectively.The major PFAS were short-chain and even-chain substances represented by perfluorobutanoic acid(PFBA)and perfluorobutane sulfonic acid(PFBS).Comparison of landfill and incineration leachates in the similar service area revealed that PFAS compositions in both leachates were similar.The PFAS concentrations in raw incineration leachates were higher than that of“old”landfill leachates(operation time:~15a)and similar to“young”landfill leachates(operation time:~2a).These results will provide the PFAS occurrence data important for prevention and control of environmental pollution due to PFAS production and use in southwest China.
