Methods: DNA damage was measured by the loss of fluorescence after DNA binding to ethidium bromide and by the increased DNA mobility in agarose gel electrophoresis.

方法：通过DNA结合溴乙锭后的荧光损失和DNA琼脂糖凝胶电泳的迁移率来测定dna的损伤程度。

The mobility, the bioavailability and the toxicity of heavy metals in the soil depend on their specific chemical forms and on their binding state.

土壤中重金属的赋存形态决定其在土壤中的迁移性、生物可利用性以及毒性。
