新型灭螺药氯代水杨胺环境行为研究Ⅰ——土壤吸附和淋溶特性
Environmental behavior study of the new molluscicide LDSⅠ——Soil adsorption and leaching character
摘要
Abstract
To measure and evaluate the adsorption and leaching characteristics to a new molluscicide of salt of quinoid 2′, 5-dichloro-4′-nitrosalicylanilide (Hereinafter referred to as chlorosalicylicamide (LDS)) in three types of soil. The reports will be provided for drug registration. According to national standards of the People's Republic of China, the chemical pesticide environmental safety evaluation test guidelines of soil adsorption experiment and soil leaching method. The soil adsorption test results indicates that the adsorption constants and adsorption coefficient was 17.606 and 1 222.6 in moisture soil respectively. Adsorption rate in black and red soil were both more than 80%. Soil leaching test results indicates that Rf(The Rfsaid material in two phase distribution coefficient related values) in moisture soil was 0.158 while in black and red soil were both 0.085. According to the chemical pesticide environmental safety evaluation test guidelines, LDS was medium adsorption in moisture soil while more than 80% in black and red soil. LDS was not eas-ily to leach in moisture soil, which was not move in black and red soil. The conclusion is: within the red and black soil environment, in which pH value is relatively low, the adsorption ability of LDS is stronger and less mobility, which shows that new type of molluscicide of LDS has little effect on the environment.关键词
