characterization of extractable organic fine particulate
Characterization of the solvent extractable organic compounds
However, the characteristics of the SEOC in the fine particles (PM2.5) are not known, especially on an annual basis. Furthermore, the organic compounds in aerosols are known to be effective in providing source apportionment information (Simoneit, 1986). All these suggest that the finer particles are of great importance and should be

Seasonal pollution characteristics of organic compounds
Organic matter is the most abundant fraction in fine particles in Beijing, occupying 30–50% of the total mass, indicating its key role in air pollution control. However, detailed chemical characterization of particulate organic matter in Beijing has never been reported.

Characterization and Source Apportionment of Water-Soluble
Water-soluble organic matter (WSOM) in fine particles (PM2.5) collected at one rural and three urban sites from the Southeastern Aerosol Research and Characterization network were characterized with a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR–ToF–AMS). These samples were also analyzed for a suite of molecular markers by Gas Chromatography–Mass Spectrometry (GC-MS) to
Chemical characterization of fine and ultrafine PM, direct
The toxicity of both the organic extractable matter (OEM2.5-0.3) and non-extractable matter (NEM2.5-0.3) of fine particles (PM2.5-0.3) was compared to that of PM2.5-0.3 in its entirety on normal

Chemical Characterization of Water-Soluble Organic Compounds
2 Current status of characterization of organic carbon species in fine particulates 2.1 Solvent extractable organic species Carbonaceous materials (organic substances and elemental carbon), could take up 20-80% of fine particulate mass (Jacobson et al., 2000). Most often chemical speciation of organic carbon (OC) is performed on a fraction that

Sample characterization of automobile and forklift diesel
A-DEPs had more than 10 times the amount of extractable organic material and less than one-sixth the amount of elemental carbon compared with SRM 2975. Aspiration of 100 micro g of either DEP sample in saline produced mild acute lung injury; however, A-DEPs induced macrophage influx and activation, whereas SRM 2975 enhanced polymorphonuclear
