Size-segregated urban particulate matter: mass closure, chemical composition, and primary and secondary matter content

Forty-nine components of ambient particulate matter (PM) in size-fractionated PM were investigated at an urban background site in Katowice (Silesian Agglomeration in Southern Poland) in the non-heating season of 2012. PM was analyzed for two groups of carbon compounds (organic (OC) and elemental (EC) carbon, Lab OC-EC Aerosol Analyzer), five major water-soluble ions (NH4+, Cl-, SO42-, NO3-, and...

Mass and chemical composition of size-segregated aerosols

Atmospheric Chemistry and Physics Discussions This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract To identify the relative contribution of local versus regional sources of particulate matter (PM) in the Greater Athens Area (GAA), simultaneous mass and chemical composit...

Chemical Speciation of Particulate Matter Pollution in Urban Dhaka City

Dhaka, the capital and largest city of Bangladesh, lacks a regular air pollution monitoring network to measure and assess ambient air pollution level. Several academic and research projects attempted to measure a limited number of air pollutants near roadways in the central business district. These studies revealed that ambient concentrations of lead, benzene, particulate matter, carbon monoxid...

Chemical Mass Balance Source Apportionment of Size-Fractionated Particulate Matter in Nanjing, China

In recent years, atmospheric particulate matter has become the primary air pollutant in Nanjing, China. In order to support a scientific basis for particles reduction, it is of great importance to investigate the contribution of different sources to particulate matter. In this paper, the characteristics of chemical composition of observational data for size-fractionated particulate matter at Gu...
