中文摘要：

农药、重金属已成为当今农业生态系统中重要的污染物质,国内外科学家对其进行了大量卓有建树的研究,特别是在土壤-植物系统中的研究受到较多关注。通过就农药和重金属对土壤微生物、土壤动物、土壤酶活性和植物的生理生化指标的影响进行的综合分析和阐述,系统剖析了其产生毒害机理和影响的因素,在此基础上提出今后相关研究中有待加强的重点,包括农药对非靶标生物毒害机理、农药降解中间产物的环境风险以及农药和重金属的迁移转化机理等。

英文摘要：

Pesticides and heavy metals beeing considered as serious pollutants in agro-ecosystem,it had been studied massively over the world,especially in soil-plant system.The impact of pesticides and heavy metals on soil microbes,soil animals,soil enzymatic activity,and physiological and biochemical characters of plant were analyzed and discussed in this review,as well as their toxicological mechanism and influencing factors.Based on above,toxicological mechanism of pesticides on non-target,environmental risk of pesticides degradation products,and transformation mechanism of pesticides and heavy metals in soil-plant system were proposed as key areas in further study.
