摘要: Geological samples were collected from 27 representative locations in the Athabasca Oil Sands Region (AOSR) Alberta, Canada. These resuspended onto filter substrates for PM2.5 and PM10 size fractions. Samples analyzed 229 chemical species, consisting of elements, ions, carbon, organic compounds. species are normalized to gravimetric mass derive individual source profiles. Individual profiles grouped into six categories typical those used emission inventories: paved road dust, unpaved dust close distant oil sand operations, overburden soil, tailings sands, forest soils. Consistent with their geological origin, major components minerals, elemental ions. The sum five elements (i.e., Al, Si, K, Ca, Fe) oxidized forms account 25–40% 45–82% particulate matter (PM) mass, respectively. Si is most abundant element, averaging 17–18% Facility (oil operations...
