英文摘要	The levels of eight organophosphate esters (OPEs) were analyzed in air and soil samples collected at Ny-Alesund and London Island, Svalbard during the Chinese Scientific Research Expedition to the Arctic during 2014-2015. The concentrations of total OPEs (Sigma OPEs) ranged from 357 pg/m(3) to 852 pg/m(3) in the air and from 1.33 ng/g to 17.5 ng/g dry weight (dw) in the soils. Non-Cl OPEs accounted for 56 +/- 13% and 62 +/- 16% of Sigma OPEs for the air and soil, respectively. Tris(2-chloroethyl) phosphate (TCEP) was the dominant compound in the air, with an average concentration of 180 +/- 122 pg/m(3). Triphenyl phosphate, tri(1-chloro-2-propyl) phosphate, and TCEP were the most abundant OPEs in the soils, with mean values of 1.77, 2.13, and 1.02 ng/g dw, respectively. Compared with the levels of polybrominated diphenyl ethers found in Arctic regions in previous studies, OPEs showed significantly higher concentrations, thereby indicating the large production and wide usage of OPEs globally. In addition, the fugacity fraction results indicated that net deposition from air to soil was dominated in the area. Overall, the occurrence and distribution of OPEs in the air and soils in the Arctic region indicated that OPEs can undergo long-range atmospheric transport and accumulate in remote regions.
