瑞典西部哥德堡地区三个市政垃圾填埋场的渗滤液的特征在于其单个有机化合物的含量。在本研究期间，两个被调查的垃圾填埋场仍在使用。第三个垃圾填埋场于七十年代中期关闭。渗滤液中鉴定出 200 多种单独的有机化合物和化合物类别，浓度范围从不足 1 微克/升到数百微克/升。三个垃圾填埋场共有的化合物包括增塑剂（邻苯二甲酸盐、苯磺酰胺）、磷酸酯、取代苯酚、氯化苯酚、酚类抗氧化剂和硅氧烷，以及有机废物降解过程中形成的化合物（二氢二恶英、吡嗪和几种含硫有味挥发物）。此前未曾报道过渗滤液中发现的二恶烷和二氧戊环。旧的封闭垃圾填埋场的渗滤液中主要含有来自先前处理的石油污染废物的化合物。取代它的是一个新的区域垃圾填埋场，其渗滤液主要是醇和醚。这种差异归因于废物管理的区域措施。
Leachates from three municipal landfills in the Goteborg area of western Sweden were characterised in terms of their content of individual organic compounds. Two of the investigated landfills were still in use during the time of this study. The third landfill was closed down in the mid-seventies. More than 200 individual organic compounds and classes of compounds were identified in the leachate with concentrations ranging from less than one up to several hundred μg/L. Among the compounds common to all three landfills were plasticizers (phthalates, benzenesulfonamides), phosphate esters, substituted phenols, chlorinated phenols, phenolic antioxidants and siloxanes as well as the compounds formed during the degradation of organic wastes (dihydro-dioxin, pyrazines and several sulphur-containing odorous volatiles). Dioxanes and dioxolans found in the leachates have not been previously reported. Compounds originated from previously disposed oil contaminated wastes dominate the leachate from an old closed landfill. Its replacement, a new regional landfill has a leachate dominated by alcohols and ethers. This difference is attributed to regional measures in waste management.
