Effect of Environmental Conditions on Degradation of Anilofos in Soil
-
Abstract
The degradation rate of anilofos in soil varied with the environmental conditions. When tempera- ture was 20, 30, 40℃ separately, the degradation rates of anilofos was 10. 4% , 26. 7% and 37. 6% , respec-tively; The degradation rate increased from 45. 0% to 68. 4% when soil water content varied from 30% to 110%. The half-lives of anilofos was 11 d and 15 drespectively, in soils with organic mat ter contents 3. 35% and 0. 55%. When soil pH values were 6. 01 and 7. 98, the half-lives of anilofos were 22d and 15d, respec-tively. These results indicated that organic matter,water contents and temperature of soil enhanced anilofos degradation and the degradation rate of the chemical in alkaline soil was higher than in acid soil.
