Sentence examples for background pollution from inspiring English sources

We also present "two-pollutant models" with both PM2.5 and highway proximity included in the model, assuming that the two markers may capture different (interrelated) aspects of ambient air pollution, namely urban background pollution (mostly due to secondary pollutants) and the near-source traffic-related pollutants with higher concentrations of primary pollutants.

The results indicate that the SSB cannot be assigned as the main source of pollutants released into the Argen River, due to a background pollution level at both investigated sites.

Such findings indicate that the health effects of traffic pollutants can be partially separated from those of background pollution levels by focusing on the intraurban spatial variability in components of PM2.5.

"This background pollution requires hemispheric scale control measures".

The concentrations of both gases decrease markedly with distance from highway to regional background pollution values.

This can also be exacerbated by the presence of strong background pollution signals from point sources during low flows.

Background: Air pollution epidemiology plays an integral role in both identifying the hazards of air pollution as well as supplying the risk coefficients that are used in quantitative risk assessments.

This is particularly important as exposure to traffic-related emissions in close proximity is characterized by a rich mixture of fine PM and gaseous pollutants that are different from the mixture of the background air pollution exposure [ 32].

We aimed to quantify relationships between tree and green space density and asthma-related hospitalisations, and explore how these varied with exposure to background air pollution concentrations.

The system currently uses ArcInfo to couple four separate submodels: a source activity/emission model (SATURN), a proprietary atmospheric dispersion model (ADMS-Urban), an empirically derived background air pollution model, and a purposely designed time activity-based exposure model (time activity-based

One-third of California's so-called background air pollution, especially in the spring, comes from East Asia/China sources.
