摘要
随着工业的发展,土壤铬污染问题日益突出,对人体和环境产生巨大危害。了解铬在土壤环境中的迁移转化行为对于预测其变化趋势和控制环境污染具有重要意义。对土壤中铬的来源、价态、危害及其在土壤中的迁移转化作用进行了综述,并重点指出影响铬迁移转化的土壤p H值、有机质、氧化还原电位、土壤类型和微生物作用等因素的研究现状,以及就进一步研究土壤中铬迁移转化的方向进行了展望。
With the development of industry,the problem of Cr-pollution in soil has become serious. It is harmful to human body and environment. It is very important to understand the transformation behavior of Cr in soil for predicting its change tendency and control environmental pollution. This paper reviewed the source, valence, harmfulness and migration and transformation of chromium in soil. Research status on the factors such as the soil p H,organic matter,redox,soil type,and microbial action were pointed out. Finally,this study further proposed the further research direction for migration and transformation of chromium in in soil.
