title: Distribution of DDT in a typical DDT waste contaminated site.
abstract: Serious pollution was found in the soil under a historically DDT workshop and the highest level of (summation operator)DDT was 2682.86 mg/kg. The vertical distribution of DDT shows that the levels of DDT decreased significantly with increase of depth, which mainly because the infiltration of rainwater was inhibited by the cement or brick surface. The DDT polluted soil area was 6,814 m(2) and the polluted soil volume 4,398 m(3) above 10 mg/kg. The ratio of (DDE + DDD) to DDT showed that part of the p,p'-DDT was degraded to DDD and DDE in the soil.
