PM10 and size-resolved (9-stage) aerosol samples in the urban air of Xi’an,China were collected during the spring of 2009 including a massive dust storm occurring on April 24th and measured for inorganic ions,water-soluble organic (WSOC) and inorganic carbon (WSIC),water-soluble organic nitrogen (WSON),EC and OC.Characteristics of chemical compositions and size-distributions of those measured species in the urban samples were investigated and further compared with those simultaneously observed on the mountaintop of Mt.
