摘要
随着工业的快速发展、农药及化肥的广泛使用,农田土壤重金属污染越来越严重,进而对农产品的质量安全构成严重威胁,因此,研究农田土壤重金属污染对农产品安全的影响具有重要意义。本文论述了农田土壤重金属污染物的主要来源和现状,以及土壤重金属污染对生态环境和人体健康构成严重威胁,为提升农田土壤环境质量和建立农产品质量安全体系提供理论和现实依据。
With the rapid development of industry,and the wide use of pesticides and fertilizers,farmland soil heavy metal pollution is more and more serious,that poses a serious threat to security and quality of agricultural products.So the study of farmland soil heavy metal pollution status is important with agricultural product quality safety.The paper discusses main source of the farmland soil heavy metal pollution and current situation,and the harm of soil heavy metal polluhon ot agncultural products satety.Because Heavy metal pollution is easy to accumulative total through the lood chain in the plants,animals,and the human body,so serious threat to the ecological environinent and human health.To improve farmland soil environment quality and the establishment of agricultural product quality security system provide theoretical and practical basis.
