Sažetak
Airborne particulate matter is a complex mixture of solid particles and liquid droplets suspended in the air. They vary in size, chemical composition and origin. Chemical analysis of aerosol particles has gained increasing importance because of the effects of these particles on the environment. Investigations show that airborne particles and their constituents are associated to adverse health effects, reduction of visibility, acidification of precipitation and the soiling of buildings. Even though significant association between total suspended particulate matter (TSP) and adverse health effects have been reported, much higher correlation levels were found for PM10 and PM2.5 particle fractions. Lippman and Thurston reported significant association between TSP, PM10, PM2.5, sulphates and mortality, morbidity, and adverse health effect in large populations, as follows: TSP < PM10 < PM2.5 &#8804; SO42- It is evident that aerosol acidity is the crucial factor in adverse health effect of particulate matter, and that sulphates are the best routinely available surrogate metric for H+ ions.
