The main aim of this short review was to assess the effect of test medium on the bioavailability of metals to the soil invertebrate Folsomia candida and the barley plant Hordeum vulgare. Solution-only exposures and sand-solution media were suitable media with control survival of > 80%. Comparing toxicity and accumulation data, LC and/or EC values as well as internal concentrations of cadmium (Cd) and copper (Cu) were similar in the tests with different porewater composition for springtails and barley plants. Similar results for toxicity and bioaccumulation of Cd and Cu using different test substrates, suggest the importance of physiological handling of the effects by the organisms rather than the influence of test medium composition.
本次简短综述的主要目的是评估测试介质对土壤无脊椎动物 Folsomia candida 和大麦植物 Hordeum vulgare 中金属生物利用度的影响。仅溶液暴露和沙-溶液介质是合适的介质，控制存活率>80%。比较毒性和积累数据，跳虫和大麦植物的不同孔隙水组成的试验中 LC 和/或 EC 值以及镉 (Cd) 和铜 (Cu) 的内部浓度相似。使用不同测试底物时 Cd 和 Cu 的毒性和生物累积的相似结果表明，生物体对影响的生理处理比测试介质组成的影响更为重要。
