摘要：DDT (1,1,1-Tricholor-2,2-bis(chlorophenil)ethane) and its two derivatives, DDD (1,1- Dicholor-2,2-bis(chlorophenil)ethane) and DDE (1,1-Tricholor-2,2-bis(chlorophenil)-ethylene) were identified in the coastal sediment of Citarum Estuary, Jakarta Bay. Eight stations of the sediment sampling were designed in order to obtain the changing of their concentrations adjacent to the estuary as possible input. Sediment samples were collected in the surface layer within a less than 5 cm depth. In addition to pesticides, texture of sediment and total organic carbon were analyzed. Generally, fine fractions (silt and clay) were predominant grain-size of the sediment ranging 21 – 35,8 % and 17,6 – 65,6 %, respectively, while total organic carbon (TOC) ranged from 0,30 – 1,49 %. Concentrations of p’,p’-DDT varied from 0,621 – 1,187 ppb, concentrations of p’,p’-DDD ranged from 0,176 – 2,153 ppb and concentrations of p’,p’- DDE were from 0.181 – 2,254 ppb. The occurrence of total DDT (Σ DDT+DDD+DDE) tended to correlated positively to the fine fraction indicating as transport agent. DDD and DDE as DDT metabolites were formed by biological and chemical processes within predominantly aerobic condition.
