1地表自然过程排汞研究进展及展望显示文摘地表自然过程排汞包括了自然源排汞过程和先前排放的汞沉降到地表后的再排放过程。已有证据显示,地表自然过程向大气的排汞量可能远大于人为活动直接向大气的排汞量。准确确定自然过程汞的释放通量,不仅对正确评价目前减少人为活动向大气排汞对全球环境汞污染的影响程度具有重要的意义,而且可为全球大气汞的减排政策的制定提供重要科学理论依据。本综述通过对国内外地表自然排放源相关文献的调研分析发现:由于缺少可靠的观测技术、对地表与大气间汞交换过程和机理的准确认识及大气汞沉降对地表自然排汞过程影响的认识还不清楚,因此目前还难以准确估算地表自然过程向大气的排汞量。近年来,随着技术手段的进步,已具备了开展地表自然排汞及先前排汞沉降后的再释放过程、机理和通量研究的可行性。地表自然过程排汞的研究将是汞的生物地球化学循环演化研究领域的前沿之一。冯新斌 付学吾 SOMMAR Jonas LIN Jery 商立海 仇广乐 2011生态学杂志2011,30,5:15
2Exchange flux of total gaseous mercury between air and natural water surfaces in summer season显示文摘The exchanges of mercury between surface and air are of significance in the biogeochemical cycling of Hg in the environment, but there are still few reliable data on air/surface exchange in aquatic systems. Field measurement campaigns over seawater surface at Kristineberg Marine Research Station (KMRS) and over Hovg?rds?n River surface at Knobesholm in southwestern Sweden were conducted to measure mercury flux using a dynamic flux chamber technique coupled with automatic mercury vapor-phase analyzers. Both sites show net emissions during summer time. Mercury fluxes measured over both river and seawater surfaces exhibit a consistently diurnal pattern with maximum fluxes during the daytime period and minimum fluxes during the nighttime period. At freshwater site, mercury flux is strongly correlated with the intensity of net solar radiation, and negatively correlated with relative humidity. A typical exponential relationship between mercury flux and water temperature was observed at freshwater measurement site. At seawater site, a strong correlation between mercury flux and intensity of solar radiation was obtained. The driving force of mercury emission from water surface to air is the super-saturation of dissolved gaseous mercury in aqueous phase.冯新斌 Jonas Sommar Katarina Grdfeldt OliverLindqvist 2002Science China Earth Sciences2002,45,3:10
