To understand the role of vegetation and soil in regulating atmospheric Hg0, exchange fluxes isotope signatures Hg were characterized using a dynamic flux bag/chamber at atmosphere-foliage/soil interfaces Davos-Seehornwald forest, Switzerland. The foliage was net Hg0 sink took up preferentially light isotopes, consequently resulting large shifts (-3.27‰) δ202Hg values. served mostly as sources with higher emission from moss-covered soils than bare soils. negative shift Δ199Hg values efflux...
Abstract Antimony (Sb) is a toxic heavy metal, and PM 2.5 ‐bound Sb (Sb PM2.5 ) in the air impacts human health via inhalation pathways. In this study, we analyzed multiyear measurements of ambient Beijing to characterize its spatiotemporal distributions, identify main sources, predict future trends. The results show that has been decreasing with fluctuations from 2005 2012 decreased rapidly after 2013, which was likely result government's enhanced pollution control plan targeted sources...
The geochemical characteristics of atmospheric deposition can help trace the origin and assess impacts pollutants. Northeast China has always been a region seriously affected by sandstorms. This study aims to explain potential source sandstorms in Gannan County, Heilongjiang Provence, collecting dust analyzing geochemistry one year where there is no significant industrial or anthropogenic pollution. Input fluxes show that Zn Mn were more prevalent (36.7 g·hm−2·a−1 77.93 g·hm−2·a−1,...
In order to study the changes of soil carbon pool and enzyme activities after saline land remediation, carbon, protease, catalase, urease phosphatase contents in samples plant collected from project area were analysed.After 2 4 years saline-alkali total content 0-20cm surface decreased significantly by 24-63%, organic 0-10 cm 32-35%, 10-60 increased 23-42%.The inorganic profile 21-72%.In range 60~100 cm, it 32~60%.At early stage catalase gradually with increase depth.The density remediation...
