The combustion of solid fuels in the home release substantial pollutants such as respirable particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), heavy metals, and many other organic pollutants [ 7] which have been linked to CVDs.
These predictions suggest that almost perfect (95% uptake) implementation of source control measures will not deliver substantial improvements in pollutant emissions.
In addition to these energy aspects, the transportation sector is responsible for a substantial part of pollutant emissions in the atmosphere, which are directly and indirectly impacting different receptors such as people, material, agriculture, climate and ecosystems [92].
In addition, empirically determined attenuation factors for single- and bipollutant models show that the potential for attenuation in the estimated effects can be quite substantial for many pollutants and exposure error types, in particular for local pollutants (with the exception of δpopulation for CO).
Besides, the domestic sewage effluents from villages nearby also contributed a substantial amount of pollutants.
Background: Residential natural gas cooking burners (NGCBs) can emit substantial quantities of pollutants, and they are typically used without venting range hoods.
Conclusions: Under a classical exposure-error framework, attenuation may be substantial for local pollutants as a result of δspatial and δtotal with true coefficients reduced by a factor typically < 0.6 (results varied for δpopulation and regional pollutants).
The microinventory completed for segment 4593 provides information that is consistent with the above, confirming the presence of few major local sources that were not accounted for in the national inventories; only one gasoline station was located in the area, and no major commercial establishments that release substantial amounts of pollutants.
During the 2008 Beijing Olympics, aggressive air pollution control measures were implemented to temporarily improve Beijing's air quality, leading to substantial reductions in air pollutant levels.
By taking advantage of this unique opportunity, we conducted a study to examine relationships between substantial changes in air pollutant concentrations and changes in levels of biomarkers reflecting inflammation, oxidative stress, hemostasis, and autonomic function in a panel of Beijing residents.
