英文摘要

The concentrations of trifluoroacetic acid (TFA) were measured in urban landscape waters, tap water and snows in Beijing, China in 2012. Compared with the 2002 measurements, a 17-fold increase from 23-98 ng L-1 to 345-828 ng L-1 was observed for TFA concentrations in urban landscape waters, and an obvious increase from not detected (n.d.) to 155 ng L-1 occurred to TFA in tap water. By flux estimation between air and water interface, the remarkable increase of TFA was attributable to dry and wet deposition. The quantitative water-air-sediment interaction (QWASI) model simulated TFAs in various environmental media and showed that, over 99% of TFA distributed in water bodies. Our results recommend that measures are needed to control the increase of TFA in China. (C) 2014 Elsevier Ltd. All rights reserved.
