متن کاملSource 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 کاملWorkgroup Report: Workshop on Source Apportionment of Particulate Matter Health Effects—Intercomparison of Results and Implications
Although the association between exposure to ambient fine particulate matter with aerodynamic diameter < 2.5 microm (PM2.5) and human mortality is well established, the most responsible particle types/sources are not yet certain. In May 2003, the U.S. Environmental Protection Agency's Particulate Matter Centers Program sponsored the Workshop on the Source Apportionment of PM Health Effects. The...
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...
متن کاملSize-resolved source apportionment of particulate matter in urban Beijing during haze and non-haze episodes
Additional size-resolved chemical information is needed before the physicochemical characteristics and sources of airborne particles can be understood; however, this information remains unavailable in most regions of China due to lacking measurement data. In this study, we report observations of various chemical species in size-segregated particle samples that were collected over 1 year in the ...
