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.
预计垃圾渗滤液中会存在大量有害化合物，其中许多尚未被识别。因此，本研究对来自12个瑞典城市垃圾填埋场的样本进行了400项参数和化合物的筛选。检测到90多种有机和金属有机化合物以及50种无机元素，其中一些似乎以前未被检测到。检测到的化合物包括卤代脂肪族化合物、苯和烷基苯、苯酚和烷基苯酚、乙氧基化物、多环芳香化合物、邻苯二甲酸酯、氯苯、氯酚、多氯联苯、氯代二噁英和氯代呋喃、溴化阻燃剂、农药、有机锡、甲基汞和重金属。垃圾渗滤液中存在如此大量的有害化合物，应对未来的垃圾填埋场风险评估和渗滤液处理方法的发展产生重大影响。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和有机化合物。我们还建议使用渗滤液沉积物作为检测疏水性化合物的基质，并在评估监测研究结果时考虑降解阶段。本文对化合物的广泛汇编可用于选择未来研究中要寻找的化合物。
