| 摘 要： | 重金属是农业生态系统中一类具有潜在危害的化学污染物,它不能为土壤微生物所分解,但可被生物体富集,并且可以转化成毒性更大的甲基化合物。因此,土壤受重金属污染将直接影响到土壤中生物体的重金属离子含量,并进而影响到人体健康和土壤生态系统的平衡。

| Abstract: | The heavy metal is chemical pollutant of having hide harm. It can not be resolved by microorganisms. But it can be gathered by living things and transformed into more poisonous methyl chemical compound. So when the soil is polluted by heavy metal it effect the content of heavoy metal in soil and the mankind health and the balance of the soil ecology. |
