Dissipation, binding, and degradation of 14C-p, p'-DDT in Indonesian soils were studied under field conditions in Pasar Jumat (lowland) and Cipanas (highland). A study on 14C-p, p'-DDE was also conducted at Pasar Jumat. The observed time for 50% loss of radiocarbon was 25, 9 and 12 weeks for DDT lowland, DDT highland and DDE respectively. The corresponding overall half-lives of dissipation were 236, 159 and 228 days respectively. Bound residue formation progressed slowly to 7% in lowland. After one year, total 14C residues from DDT remaining in lowland and highland soils were 34.3% and 20.4% respectively. Degradation of p,p'-DDT in lowland was faster than in highland and the major degradation product was p,p'-DDE. In the DDE experiment no metabolite was found. It is concluded that both DDT and DDE dissipate from tropical Indonesian soils at much faster rates than those reported for temperate zones. |
