英文摘要	The reductive dechlorination and behavior of p,p'-dichlorodiphenyltrichloroethane (p,p'-DDT) was investigated in a paddy soil. Treatment with 5% (w/w) metallic iron (Fe-0) resulted in sharp decrease of p,p'-DDT, whereas there was no extra effect when 2% (w/w) aluminum sulfate (Al-2(SO4)(3)) was added to the Fe-0 treatment. These results suggest that Fe-0 could effectively promote the reductive dechlorination of p,p'-DDT and its metabolites while Al-2(SO4)(3) did not show any effect on those processes. Furthermore, p,p'-DDT and its daughter compounds inhibited holistic soil respiration greatly at first but could be metabolized by certain species of indigenous microorganisms after a period of adaptation time in the soil. When treated with Fe, the polluted soil produced much less CO2 while the addition of Al-2(SO4)(3) counteracted its negative effect to much extent. (c) 2005 Elsevier Ltd. All rights reserved.
