It has been shown that soil pollution with heavy metals (copper, nickel) lead to negative changes in parameters characterizing potential biological activity of soil (nitrogen-fixation, breath, invertase activity, bacteria and fungi count). More profound changes were observed in sandy soil compared to loamy soil. A direct relationship of these effects with the content of mobile forms of heavy metals in soil has been established. For the comparative and prognostic investigation of the danger of soil pollution with heavy metals it has been suggested to use a coefficient of differences in the content of mobile forms and a coefficient of biological effect.
研究表明，土壤中重金属（铜、镍）污染会导致表征土壤潜在生物活性的参数（固氮、呼吸、转化酶活性、细菌和真菌数量）发生负面变化。与壤土相比，沙质土壤中观察到的变化更为显著。已确定这些影响与土壤中重金属可移动形态的含量直接相关。为了对土壤重金属污染危害进行比较和预后调查，建议使用可移动形态含量差异系数和生物效应系数。
