Abstract

Abstract: To provide a scientific basis for environmental risk assessment of metazachlor，the environmental fates of metazachlor，including photodegradation，volatilization，absorption，mobility，degradation in soil，were studied according to "Experimental Guideline for Environmental Safety Evaluation of Chemical Pesticides". Results showed that photolysis and volatilization were not important fate of metazachlor on soil surface; metazachlor was moderate to highly mobile in soil and did not adsorb strongly to solid matrices; the half-life of metazachlor in soil varied depending on soil types and environmental conditions （aerobic and anaerobic in water），and was estimated to be 4-96 days. However，metazachlor has the potential to pollute ground and surface water due to its relatively high mobility and long half-life in clay.

Key words: metazachlor, soil, environmental fate
