| Abstract | Air-soil exchange is a key process controlling the fate of persistent organic pollutants (POPs). However, the "sink effect" of soil for POPs in Tibetan pasture has not been dear. In NamCo, in the central Tibetan Plateau (TP) where the land is covered by grass, a modified passive air sampler (PAS) (thickness: 2 cm) was tested. Using the PAS, the atmospheric gaseous phase organochlorine pesticides (OCPs) at 11 heights from close-to-surface (2 cm) to 200 cm above ground, in summer and in winter, were measured. Concentrations of OCPs in summer were higher than those in winter. Both in summer and winter, atmospheric concentrations of OCPs decreased with decreasing height from 200 to 2 cm, indicating that OCPs were tiding deposited from air to soil. Air deposition of OCPs was possibly driven by wind speed. Furthermore, based on air OCPs at 0-3 cm near the surface, the interface exchange of OCPs between air and soil was studied by the fugacity method. The results showed that pastural soil in the TP was a "sink" of OCPs even in summer. The mean deposition fluxes of alpha-HCH, gamma-HCH and o,p'-DDT were 0.72, 0.24 and 0.54 pg/h/m(2), respectively, and it was estimated that the level of these pollutants in the soil will double every 24, 66 and 206 years, respectively. This study will contribute to the further understanding of global cycling of POPs in different land covers. (C) 2016 Elsevier B.V. All rights reserved. |
