Municipal solid waste landfilling, landfilling process and landfill reclamation result in leachate, which may be dangerous to the environment. Municipal solid waste leachate phytotoxicity tests were performed using the toxicity test and a subchronic toxicity pot experiment by direct application of leachate to reference soil in 5, 25, and 50% concentration for a period of 28 days. White mustard (Sinapis alba L.) seeds were exposed to different leachate dilution. Leachate were collected monthly in 2018 in the period from April to September. Furthermore, pH, conductivity, and dissolved oxygen were measured. The inhibition results on Sinapis alba L. seeds in the tested leachate samples ranged from −18.02 to 39.03%. Lower concentration of leachate showed a stimulating effect (only for Sample 1 and Sample 2 at 5% concentration). It was found out that leachate taken at the landfill is phytotoxic. The results of measurements are based on rainfall which affects the quantity and quality of the leachate. The values of germinated seeds/growing plants from the subchronic toxicity pot experiment ranged from 80 to 104%; therefore, the leachate is considered phytotoxic. However, it was confirmed that leachate may be used for landfill irrigation.

城市生活垃圾填埋场渗滤液的植物毒性评价：以布科夫垃圾场为例

城市生活垃圾填埋，填埋过程和填埋场填埋会产生渗滤液，这可能对环境造成危害。使用毒性试验和亚慢性毒性盆栽试验进行市政固体垃圾渗滤液的植物毒性试验，方法是将渗滤液直接以5％，25％和50％的浓度施用到参考土壤中28天。将白芥菜（Sinapius alba L.）种子暴露于不同的沥滤液稀释液中。2018年4月至9月每月收集一次渗滤液。此外，测量pH，电导率和溶解氧。对白芥的抑制作用测试的沥出液样品中的L.种子的范围为-18.02％至39.03％。较低的浸出液浓度显示出刺激作用（仅对于浓度为5％的样品1和样品2）。已发现在垃圾填埋场抽取的渗滤液具有植物毒性。测量结果基于降雨，降雨会影响渗滤液的数量和质量。亚慢性毒性盆栽试验的发芽种子/生长植物的值在80％到104％之间；因此，渗滤液被认为具有植物毒性。然而，已证实沥滤液可用于垃圾填埋场灌溉。
