Estimating infiltration of quasi-ultrafine aerosol by the absorbance method: Air quality in schools

Estimating infiltration of quasi-ultrafine black carbon particles by an absorbance method: air quality in Pavla Stehlíková Abstract This diploma thesis focused on the estimating quasi-ultrafine particles amount in school gyms continue previous study researched air quality in schools. The size-segregated mass concentration of particulate matter was measured in three elementary school gyms in central part of Prague, on periphery of Prague and in a small settlement Černošice during twenty campaigns, from 2005 to 2009. The mass concentration of particulate matter were measured by 5-staged Sioutas impactor. For this thesis we have selected samples on filters with particle size
