The study assesses the contamination, classification and phytotoxicity of foundry waste. The presented results are a part of the research on the agrotechnical use of foundry waste. Landfilled foundry waste (LFW) and dust samples were taken from one of the Polish foundries. An analysis of the waste and its leachate composition was conducted. Phytotoxicity tests were carried out using Lepidium sativum. The aim of the phytotoxicity study was to evaluate germination and root growth after 72 h and the accumulation of heavy metals after 7 days. LFW was least contaminated with heavy metals and metalloids compared to dust. The composition of the foundry dusts depended on the unit of the foundry, from which it was collected. It was found that electric arc furnace dust (EAFD) was the most polluted by heavy metals among the dust samples. According to the requirements of Polish regulations most of tested waste were classified as non-hazardous, and EAFD as hazardous waste due to high Pb concentration in leachate. Phytotoxicity tests have shown a low phytotoxicity of the leachate from most of the tested waste. The results of the accumulation test showed that an excess of metal and metalloids in leachate was not directly related to its accumulation in plants. A negative correlation between EC, Cu, Co, Fe, Pb, Cr, K, Na, sulfate, fluoride, ammonia, phenol and formaldehyde concentration in leachate and GI was found. It was stated that the Fe, Mn, As and Se in plants was significantly correlated with concentrations in leachate.

评估垃圾填埋场产生的渗滤液和铸造厂产生的粉尘的植物毒性。

该研究评估了铸造废料的污染，分类和植物毒性。提出的结果是对铸造废料的农业技术用途进行研究的一部分。垃圾填埋的铸造废料（LFW）和粉尘样品是从波兰一家铸造厂获取的。对废物及其渗滤液组成进行了分析。植物毒性试验使用了番茄。植物毒性研究的目的是评估72小时后的发芽和根系生长以及7天后重金属的积累。与粉尘相比，LFW被重金属和准金属污染最少。铸造粉尘的成分取决于铸造粉尘的收集单位。发现在粉尘样品中，电弧炉粉尘（EAFD）受重金属污染最严重。根据波兰法规的要求，由于渗滤液中的Pb含量高，大多数经测试的废物被归类为无害废物，而EAFD被归类为有害废物。植物毒性测试表明，大多数测试废物中渗滤液的植物毒性较低。积累测试的结果表明，渗滤液中过量的金属和准金属与其在植物中的积累没有直接关系。浸出液和GI中的EC，Cu，Co，Fe，Pb，Cr，K，Na，硫酸盐，氟化物，氨，苯酚和甲醛浓度之间呈负相关。据指出，植物中的铁，锰，砷和硒与渗滤液中的浓度显着相关。植物毒性测试表明，大多数测试废物中渗滤液的植物毒性较低。积累试验的结果表明，渗滤液中过量的金属和准金属与其在植物中的积累没有直接关系。浸出液和GI中的EC，Cu，Co，Fe，Pb，Cr，K，Na，硫酸盐，氟化物，氨，苯酚和甲醛浓度之间呈负相关。据指出，植物中的铁，锰，砷和硒与渗滤液中的浓度显着相关。植物毒性测试表明，大多数测试废物中渗滤液的植物毒性较低。积累试验的结果表明，渗滤液中过量的金属和准金属与其在植物中的积累没有直接关系。浸出液和GI中的EC，Cu，Co，Fe，Pb，Cr，K，Na，硫酸盐，氟化物，氨，苯酚和甲醛浓度之间呈负相关。据指出，植物中的铁，锰，砷和硒与渗滤液中的浓度显着相关。发现渗滤液和胃肠道中苯酚和甲醛的浓度。据指出，植物中的铁，锰，砷和硒与渗滤液中的浓度显着相关。发现渗滤液和胃肠道中苯酚和甲醛的浓度。据指出，植物中的铁，锰，砷和硒与渗滤液中的浓度显着相关。
