Endocrine Disrupting Compounds (EDCs) in Surface Waters of the KimNguu River, Vietnam

Abstract

This research presents the assessment of contamination status, congener profiles and ecological risk of selected endocrine disrupting compounds (S-EDCs) in surface water from KimNguu River, Hanoi. Selected EDCs compose polychlorinated biphenyls (PCBs), phthalate esters (PAEs) and polybrominated diphenyl ethers (PBDEs). Water sampling and chemical analyses were carried out in collected water samples in dry season (April) and wet season (October) in 2018. Results pointed out a significant contamination with ∑6PCBs, ∑6PAEs and ∑7PBDE concentrations ranging from 1.89 to 8.93 ng/L, from 2.78 to 412.27 ng/L and from 1.92 to 7.08 ng/L, respectively. Composition analyses indicated the predominance of PCB52, PCB118, DEP, DEHP, DBP, BDE-47 and BDE-99. Ecological risks of S-EDCs range from very low to medium levels in the surface water of KimNguu River.
