大量的危险化合物可能存在于垃圾填埋场的沥滤液中，其中许多尚未被确定。因此，本研究筛选样品从12个瑞典市政垃圾填埋场的400个参数和化合物。检测到90多种有机和金属有机化合物以及50种无机元素，其中有些元素以前似乎没有检测到。检测到的化合物包括卤代脂肪族化合物、苯和烷基化苯、苯酚和烷基化苯酚、乙氧基化物、多环芳香族化合物、邻苯二甲酸酯、氯化苯、氯化苯酚、多氯联苯、氯化二恶英和氯化呋喃、溴化阻燃剂、农药、有机锡、甲基汞和重金属。垃圾填埋场沥出液中存在大量的危险化合物，这对今后的垃圾填埋场风险评估和沥出液处理方法的发展将产生重大影响。我们建议未来的研究应更多地关注本研究中检测到的金属有机物和有机化合物。我们还建议使用沥滤液沉积物作为检测疏水化合物的基质，并在评价监测研究结果时反映降解阶段。本文中化合物的广泛汇编可用于选择化合物以在未来的研究中搜索。
A large number of hazardous compounds can be expected to be present in landfill leachates, many of which have not yet been identified. Thus this study screened samples from 12 Swedish municipal landfill sites for 400 parameters and compounds. More than 90 organic and metal organic compounds and 50 inorganic elements were detected, some of which seem to have not been detected before. Compounds detected include halogenated aliphatic compounds, benzene and alkylated benzenes, phenol and alkylated phenols, ethoxylates, polycyclic aromatic compounds, phthalic esters, chlorinated benzenes, chlorinated phenols, PCB, chlorinated dioxins and chlorinated furans, bromated flame-retardants, pesticides, organic tin, methyl mercury and heavy metals. The presence of this large number of hazardous compounds in landfill leachates should have a significant impact on future landfill risk assessments and the development of leachate treatment methods. We propose that future research should pay more attention to the metal–organic and organic compounds detected in this study. We also suggest using leachate sediments as a matrix for detecting hydrophobic compounds, and reflecting on the degradation phase when evaluating results from monitoring studies. The extensive compilation of compounds in this paper can be used to select compounds to search for in future studies.
