The inevitable consequence of the operation of landfills is the emission of leachate, which is considered to be one of the main polluters of the ground and water environment. The leachate contains soluble organic compounds, inorganic contaminants, suspended solids, heavy metals and dangerous substances. The selection of the leachate disposal method requires a comprehensive assessment of its properties. Therefore, the physicochemical parameters and toxicity tests were chosen for a comprehensive assessment of the properties of leachate. Four municipal waste landfills (operational and non-operational) were selected for the study, for which multidimensional statistical analyses were carried out. The study was conducted between the period of April 2018 and December 2019. The comprehensive assessment showed that pollutants in leachate from the analyzed landfills remained at a level which did not allow them to be discharged to water or soil. The presence of substances particularly harmful to the aquatic environment (e.g AN, chromium, copper) may hinder their treatment together with household sewage, as it involves obtaining a permit required under laws. Toxicity of leachate may also be a problem, as it may persist after the treatment process is completed. The values of pH, EC and the concentrations of ON, TDS, TSS, chloride, iron and manganese had the strongest influence on the properties of leachate from all landfills. For operational landfills, these were also calcium concentrations, for non-operational ones COD, TU and the concentrations of TKN, AN, TS, sodium, potassium and magnesium. The mentioned parameters also showed strong correlation with other physicochemical properties of the leachate, which indicate their suitability for the monitoring of leachate and the aquatic environment in the vicinity of municipal waste landfills.

垃圾填埋场运营的必然后果是渗滤液的排放，渗滤液被认为是地面和水环境的主要污染源之一。渗滤液含有可溶性有机化合物、无机污染物、悬浮固体、重金属和危险物质。渗滤液处理方法的选择需要对其性质进行综合评估。因此，选择理化参数和毒性试验来综合评估渗滤液的性质。研究选择了四个城市垃圾填埋场（运营和非运营），并对其进行了多维统计分析。该研究是在 2018 年 4 月至 2019 年 12 月期间进行的。综合评估表明，所分析的垃圾填埋场渗滤液中的污染物仍处于不允许排放到水或土壤中的水平。对水生环境特别有害的物质（例如 AN、铬、铜）的存在可能会阻碍它们与家庭污水一起处理，因为这涉及获得法律要求的许可。渗滤液的毒性也可能是一个问题，因为它可能会在处理过程完成后持续存在。pH、EC值和ON、TDS、TSS、氯化物、铁和锰的浓度对所有垃圾填埋场渗滤液的性质影响最大。对于运营垃圾填埋场，这些也是钙浓度，对于非运营垃圾填埋场，COD、TU 和 TKN、AN、TS、钠、钾和镁的浓度。
