Aerosol samples were collected in Prague-Libus suburbs (50.008N, 14.447E, altitude 304 m) between 11-16 December 1998. 24 hours aerosol sampling was performed. The PM10 and PM2.5 fraction of atmospheric aerosol was sampled using a low-volume Harvard Impator (HI) while eight fractions of size separated aerosols were collected using the Berner low pressure impactor (BLPI) model 25/0,018/2.
Different meteorological situation is reflected in both size distribution and lead isotope ratios of aerosol sampled.
