农田土壤重金属污染及污染修复技术研究进展

Analysis of Heavy Metal Pollution of farmland Soil and Advances of Soil Pollution Restoration Technology

指出了我国农田土壤重金属污染情况严重,约有1/5的耕地受到重金属的污染。从污水灌溉、大气沉降、固体废弃物、农用物资施用等方面探讨了农田土壤重金属的主要来源,分析了土壤重金属污染修复技术,包括物理修复、化学修复、生物修复等方法。

Heavy metal pollution, Which causes soil quality decrease, crops contamination and threats to human health,has become one of the most serious environmental problems today in China. There are about one fifth of arable land polluted by heavy metals. Most heavy metal pollution in soils are caused by human activity , such as sewage irrigation, atmospheric deposition, municipal solid waste and soil cultivation. There are many remedy technology used for heavy meatal pollution, such as physical remediation , phytoremediation and bioremediation. Together with the above methods to seal with the heavy metal pollution will be the developing direction of pollution remedy technology.
