| Abstract/Contents: | "The fumigant 1,3-dichloropropene (1,3-D) is considered a major replacement to methyl bromide, which is to be phased out of use in the United States by 2005. The main purpose of this study was to evaluate soil-water partitioning of 1,3-D in two California agricultural soils (Salinas clay loam and Arlington sandy loam). The partition coefficients (Kd and Kf) were determined by directly measuring the concentration of 1,3-D in the solid phase (Cs) and aqueous phase (Cw) after batch equilibration. In the Salinas clay loam, the Kf of cis-1,3-D in adsorption and desorption isotherms was 0.47 and 0.54, respectively, with respective values of 0.39 and 0.49 for trans-1,3-D. This slight hysteric effect suggests that a different range of forces are involved in the adsorption and desorption process. Since n was near unity in the Freudlich equation, the Freudlich isotherms can also be approximated using the linear isotherm. At 25°C, the Kd of the 1,3-D isomers in both soils ranged from 0.46 to 0.56, and the Koc (organic matter partition coefficient) ranged from 58 to 70. The relatively low Kd values and a Koc that falls within the range of 50-150, suggest that 1,3-D is weakly sorbed and highly mobile in these soils. Understanding the sorption behavior of 1,3-D in soil is important when developing fumigation practices to reduce the movement of 1,3-D to the air and groundwater." |
