Distribution and degradation of SAS in soil environments in the Taihu Lake region

Abstract

Abstract: Soil samples of different soil types under different land use patterns and environmental impacts were collected in Wuxian City in the Taihu Lake region.The contents of SASwere determined by Azure Acolorimeter.Degradation of LASwas studied in the water and soil mediums by using laboratory incubation.The SASconcentration in the studied soils ranged from 2 to 10mg·kg^-1 ,varied with soil conditions.Profile distribution of SASshowed decreasing trend down to the soil bottom,where 0.7mg·kg^-1 of SASwas still detected.The degradation of LASin three dominant types of paddy soils obeyed the primary reaction equation like that of soil organic matter with the half residence time in range of 9～16 days.The data indicates the relative accumulation of SASin the soils in the Taihu Lake region and longer residence of such synthetic organic compounds in the soil environments.

Key words: Organic pollutant, SAS, Degradation, Soil environment, Taihu Lake region
