摘要
Organophosphate esters (OPEs) are alternatives to polybrominated diphenyl ethers, often used as flame-retardants and plasticizers. There are few reports of OPEs in river water. This study focused on the occurrence and spatial distribution of 11 OPE congeners and one synthetic intermediate triphenylphosphine oxide (TPPO) in 40 major rivers entering into the Bohai Sea. Total OPEs ranged from 9.6 to 1549 ng L(-1), with an average of 300 ng L(-1). Tris(1-chloro-2-propyl) phosphate (TCPP) (4.6-921 ng L(-1), mean: 186 ng L(-1)) and tris(2-choroethyl) phosphate (TCEP) (1.3-268 ng L(-1), mean: 80.2 ng L(-1)) were the most abundant OPEs and their distribution patterns are similar, indicating the same source (r = 0.61, P < 0.05) and the influence of large production and consumption of chlorinated OPEs in the region. Priority should be given to TCPP, PCEP and TPPO due to their high concentrations in the rivers and potential threat to aquatic organisms.
