生物炭在土壤农药修复中的应用研究进展

Application of Biochar in Soil Pesticide Remediation

摘要: 农药因其可以积累到人类和其他生物体内而受到了人们的关注，为了探究生物炭在农药修复中的作用，本文阐述了生物炭用于修复持久性有机农药的作用，并针对农药的种类及其对生命形式的危害详细介绍了生物炭的生产、特点及应用。通过向农药中添加生物炭具有以下优点：(a) 提高土壤持水能力；(b) 改善土壤中的通气条件；(c) 为微生物的生长提供栖息地，从而促进微生物群落的代谢活动和农药降解。本文还阐述了利用生物炭修复农药存在的问题及今后的研究方向。

Abstract: Pesticides have attracted people’s attention because they can be accumulated in human beings and other organisms. In order to explore the role of biochar in pesticide remediation, this paper expounds the role of biochar in the remediation of POPs, and introduces the production, charac-teristics and application of biochar in detail according to the types of pesticides and their harm to life forms. Adding biochar to pesticides has the following advantages: (a) improving soil water holding capacity; (b) improving aeration conditions in the soil; (c) providing habitat for the growth of microorganisms, so as to promote the metabolism of microbial community and pesticide deg-radation. In addition, the problems and future research directions of biochar for pesticide reme-diation were also discussed.
