这项研究的目的是评估金属（锌、铅和镉）的总含量和可溶性形式以及受到与开采锌矿和铅矿有关的强大人类压力的土壤的毒性。研究地区位于布科诺（波兰）Bolesław矿山和冶金厂附近。土壤总镉浓度为0.29 ~ 51.91 mg，总锌浓度为7.90 ~ 3614 mg，总铅浓度为28.4 ~ 6844 mg kg - 1土壤d.m。重金属在1 mol dm−3 NH4NO3中的溶解度，锌为1 ~ 49%，镉为5 ~ 45%，铅<1 ~ 10%。在1 mol HCl dm−3中，所研究的金属的溶解度要高得多，并且根据收集位置的不同，锌的溶解度为45% ~ 92%，铅的溶解度为74% ~ 99%，铅的溶解度为79% ~ 99%。重金属在1 mol dm−3 NH4NO3中的溶解度比1 mol HCl dm−3中的溶解度低与此有关，硝酸铵萃取力低，可用于测定重金属的生物可利用（活性）形态。使用Phytotoxkit和Microtox®两种检测方法对土壤样品进行毒性评估。白刺萌发指数在22% ~ 75%之间，莴苣萌发指数在28% ~ 100%之间，糖高粱萌发指数在10% ~ 28%之间。根据研究的土壤样品，费氏弧菌的发光抑制率为20 - 96%。受试菌的敏感性依次为：S. saccharatum > S. alba = V. fischeri > L. sativum。金属总含量和可溶性含量与费雪菌的发光抑制作用和糖蜜菌的根生长抑制作用呈显著正相关（p≤0.05）。观察到的总体趋势是，生物试验测定的金属毒性随着土壤中有效金属含量的增加而增加。所有的土壤样本都被归类为毒性III类，这意味着它们是有毒的，存在严重的危险。在土壤质量评价和土壤管理方面，生物试验是对化学分析的良好补充。
This research is aimed at assessing the total content and soluble forms of metals (zinc, lead and cadmium) and toxicity of soils subjected to strong human pressure associated with mining of zinc and lead ores. The research area lay in the neighbourhood of the Bolesław Mine and Metallurgical Plant in Bukowno (Poland). The study obtained total cadmium concentration between 0.29 and 51.91 mg, zinc between 7.90 and 3,614 mg, and that of lead between 28.4 and 6844 mg kg−1 of soil d.m. The solubility of the heavy metals in 1 mol dm−3 NH4NO3 was 1–49 % for zinc, 5–45 % for cadmium, and <1–10 % for lead. In 1 mol HCl dm−3, the solubility of the studied metals was much higher and obtained values depending on the collection site, from 45 to 92 % for zinc, from 74 to 99 %, and from 79 to 99 % for lead. The lower solubility of the heavy metals in 1 mol dm−3 NH4NO3 than 1 mol HCl dm−3 is connected with that, the ammonium nitrate has low extraction power, and it is used in determining the bioavailable (active) form of heavy metals. Toxicity assessment of the soil samples was performed using two tests, Phytotoxkit and Microtox®. Germination index values were between 22 and 75 % for Sinapis alba, between 28 and 100 % for Lepidium sativum, and between 10 and 28 % for Sorghum saccharatum. Depending on the studied soil sample, Vibrio fischeri luminescence inhibition was 20–96 %. The sensitivity of the test organisms formed the following series: S. saccharatum > S. alba = V. fischeri > L. sativum. Significant positive correlations (p ≤ 0.05) of the total and soluble contents of the metals with luminescence inhibition in V. fischeri and root growth inhibition in S. saccharatum were found. The general trend observed was an increase in metal toxicity measured by the biotest with increasing available metal contents in soils. All the soil samples were classified into toxicity class III, which means that they are toxic and present severe danger. Biotest are a good complement to chemical analyses in the assessment of quality of soils as well as in properly managing them.
