Comparative Degradation Study of Lambda Cyhalothrin in Soils from Athi River And Kwale Areas in Kenya
Keywords:
L-Cyhalothrin; Soils; and pH.Abstract
Impacts of the physicochemical properties of different soils were studied through degradation analysis of L-Cyhalothrin (lambda-Cyhalothrin). The effect of dissimilar soil properties was determined through proportionate application of the pesticide to selected soil samples over its expected degradation half-life period. L-Cyhalothrin showed higher affinity to soils from Kwale than soils Athi River Soil. Over the 40 day period of the study, the soils Kwale region adsorbed twice more L-Cyhalothrin than soil from Athi River area. About 65% of initial concentration of L-Cyhalothrin was adsorbed in Kwale soil and 33% in Athi river soil. The degeneracy was particularly due to the physicochemical properties of the soils.
