Identification and quantification of 16 priority Polycyclic Aromatic Hydrocarbons (PAHs) collected from 4 atmosphere particulate samples in December 2008 to January 2009 were determined by gas chromatography (GC). The source of the PAHs in atmosphere particulate was estimated by chemical mass balance model and improved source apportionment technique. Dust was the major PAHs source in Qingdao, a...

Time series studies have suggested that air pollution can negatively impact health. These studies have typically focused on the total mass of fine particulate matter air pollution or the individual chemical constituents that contribute to it, and not source-specific contributions to air pollution. Source-specific contribution estimates are useful from a regulatory standpoint by allowing regulat...

The optimum resource apportionment standpoint is studied for non-real-time users CDMA (code division multiple access) overturn link. A resource apportionment standpoint of concern includes channel coding, out strectching gain control and power allocation under the conventional receive operation. The restriction in the optimization include peak transmit power of the mobile station, total receive...

The components and quantities of atmospheric dust fallout have been reported to be the pollution indicator of large urban areas. The multiplicity and complexity of sources of atmospheric dusts in urban regions has put forward the need of source apportionment of these sources indicating their contribution to specific environmental receptor. The study presented here is focused on investigation of...
