本研究涉及金属污染土壤的毒理学特性，在瑞典东南部的玻璃厂作为研究对象。从五个选定的玻璃厂网站以及从附近的参考地区的土壤进行了分析，总的和水溶性金属浓度和一般的地球化学参数。然后应用一系列生物测试来评估玻璃厂土壤环境的毒性：用花园水芹（Lepidium sativum）进行植物毒性测试;使用费氏弧菌（Vibrio fischeri）进行细菌毒性的BioTox™测试;以及分析线虫和线虫的丰度和生物量。玻璃厂和参考区的pH值和有机质和营养物质（C，N，P）的含量相媲美，但总金属浓度（铅，砷，钡，镉和锌）显着较高的前网站。还观察到水溶性部分中的较高金属浓度，尽管这些浓度与总浓度相比较低。然而，两种原位试验均未检测到玻璃厂土壤的毒性：V.未观察到fischer效应，也未观察到对L.大蒜然而，与参考土壤相比，垃圾填埋场土壤中的enchytraeid和线虫丰度和生物量有所减少，这意味着对土壤生物的原位毒性。原位生物利用度和负面影响的确认激发了对玻璃厂村庄人类风险的进一步研究。
The present study addresses toxicological properties of metal contaminated soils, using glassworks sites in south-eastern Sweden as study objects. Soil from five selected glassworks sites as well as from nearby reference areas were analysed for total and water-soluble metal concentrations and general geochemical parameters. A battery of biotests was then applied to assess the toxicity of the glassworks soil environments: a test of phytotoxicity with garden cress (Lepidium sativum); the BioTox™ test for toxicity to bacteria usingVibrio fischeri; and analyses of abundancies and biomass of nematodes and enchytraeids. The glassworks- and reference areas were comparable with respect to pH and the content of organic matter and nutrients (C, N, P), but total metal concentrations (Pb, As, Ba, Cd and Zn) were significantly higher at the former sites. Higher metal concentrations in the water-soluble fraction were also observed, even though these concentrations were low compared to the total ones. Nevertheless, toxicity of the glassworks soils was not detected by the twoex situtests; inhibition of light emission byV. fischericould not be seen, nor was an effect seen on the growth ofL. sativum. A decrease in enchytraeid and nematode abundance and biomass was, however, observed for the landfill soils as compared to reference soils, implyingin situtoxicity to soil-inhabiting organisms. The confirmation ofin situbioavailability and negative effects motivates additional studies of the risk posed to humans of the glassworks villages.
