Association of size-resolved number concentrations of particulate matter with cardiovascular and respiratory hospital admissions and mortality in Prague, Czech Republic
TL;DR: The strongest association was found for the accumulation mode particles (NC346) and the association between the PM2.5 and daily cardiovascular hospital admissions was significant at 2-day lag and for a 4-day average.
Journal ArticleDOI
Source apportionment of aerosol particles at a European air pollution hot spot using particle number size distributions and chemical composition.

TL;DR: Positive Matrix Factorization (PMF) applications to NSD and chemical composition datasets are complementary and PAHs in PM1 were found to be associated with coal combustion factor and the levoglucosan correlates with urban background.
Journal ArticleDOI
Source Apportionment of Winter Submicron Prague Aerosols from Combined Particle Number Size Distribution and Gaseous Composition Data
TL;DR: In this paper, combined particle number size distributions and readily available gaseous concentration data were used to identify winter particle sources in the urban atmosphere of Prague, the capital of Czech Republic by applying bilinear positive matrix factorization (PMF2).
Journal ArticleDOI
Wood combustion, a dominant source of winter aerosol in residential district in proximity to a large automobile factory in Central Europe
TL;DR: In this article, an air pollution source reconnaissance study was conducted to identify sources of fine (PM 0.15-1.15) and coarse (PM 1.15 -10) particles in a residential district of Mlada Boleslav in winter 2013.
Journal ArticleDOI

TL;DR: An air quality comparison between an urban site (Radvanice) and a suburban site (Plesná) to estimate air pollution sources and determine their local and/or regional origins to achieve a reduction in air pollution levels is performed.
