National Air Toxics Assessment
National-Scale Air Toxics Assessment
As part of EPA's National
Air Toxics Assessment activities, EPA conducted a national-scale
assessment of 33
air pollutants (a subset of 32 air toxics on the Clean Air
Act's list of 188 air toxics plus diesel
particulate matter (diesel PM)). The assessment includes four
steps that look at the year 1996. Note: As of May 2002, the results
posted for all four steps include revisions based on input from
scientific peer review.
- Compiling a national emissions
inventory of air toxics emissions from outdoor sources. Available
- Estimating ambient concentrations
of air toxics across the contiguous United States. Available
- Estimating population exposures
across the contiguous United States. Available here
- Characterizing potential public
health risk due to inhalation of air toxics including both cancer
and noncancer effects. Available here
The goal of the national-scale
assessment is to identify those air toxics which are of greatest
potential concern, in terms of contribution to population risk.
The results will be used to set priorities for the collection
of additional air toxics data (e.g., emissions data and ambient
Technology Transfer Network Air Toxics Website: There are many different
Federal, State, Tribal and Local Agencies performing work in the
air toxics arena. The work one State may be doing could directly
benefit another State with similar air toxics scenarios. Within
the USEPA there are many different program offices working on different
pieces of the the air toxics puzzle. We call this site a "network"
because this website is a central clearinghouse and repository for
air toxics information from all of these entities--and by sharing
information and data, reduce duplication of effort wherever possible.
and local air pollution control officials formed NACAA (formally known as STAPPA and ALAPCO)
over 30 years ago to improve their effectiveness as managers of
air quality programs. The associations serve to encourage the exchange
of information among air pollution control officials, to enhance
communication and cooperation among federal, state and local regulatory
agencies, and to promote good management of our air resources.
States for Coordinated Air Use Management: An interstate association
of air quality control divisions in the Northeast states. NESCAUM's
purpose is to exchange technical information, and to promote cooperation
and coordination of technical and policy issues regarding air quality
control among the member states.
