Analysis of Ambient VOCs Levels and Potential Sources in Windsor
Chemical Mass Balance (CMB), Positive Matrix Factorization (PMF), and Principal Component Analysis (PCA) were applied to investigate the major sources of Windsor ambient Volatile Organic Compounds (VOCs). The annual average total VOC concentrations declined from 2005 to 2006. Summer concentrations …

Characterization, seasonality and source apportionment of fine particulate organic matter at urban an d rural sites
… organic species as molecular markers with the chemical mass balance (CMB) model. The unapportioned organic carbon (OC) was determined as the difference between measured OC and OC apportioned to primary sources. This unapportioned OC was then correlated with pinic and pinonic acid. The …

CMB7 receptor modelling of airborne particulate matter in the Vaal Triangle
… over one week sampling periods. Thirty three chemical species were analysed for use in the Chemical Mass Balance receptor model. Teflon filters were used for inorganic elemental analysis. Inorganic elements were determined by energy dispersive X-Ray Fluorescence (EDXRFS), inductively coupled …

The mineralogy and chemistry of pulverised fuel ash produced by three South African coal-burning power stations
The chemical and mineral compositions are presented for 63 pulverized fuel ash (PFA) and 16 input coal samples collected from Lethabo, Duvha and Matla power stations over the period 1987-1988. Bulk chemical composition was determined by X-ray fluorescence spectrometry. The mineral concentrations …

Ore Types And Fluid Regimes: Macassa Gold Mine, Kirkland Lake
… This is called Breccia ore.;Calculations of chemical mass balance indicate the principal chemical transfers in hydrothermal alteration of wall rocks adjacent to ore involved additions of CO(,2), but minor additions or subtractions of Fe(,2)O(,3), MnO, MgO and CaO, which alters Fe, Mg, Ca, …

Organic Tracer Analyses and Receptor Modeling of PM2.5 in Fairbanks, Alaska
… area for PM2.5 by the US EPA. Previous chemical mass balance (CMB) studies have shown that the majority of the Fairbanks wintertime PM2.5 is from residential wood combustion. But these CMB studies also identified a relatively high fraction (up to 20%) of sulfate of unspecified origin. …

The effectiveness of actively accumulating dust in rejuvenating soils and ecosystems in a super-humid, high weathering and leaching environment, West Coast, South Island, New Zealand
… component of terrestrial and marine biogeochemical cycles. Dust is recognised as an important rejuvenator by supplying nutrients and unweathered mineral material to ecosystems. While deposition rates have been regularly quantified for terrestrial environments in the past, the rejuvenating …
