  • Title: Estimation of OCDD degradation rate in soil.
    Author: Zhao XR, Zheng MH, Zhang B, Qian Y, Xu XB.
    Journal: J Environ Sci (China); 2005; 17(6):981-3. PubMed ID: 16465891.
    Abstract:
    The current concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were determined in soils contaminated with Chinese technical product sodium pentachlorophenate (Na-PCP). The estimated half-life of octachlorodioxin (OCDD) was about 14 years in contaminated soils based on the local historical record and mass balance calculation during the past 43 years (1960-2003). The isomer profiles remained the same regardless of paddy field soil or riverbank soil. The results indicated that the congener-specific information was efficient in estimating the PCDD/Fs fate in contaminated soils.
