摘　　要：洛克沙胂具有提高饲料利用率、抑制有害菌和促进生长的作用,因此在畜禽养殖业中的应用较为广泛,然而由于其在动物体内吸收量极低,绝大部分随动物粪便和尿液排出体外,若处理不当会导致土壤和地下水环境出现砷污染现象。近年来,我国畜禽养殖业发展较为迅速,但是有些畜禽养殖区已经暴露出严重的砷污染问题。笔者对畜禽养殖砷污染调查研究、洛克沙胂在环境中的转化和吸附作用以及洛克沙胂污染的治理等方面进行了综述。The roxarsone can improve feed utilization,inhibit harmful bacteria and promote the growth,so it is widely used in livestock and poultry industry.However,most of them were excreted with animal feces and urine due to its low uptake,which can lead to arsenic contamination in soil and groundwater if improper handling appears.Recent years,the livestock and poultry industry has been rapidly developed,a large proportion has not harmless treatment for solid-liquid waste,but stack in open environment casually.The investigation on arsenic contamination in livestock and poultry industry,transformation and adsorption of roxarsone in environment,control of roxarsone contamination were reviewed in the study.
