The California Air Resources Board (ARB) cited Dr. Wall for his leadership role in the development and implementation of all the major technology advancements ultimately leading to the near-zero levels of emissions of particulate matter and oxides of nitrogen from engines. Dr. Kirk R.

Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface. Bromine also can remove ozone from the lowest layer of the atmosphere, the troposphere. Despite ozone’s beneficial role blocking harmful radiation in the stratosphere, ground-level ozone is a harmful pollutant.

Our results will have a significant impact on our understanding of the oxidizing capacity of the atmosphere and have wide ranging implications for pollution and climate change. We have been able to quantify how fast Criegee radicals react for the first time. Carl Percival. —Welz et al. Welz et al. Oliver Welz, John D. Savee, David L.

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). The researchers included a sixth pollutant, ammonia (NH 3 ).

As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. Similar reactions influence the creation of nitrate aerosols.

The finding provides insight into how to make better catalytic converters. In some catalytic zeolites, the metal ions can break down the pollutant nitric oxide in vehicle emissions. Combined FTIR and NMR studies revealed the presence of a side-on nitrosyl species in the zeolite Cu-SSZ-13. Ja Hun Kwak, Jong H. Lee, Sarah D.

As economists and social scientists, we draw two fundamental insights from these examples of forced experimentation. Resources then move from the weaker to stronger entities, and average productivity increases. Selection involves the destruction of weaker firms so that only the more productive ones survive. military bases.

The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone. The California Air Resources Board and the US Environmental Protection Agency helped support this research. —Gentner et al. Worton, Arthur W.

Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. The scientists pointed out that converting the epoxides to aerosol is likely to be higher in polluted environments, because the aerosols’ acidity is generally higher when human activity is present.
