中国重金属污染耕地土壤安全利用存在问题与建议
Problems and Suggestions on Safe Utilization of Heavy Metal(loid)-contaminated Farmlands in China
摘要
Abstract
Heavy metal(loid)s-contaminated farmlands exist commonly in China,which is an urgent agricultural and environmental problem to be solved.According to heavy metal levels,application of low accumulation crops and soil amendments,as well as the utilization of agricultural managements are the current safe utilization technologies of contaminated farmlands.It was pointed out that the insufficient attention of farmland pollution sources,unclear relationship between soil pollution and crop safety,as well as the potential risk of soil amendments application and restriction of heavy metal(loid)s-low accumulation crops,were the main issues during the process of safe utilization of contaminated farmland.The improvements of evaluation standard,prevention system and safe utilization technologies of contaminated soils are suggested to guarantee the safety of crops production.关键词
