英文摘要 | To investigate the impacts of relative humidity (RH) on the size distribution and evolution of water-soluble inorganic ions (WSIIs) in Chongqing, China, size-resolved aerosols were collected using nine-stage viable Andersen cascade impactors bi-weeldy from June 2012 to May 2014. The WSIls (SO42-, NO3-, NH4+, K+, Na+, Cl-, Ca2+, Mg2+ and F-) were analyzed. The SO42-, NO3- and NH4+ peaks shifted from 0.43-0.65 mu m particles at 40-60% RH to 0.65-1.1 mu m particles at 70-90% RH. For K+, Na+ and Cl- the peak concentrations were in the size range of 0.65-2.1 mu m and increased as the RH increased from 40 to 90%. However, the Ca2+, Mg2+ and F- peaks at all RH levels were mainly concentrated in the coarse mode, and their concentrations did not increase as regularly as those of SO42-, NO3- and NH4+. All of the results suggest that RH was likely an important factor in determining the size distributions of the WSIIs. SO42-, NO3- and NH4+ increased linearly in all size ranges as a function of RH (40-90%). Additionally, SO42- presented the highest rate of mass increase at 1.8 pg/m(3)/10% RH in 1.1 |
