Recently I am researching about POLYCYCLIC AROMATIC-HYDROCARBONS; POLYCHLORINATED-BIPHENYLS PCBS; POLYBROMINATED DIPHENYL ETHERS; SURFACE SEDIMENTS; PAHS; MARINE; LAGOON; PBDES; SOILS, Saw an article supported by the . Published in SPRINGER in DORDRECHT ,Authors: Toan, VD; Quynh, TX; Huong, NTL. The CAS is 101-84-8. Through research, I have a further understanding and discovery of Diphenyl oxide. COA of Formula: C12H10O
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 n-ary sumation (6)PCBs, n-ary sumation (16)PAHs and n-ary sumation 7PBDE concentrations ranging from 4.73 to 36.34 ng g(-1) dw, from 3.57 to 84.39 ng g(-1) dw and from 4.49 to 12.49 ng g(-1) 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(DL-PCBs), TEQ (n-ary sumation 8PAHs) and TEQ (n-ary sumation 16PAHs) range from 4.6 to 10.4 ng kg(-1) dw, from 0.28 to 1.28 ng g(-1) dw and from 0.29 to 1.38 ng g(-1) dw, respectively. Ecological risks of S-EDCs range from very low to medium levels in the sediment of KimNguu river.
