Abstract:Twenty-five fog/cloud water samples were collected at the weather station at summit of Mount Huangshan in summer 2009. Chemical characteristics, source of pollutants and microphysical properties of fog/cloud are analyzed based on the surface observational data at Guangmingding Station and the fog/cloud samples. Results show that the fog/clouds at Mount Huangshan are weakly acid, with the mean value of pH at 6.4 .The descending order of concentration of major ionic species in fog/clouds is: SO42- >NH4+>Ca2+>NO3->Na+>Cl-, indicating that secondary pollutants contributed greatly to fog/cloud. Due to the differences in contribution from regional pollutant sources and marine sources, soluble components varied greatly in different fog/cloud events. Backward trajectory analysis reveals that fog/cloud air mass is originated from marine and surrounding area. The ionic composition, microphysical properties and parameters of fog/cloud are significantly differences in various air masses.
