Evaluation of pbde residue in sediment in Hochiminh city and solution proposed

Abstract

    Total PBDE residues are found in sediment at a significant level in Hochiminh city. Total PBDE concentration in the centre, suburban of Hochiminh city and Saigon-Dongnai estuary ranged from 54,5 - 119,0 ng/g; < 0,02 - 10,63 ng/g and < 0,02 - 0,065 ng/g, respectively. The long-time release of PCB in sediment in Hochiminh city is observed. Based on the PBDE residue, glycolate method to treat PBDE in sediment and one group of environmental management solution are proposed.
