First results of acidic and alkaline constituents determination in air particulates of Thessaloniki, Greece
Atmospheric aerosol samples were collected by a low volume sampler in a typical urban site of Thessaloniki city, from March 1989 to December 1990. The concentrations of the components Cl−, NO3−, SO42−, Na+, K+, Ca2+, Mg2+ and NH4+ were determined. Data obtained showed a significant correlation of SO42− with NH4+, Ca2+, Mg2+ and NO3−. The contribution of the sea sprays was estimated to be 47% of aerosol chlorides but only 1.5% of aerosol sulfates. Aerosol sulfates are neutralized by atmospheric ammonia to form (NH4)2SO4. Data evaluation considering wind direction led to the conclusion that local urban and industrial emission sources are primarily responsible for aerosol sulfates.
