A number of variables and attributes such as combustion process conditions and practices, as well as the quality of the raw material used affect the composition of emissions released (Ohlström et al. 2005).
The approach used is at least as effective as methods based on isotopic ratios but has the added advantage of providing direct constraint on a large suite of elements, and of being independent of changes in the isotopic composition of emissions.
Such employment is likely to affect the quantity and the composition of emissions and potential biologic effects of the exhaust (Graboski and McCormick 1998).
Second, it is important to be able to estimate changes in health risks that will result from changes in the composition of emissions.
Availability of a range of biomass fuels, varying composition of emissions and biomass emission factors of the same fuel vary across Indian states and in different seasons are some of the challenges in exposure assessment.
In general, the factor profiles, which reflect the composition of emissions in each source, (Table 1; see also Supplemental Material, Tables S3 S8) were similar across sites, as previously observed for an earlier period (Lee et al. 2011).
The composition of emissions affects toxicity, as has been demonstrated by differences in the in vitro (bacterial mutagenicity) and in vivo (lung responses to instilled material) responses among seven samples of engine emissions collected from "normal-emitting" and "high-emitting" gasoline and diesel vehicles (Seagrave et al. 2002).
The color composition of each emission indicates the phases in the commodity's supply chain during which GHG emissions occur: (D) Direct emissions in Japan during production, (S) induced emissions in Japan through the supply chain, and (F) induced emissions in foreign countries' supply chains.
Surface temperatures and the composition of the emission gas were measured.
The unique composition of this emission source particle makes it particularly useful as a surrogate for ambient air PM in studies of biologic effects testing the hypothesis that metals mediate the biologic effects of air pollution particles.
