The air quality trends summaries are intended to reflect actual air quality and therefore include concentrations that may have been impacted by episodic events like wildfires and dust storms.
AirCompare maps provide information for counties that monitored outdoor air quality in the last five years and tailor that information for groups more likely to be affected by different levels of pollution.
"Reducing emissions from diesel engines is one of the most important air quality challenges facing the country. Even with more stringent federal heavy-duty highway and nonroad engine standards set to take effect over the next decade, millions of diesel engines already in use will continue to emit large amounts of nitrogen oxides, particulate matter, and air toxics, which contribute to serious public health problems. Diesel retrofits can significantly reduce harmful air pollutants, improve the working environment of those operating diesel-powered equipment, and reduce smoke and odor from diesel engines. Diesel retrofit devices usually are not original equipment but are installed on a vehicle just prior to or after it has been serviced."
The Air Toxics Screening Assessment (AirToxScreen) is EPA's screening tool that provides communities with information about health risks from air toxics. AirToxScreen is part of EPA's new approach to air toxics that provides updated data and risk analyses on an annual basis, helping state, local and tribal air agencies, EPA, and the public more easily identify existing and emerging air toxics issues.
Collection of information about air pollutant emissions controls selected by the Regional Air Quality Council, the lead planning agency for the Denver Metro/North Front Range region. The web resource includes information on the emissions reduction potential, costs, and impacts of a set of control strategies for NOx and VOC emissions to address ambient ozone.
This open collection is designed to support and enhance global research initiatives focused on understanding and mitigating the health impacts of environmental exposures.
The Framework for Evaluating Damages and Impacts (FrEDI) is a peer-reviewed, open-source, reduced complexity model that draws on peer-reviewed information to rapidly project the annual impacts of climate change within the United States, through the 21st century, under any custom temperature trajectory.
This map returns an inventory of stationary sources of air pollution based on origin coordinates, radius, and pollutant
SPECIATE is the U.S. Environmental Protection Agency’s (EPA) database of organic gas and particulate matter (PM) speciation profiles of air pollution sources, which provide the chemical composition of emissions from sources as a percentage of the total weight of PM or organic gas. Organic gas profiles may represent total organic gases (TOG), volatile organic compounds (VOC) or a variation. PM speciation profiles include data for PM of various size classes, such as PM2.5, which represents the mass of particles less than
or equal to 2.5 microns in diameter. In addition to PM and organic gas profiles, SPECIATE contains other profiles such as for nitrogen oxides, mercury and semi-volatile organic compounds (SVOC).
The resource includes an online browser which allows users to view detailed information about the emissions profile in tabular form or bar and pie charts, as well as downloadable databases.
Report describing a methodology for designing and implementing assessments of interventions to improve air quality. Includes an analysis of case studies, identification of needs, and recommendations for conducting an assessment.
