A chemical characterization of atmospheric aerosol in Sapporo
Abstract Monthly mean chemical composition of aerosol with diameter less than 8 μm was identified in Sapporo in 1982. The mass of aerosol was made up of nine components: elemental C, organics, SO42−,Expand

Seasonal variation in the chemical composition of atmospheric aerosols and gaseous species in Sapporo, Japan
Abstract Simultaneous samplings of atmospheric aerosols and gaseous precursors (SO2, HNO3,NH3) were conducted during an 18-month period in Sapporo, Japan. The monthly mean mass concentration ofExpand
