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 congenerspecific information was efficient in estimating the PCDD/Fs fate in contaminated soils. 收起<<
