AB  - Sorptive processes are important parameters affecting the mobility, availability 
      and fate of persistent organic pollutants (POPs), such as toxaphene, in aquatic 
      systems. The sorption and desorption behaviors of the B7-1450, a stable toxaphene 
      congener in environment, on marine sediment was studied under different 
      temperature and salinity conditions to better understand the B-1450 distribution 
      in estuarine systems. The data were fitted to different sorption models to 
      characterize sorption behaviors by evaluating sorption coefficients and 
      sequestrated fraction of B7-1450 on sediments. High carbon-normalized sorption 
      coefficients (Koc) of the B7-1450 were observed with values ranging from 3.2x104 
      to 6.0x104 mL g(-1) under experimental conditions. The data showed an increase of 
      B7-1450 sorption coefficients with the salinity and a decrease with temperature. 
      These investigations indicate that B7-1450 is three times more sequestred on 
      sediments in cold (2 degrees C, 30 psu) than in warm marine conditions (20 degrees C, 30 psu). 
      These results suggest that the mobility and bioavailable of B7-1450 or other POPs 
      from the sediments could be less important in cold marine comparatively in warm 
      marine and warm freshwater media. As a result of climate changes, the warming of 
      mid and high latitudes coastal waters could enhance the mobility of POPs.
