除草剂在土壤—植物系统中的环境行为与毒性效应

Environmental Behaviors and Toxic Effects of Herbicides in Soil-plant System

介绍了除草剂在土壤—植物系统中的环境行为、生态毒性效应及与其他污染物的交互作用。认为除草剂的环境行为对其生态毒性具有重大的影响。大部分除草剂在土壤环境中被降解或流失。残余除草剂对植物的毒害表现在光合作用、生长发育和吸收上 ;

The environmental behaviors and ecotoxic effects of herbicides and their interactions with other pollutants were reviewed. It was believed that the environmental behaviors of herbicides could highly affect their ecotoxicity. Most herbicides were degraded and run off in soil. The toxicity of herbicide residues exerted in the photosynthesis, growth and uptake of plants and in the inhibition of soil organisms.
