MONITORING OF PM2.5 PARTICLE FRACTION IN ZAGREB AIR

Investigations of PM2.5 in Zagreb ambient air started in autumn of 1998 by developing and testing sampling equipment and analytical procedures. For a period of five years samples were collected at only one sampling site. Parallel measurements of total suspended particulates (TSP), PM10 and PM2.5, as well as heavy metal and anion content in particle fractions were performed. Later step was the investigation of seasonal and space differences in PM2.5 particle fraction performed at four sampling sites, for a month period in summer and again in winter period. The results of these investigations, together with the conclusions of several recent WHO meetings resulted in PM2.5 Zagreb network implementation in year 2005.
