This study aims to investigate the impact of MSW landfill on the contamination of phthalate esters (PAEs) in nearby environment. Landfill leachate, surface water, groundwater and soil profile samples were collected from a MSW landfill area in Wuhan, China. Contents of 16 PAEs were detected for each sample using gas chromatography method. Results showed that landfill had an obvious effect on the contamination of PAEs in groundwater, whereas showed no tremendous effect on the PAEs contamination in surface water and topsoil. Seven possible transportation processes of PAEs in landfill area were put forward. However, the especially important processes are the invasion of PAEs into aquifer through weathered crevice, horizontal transportation in aquifer and upward infiltration with groundwater. It is suggested that the whole landfill area should be engineered with seepage-proof membrane and clay so as to prevent landfill leachate from flowing out of the filling area. On the other hand, no weathering crevice is permitted in the landfill area as it will affect groundwater seriously.
本研究旨在探讨城市生活垃圾填埋场对邻域中邻苯二甲酸酯（PAEs）污染的影响。采集了来自中国武汉市某城市生活垃圾填埋场地区的垃圾渗滤液、地表水、地下水和土壤剖面样本。使用气相色谱法对每个样本中的 16 种邻苯二甲酸酯含量进行了检测。结果表明，垃圾填埋场对地下水 PAEs 的污染有明显影响，而对地表水和表土中 PAEs 污染的影响不大。提出了 PAEs 在填埋场地区的 7 种可能的迁移过程。然而，特别重要的过程是 PAEs 通过风化裂缝侵入含水层、在含水层中水平迁移以及随地下水向上渗透。建议采用防渗膜和粘土对整个填埋场区域进行工程设计，以防止垃圾渗滤液流出填埋区。另一方面，填埋场区域不允许有风化裂缝，因为这会严重影响地下水。
