摘要

新出现的污染物(ECs)对生态环境和人类健康都构成重大风险。垃圾填埋场沥滤液(LL)中的EC含量通常较高,对局部地下水构成潜在风险。本研究旨在分析中国东北地区城市固体废物填埋场(MSWL)和危险废物填埋场(HWL)的导电率特征。研究分别选取了中国东北地区不同类型、不同运营年限和不同防渗层的 1 个和 3 个危险废物填埋场和城市固体废物填埋场作为案例。对渗滤液和地下水环境中的九项ECs的62个指标进行统计分析,结果表明存在全氟化合物(PFCs)、抗生素、烷基酚(APs)和双酚A(BPA)。四个垃圾填埋场渗滤液中的全氟化合物、抗生素、烷基酚和双酚 A 的 ECs 浓度分别为 21.03 μg/L、40.04 μg/L、14.54 μg/L 和 43.05 μg/L。地下水中氨基甲酸乙酯的最高浓度与沥滤液中氨基甲酸乙酯的最高浓度以及垃圾填埋场的运行时间呈正相关;相反,地下水氨基甲酸乙酯与防渗程度呈负相关。这项研究可为今后中国(尤其是东北地区)垃圾填埋场和危险废物场地的导电率管理提供指导。

Emerging Contaminants in Landfill Leachate and Groundwater: A Case Study of Hazardous Waste Landfill and Municipal Solid Waste Landfill in Northeastern China
Emerging contaminants (ECs) present a significant risk to both the ecological environment and human health. Landfill leachate (LL) often contains elevated EC levels, posing a potential risk to localized groundwater. This study aimed to characterize ECs in municipal solid waste landfills (MSWLs) and hazardous waste landfills (HWLs) in northeast (NE) China. One and three HWLs and MSWLs in NE China with varying types, operational years, and impermeable layers were selected as case studies, respectively. Statistical analysis of 62 indicators of nine ECs in leachate and the groundwater environment indicated the presence of perfluorinated compounds (PFCs), antibiotics, alkylphenols (APs), and bisphenol A (BPA). The leachates of the four landfills exhibited elevated concentrations of ECs of 21.03 μg/L, 40.04 μg/L, 14.54 μg/L, and 43.05 μg/L for PFCs, antibiotics, Aps, and BPA, respectively. There was a positive correlation between the highest concentrations of ECs in groundwater and those in leachate as well as with operational duration of the landfill; in contrast, groundwater EC was negatively correlated with the degree of impermeability. This study can guide future management of ECs in landfills and hazardous waste sites in China, particularly in NE China.

期刊介绍: Water (ISSN 2073-4441) is an international and cross-disciplinary scholarly journal covering all aspects of water including water science and technology, and the hydrology, ecology and management of water resources. It publishes regular research papers, critical reviews and short communications, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
