This research presents the assessment of seasonal variation, accumulation pattern and ecological risk of selected endocrine disrupting compounds (S-EDCs) in sediment samples covering six sites in KimNguu river, Hanoi, Northern area of Vietnam. Selected EDCs compose polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and polybrominated diphenyl ethers (PBDEs). Sediment sampling was carried out in dry season (April) and wet season (October) in 2018. Results pointed out a significant contamination with ∑PCBs, ∑PAHs and ∑PBDE concentrations ranging from 4.73 to 36.34 ng g dw, from 3.57 to 84.39 ng g dw and from 4.49 to 12.49 ng g dw, respectively. Composition analyses indicated the predominance of PCB 138, PCB 153, M-PAHs (Middle molecular weight PAHs: BaA, Chr, Pyr, Flt), BDE-47, BDE-99 and BDE-209. The values of TEQ, TEQ and TEQ range from 4.6 to 10.4 ng kg dw, from 0.28 to 1.28 ng g dw and from 0.29 to 1.38 ng g dw, respectively. Ecological risks of S-EDCs range from very low to medium levels in the sediment of KimNguu river.
本研究评估了越南北部河内金尼罗河六个地点的沉积物样本中选定的内分泌干扰化合物（S-EDCs）的季节性变化、积累模式和生态风险。选定的 EDCs 包括多氯联苯（PCBs）、多环芳烃（PAHs）和多溴二苯醚（PBDEs）。沉积物采样分别于 2018 年的旱季（4 月）和雨季（10 月）进行。结果表明，∑PCBs、∑PAHs 和∑PBDE 的浓度存在显著污染，范围分别为 4.73 至 36.34ng g dw、3.57 至 84.39ng g dw 和 4.49 至 12.49ng g dw。组成分析表明，PCB 138、PCB 153、M-PAHs（中分子量 PAHs：BaA、Chr、Pyr、Flt）、BDE-47、BDE-99 和 BDE-209 占主导地位。TEQ、TEQ 和 TEQ 的值分别为 4.6 至 10.4ng kg dw、0.28 至 1.28ng g dw 和 0.29 至 1.38ng g dw。金尼罗河沉积物中的 S-EDCs 生态风险从低到中等水平不等。
