Pm2.5 Elemental Composition and Source Apportionment in a Residential Area of Wrocław, Poland
نویسندگان
چکیده
Ambient PM2.5 aerosol samples were collected from Wroclaw residential area between January and April 2009, and their elemental compositions were studied. The mean mass concentration of PM2.5 was 36±21 μg/m. Based on the variability in elemental composition of atmospheric aerosols, using principal component analysis (PCA) and multiple linear regression (MLRA), four main sources of fine particulate matter were identified: road dust (54%), combustion of liquid fuels (4%), soil /mineral material (15%); industrial emission (10%). Also in the analysis of these data, two road dust components were identified with one being associated with local wood burning and the other with road salt.

The components and quantities of atmospheric dusts fallout has been reported to be the pollution indicator of large urban areas. The multiplicity and complexity of sources of atmospheric dusts in urban regions (e.g. industrial complexes composed of a variety of industrial processes, automobiles, construction activities etc.) has put forward the need of source apportionment of these sources indi...
متن کاملSource apportionment of PM2.5 in Beijing by positive matrix factorization
Air pollution associated with atmospheric fine particulate matter (PM2.5, i.e., particles with an aerodynamic diameter of 2.5mm or less) is a serious problem in Beijing, China. To provide a better understanding of the sources contributing to PM2.5, 24-h samples were collected at 6-day intervals in January, April, July, and October in 2000 at five locations in the Beijing metropolitan area. Both...
متن کاملDistributed Lag Analyses of Daily Hospital Admissions and Source-Apportioned Fine Particle Air Pollution
BACKGROUND Past time-series studies of the health effects of fine particulate matter [aerodynamic diameter ≤ 2.5 µm (PM2.5)] have used chemically nonspecific PM2.5 mass. However, PM2.5 is known to vary in chemical composition with source, and health impacts may vary accordingly. OBJECTIVE We tested the association between source-specific daily PM2.5 mass and hospital admissions in a time-seri...

Aerosols play an important role in the atmosphere but are poorly characterized, particularly in urban areas like the Mexico City Metropolitan Area (MCMA). The chemical composition of urban particles must be known to assess their effects on the environment, and specific particulate emissions sources should be identified to establish effective pollution control standards. For these reasons, sampl...
