Research on pollution of Phthalate este (PAES) in water of Kim Nguu river, Hanoi

Abstract

    This research presents the results of a review of typical PAEs (6 PAEs indicator) of PAEs group inwater samples of Kim Nguu River, Hanoi. Results show that there is a wide range of PAEscontamination. The Σ6PAE concentration in the water sample ranged from 2.73 to 377.02 μg/l inApril 2018 and from 2.70 to 376.92 in October 2018. At most sampling sites, DEHP, DEP and DBPhad an mean percentage greater than the remaining PAEs. The level of environmental riskincreases from DBP (very low risk) to DEP (low risk) and DEHP (low to medium risk). Because ofthe high concentration of PAEs in the environmental components, further studies on thecontamination of PAEs in the Kim Nguu need to continue.
