中文摘要：

为了解氯溴虫腈在土壤中的转化归趋,开展了其在土壤中的降解、吸附、迁移等环境行为研究。结果表明：氯溴虫腈在东北黑土、北京黄棕土、山西棕土中的降解半衰期分别为19.8d、24.8d和21.0d,属于易降解农药。氯溴虫腈在3种土壤中的吸附规律符合Freundlich吸附等温线方程,有机碳吸附常数（Koc）均大于20000。氯溴虫腈东北黑土和北京黄棕土中的Rf值分别为0.125和0.25,在山西棕土中山西棕土的Rf值为0.5。氯溴虫腈在北京黄棕土和东北黑土中表现为易土壤吸附,不易移动,在山西棕土中表现为易土壤吸附,中等移动。

英文摘要：

The degradation, adsorption and mobility of brochlorfenapyr in different soils were studied. The results showed that the degradation half-lives of brochlorfenapyr were 19.8 d, 24.8 d and 21.0 d in black soil of northeast, yellow-brown soil of beijing and brown soil of shanxi respectively, the sorption isotherm could be well described by Freundlich equation. Adsorption coefficient（Koc） of brochlorfenapyr on three kinds of soils were more than 20 000. The value of Rf were 0.125, 0.25 and 0.5 respectively. The results of adsorption and mobility of brochlorfenapyr display easy-adsorption and difficult-mobile in black soil of northeast and yellow-brown soil of Beijing, easy-adsorption and mid-mobile in brown soil of shanxi.
