Virtual forum on near-roadway air pollution highlights health effects

Air pollution has long been a public health concern, and the spike in pollutants often detected near roadways is receiving closer attention from researchers and policymakers. NIEHS helped broaden public understanding of these impacts in the July 10 virtual forum, “Near-Roadway Pollution and Health,” moderated by Gwen Collman, Ph.D., director of the NIEHS Division of Extramural Research and Training (DERT). “Our presenters today come from the evolving robust network of air pollution researchers supported by NIEHS,” she said.

Aviation and the Global Atmosphere: Summary for Policymakers

Library Holdings. The Intergovernmental Panel on Climate Change (IPCC) was jointly established by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) in 1988 to: (i) assess available information on the science, the impacts, and the economics of, and the options for mitigating and/or adapting to, climate change and (ii) provide, on request, scientific/technical/socio-economic advice to the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC). Since then the IPCC has produced a series of Assessment Reports, Special Reports, Technical Papers, methodologies, and other products that have become standard works of reference, widely used by policymakers, scientists, and other experts. This Special Report was prepared following a request from the International Civil Aviation Organization (ICAO) and the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer. The state of understanding of the relevant science of the atmosphere, aviation technology, and socio-economic issues associated with mitigation options is assessed and reported for both subsonic and supersonic fleets. The potential effects that aviation has had in the past and may have in the future on both stratospheric ozone depletion and global climate change are covered; environmental impacts of aviation at the local scale, however, are not addressed. The report synthesizes the findings to identify and characterize options for mitigating future impacts. Read More

Air Emission Sources

Common sources of regulated air emissions are: heating and cooling systems, degreasers, steam generators (i.e., boilers), motor vehicles, turbines, wastewater treatment works, incinerators and fuel dispensing. The Clean Air Act Section 118(a) requires that each agency and employee of the Federal government comply with all Federal, State, interstate and local requirements respecting the control and abatement of air pollution in the same manner and the same extent as any non-governmental entity. Many common sources of air pollutants at Federal facilities burn fossil fuels, resulting in emissions of carbon dioxide, a pollutant which, according to the Energy Information Administration, is still on the increase in our air.

Flexible Fuel Vehicle Fact Book

Over 100 years ago Henry Ford stirred the imagination of the world by making the first Model T to run on any combination of gasoline or alcohol. Henry Ford’s visionary concerns about urban air quality and the economic impact of high oil imports have become a reality – and so did his first dream to have cars run on renewable, clean burning, domestic ethanol. Ford, General Motors, Chrysler-Daimler and Toyota have manufactured millions of flexible fuel vehicles (FFVs) that are NOW available though their dealership networks. Learn more about their availability and technical performance. Read More
