The paper presents the first comprehensive survey of congener profiles (12 congeners) of polybrominated diphenyl ethers (PBDEs)in core sediment samples (63Um) covering seven sites in Sundarban mangrove wetland (India).Gas-chromatographic analyses were carried out in GC -Ms/Ms for tri-to hepta- brominated congeners. Results pointed out a non-homogenous contamination of the wetland with Sigma 12 PBDE values ranging from 0.08 to 29.03 ng g-1, reflecting moderate to low contamination closely in conformity to other Asian aquatic environments. The general order of decreasing congener contribution to the total load wasBDE 47 99 100 154,similar to the distribution pattern worldwide. Although tetrabromodiphenyl ether BDE 47 was found in all samples followed by hexabromodiphenyl ether BDE-154, they were not necessarily the dominant congeners. No uniform temporal trend on PBDE levels was recorded probably due to particular hydrological characteristics of the wetland and/on non-homologous inputs from point sources (untreated municipal wastewater and local industries, electronic wastes from the dump sites, etc.) of these compounds. Because of the propensity of PBDEs to accumulate in various compartments of wildlife and human food webs, evaluation of biological tissues should be under taken as a high priority.
