| 摘 要： | 污泥农用是解决城市污泥出路较为合理的途径.但由于含较高量的重金属，它的应用受到限制.研究发现，进入土壤的重金属在不同的土壤类型、不同的土壤条件下，形态分布各不相同，而不同形态的重金属对植物的有效性和毒性也不相同，本文试图对土壤中影响重金属形态分布的因素及机制作一综述.

| Abstract: | Sewage sludge utilized on agricultural lalld as fertilizer is a reseanable treatment, but the high heavy metal content restricts the expansion of this way. It is found that the fraction distribution, the availability and toxicity of heavy metals are different in different soil types and different soil conditions. This paper tries to summarize the factors and mechanism affecting the fraction distribution of heavy metals in soil. |
