Source Apportionment of Diesel Particulate Matter in the Southeastern United States Using Models3/CMAQ
Source apportionment of fine particulate matter is important to identify the sources that are responsible for the ambient concentrations observed in a particular area. The fine and ultra fine sizes of diesel particulate matter (DPM) are of greatest health concern, which significantly contributes to the overall cancer risk from air toxics. The composition of these fine and ultra fine particles i...

متن کاملSource apportionment of PM2.5 in the Southeastern United States using solvent-extractable organic compounds as tracers.
A chemical mass balance (CMB) receptor model using particle-phase organic compounds as tracers is applied to apportion the primary source contributions to fine particulate matter and fine particulate organic carbon concentrations in the southeastern United States to determine the seasonal variability of these concentrations. Source contributions to particles with aerodynamic diameter < or =2.5 ...
متن کاملSource Apportionment of Total Suspended Particulate Matter in Coarse and Fine Size Ranges Over Delhi
Source apportionment of total suspended particulate matter (TSPM) and associated heavy metals has been carried out for the city of Delhi using the Chemical Mass Balance Model, Version 8 (CMB8), as well as principle component analysis (PCA) of SPSS (Varimax Rotated Factor Matrix method) in coarseand fine-size mode. Urban particles were collected using a five-stage impactor at six sites in the wi...

The nephelometer RH sensors were calibrated by placing the sensors in a sealed container above aqueous saturated salt solutions at known temperatures for an accurate prediction of equilibrium RH (Greenspan, 1977). More than 3hrs were allowed for each salt solution to reach water vapor saturation. Partic...
