We also investigated whether specific sources of particles from mobile sources, represented by black carbon (BC), and sulfates (SO4), a surrogate for fossil-fuel burning power plants, were differentially associated with these effects, and whether those effects were modified by SNPs in miRNA-processing genes.
In the era of leaded gasoline, mobile (vehicular) sources represented the dominant input.
Supplemental material, Figure 3 shows the decrease in the total NOx emissions from on-road mobile sources in Canada (used here to represent primary vehicle emissions), including heavy and light duty diesel and gasoline vehicles, from 1980 to 2007 and extrapolated levels to 1970.
In this study, we use longitudinal data from the Normative Aging Study NASS) to investigate whether ambient concentration of black carbon (BC), primarily representing mobile source particles, outside an individual's home during the previous year was associated with telomere length.
Taken together, our results indicate that a variety of mobile sources contribute to ambient vehicle exhaust particles in the trucking industry, with EC representing mainly diesel sources and OC representing a mixture of mobile sources that depend on the work environment.
All monitors in the continental United States were included, because excluding monitors such as those located near point or mobile sources would prevent us from incorporating all sources of spatial variability represented in the monitoring network.
Intercensal emigration and differential completeness of census enumeration associated with massive outflows of refugees in the wake of the Vietnam War, population-redistribution policies, and a highly mobile population represent important sources of bias for the estimation of intercensal mortality.
Recall from Equation 14 that we can represent a mobile source as L F = { u F,0, u F,1,.., u F, T }.
"Most of it comes from mobile sources: cars," she said.
The examples include programs involving stationary, area, and mobile sources.
