The article presents the results of phytotoxicity tests on foundry dust and landfilled waste. Currently, all this waste is being reused. The research has focused on phytotoxicity tests performed directly on the waste. Garden cress (Lepidium sativum L.) was used as the test plant. The germination test (GI) and the accumulation test were used to assess phytotoxicity. All dust types were highly phytotoxic to L. sativum L. in the direct test. The reason for this effect could be the low pH, the high level of heavy metals (HM), and probably the presence of organic pollutants (phenol, formaldehyde). The most phytotoxic was electric arc furnace dust (EAFD), classified as hazardous waste due to the high content of HM. The landfilled foundry waste (LFW) was characterised by moderate phytotoxicity in the direct test. The study confirmed the usefulness of the direct test in the phytotoxicity assessment of foundry waste with L. sativum L.
该文介绍了铸造尘和填埋废物的植物毒性测试结果。目前，所有这些废物都在被重新利用。研究集中在直接对废物进行的植物毒性测试上。使用蕗蕨（Lepidium sativum L.）作为测试植物。采用发芽试验（GI）和积累试验来评估植物毒性。所有类型的粉尘在直接测试中对蕗蕨（L. sativum L.）均具有高度的植物毒性。这种影响的原因可能是低 pH 值、高水平的重金属（HM），可能还有有机污染物（苯酚、甲醛）的存在。由于 HM 含量高，电弧炉粉尘（EAFD）被归类为危险废物，其植物毒性最大。填埋铸造废物（LFW）在直接测试中表现出中等程度的植物毒性。该研究证实了直接测试在利用蕗蕨（L. sativum L.）评估铸造废物植物毒性方面的有效性。
