气源性重金属污染物在土壤中的累积效果以及影响预测分析

On Cumulative Effect and the Impact Predictive Analysis of Air-borne Heavy Metal Pollutants in the Soil

通过气源性重金属在土壤中的累积效果分析表明,在考虑土壤中背景重金属的衰减时,其预测结果不能准确反映气源性重金属在土壤中的累积效果,考虑到成土过程与气源性重金属的输入时间差异较大,建议在对重金属的土壤累积分析时,可以不考虑土壤背景中重金属的衰减影响。

The cumulative effects of air- borne heavy metals in the soil analysis showed that,in considering the background of heavy metals in the soil attenuation,the predicted results do not accurately reflect the cumulative effect of air- borne heavy metals in the soil,taking into account the process of soil formation and gas derived heavy metal input time differences,it suggested that when a cumulative analysis of heavy metals in the soil,you cannot consider the decay of heavy metals in the soil background effect.
