    The cancer risk map represents the summation of
    outdoor air inhalation risks of carcinogens. It does not
    include all pollutants or exposure estimates from other
    pathways.

    EPA also assessed public health risks for other health
    effects, such as asthma, that may result from exposure
    to these hazardous air pollutants.

    New England continues to be a region impacted by air
    toxic emissions generated by mobile sources, local area
    sources, as well as industrial and natural sources.

    The NATA modeling of ambient air concentrations
    typically estimates lower concentrations than actual
    monitoring results for many pollutants.
Air Toxics of Greatest Concern in New England

• State average risk values of five air toxics: acetaldehyde,
  benzene, carbon tetrachloride, formaldehyde and polycyclic
  organic matter (POM) exceeded health benchmarks in every
  state in New England, and state average risk values of five air
  toxics: 1, 3-butadiene, acrolein, arsenic compounds, chromium
  compounds and naphthalene exceeded health benchmarks in at
  least one state in New England.

• Mobile sources represent a significant emission category for
  acrolein, acetaldehyde, benzene, 1,3-butadiene, diesel particu-
  late, formaldehyde and naphthalene.
• Combustion sources represent a significant emission category
  for acrolein, acetaldehyde, arsenic and chromium compounds,
  naphthalene, and POM. This includes emissions from electric
  utility boilers, industrial boilers, as well as residential wood
  stoves and fireplaces.
• Background sources, including natural  sources, unidentified
  sources, and long-range transport, account for significant ambi-
  ent air concentration estimates for 1,3-butadiene, arsenic and
  chromium compounds,  benzene, and carbon tetrachloride.
• Atmospheric transformation accounts for significant ambient
  air concentration estimates for acetaldehyde, acrolein and
  formaldehyde.
  New and Continuing Actions to Reduce Risks
  • Implementing stationary source air toxics standards
  • Improving monitoring and emission inventories
  • Requiring c eaner gasoline and tightening tail pipe stan-
    dards
  • Funding community comprehensive risk reduction proj-
    ects under programs such as Community Action for a
    Renewed Environment (CARE)
  • Expanding diesel reduction initiatives
  • Promoting energy efficiency
  • Providing pollution prevention assistance to sources
  • Implementing the National Collision Repair Campaign
  • Encouraging voluntary and regulatory efforts to address
    wood smoke emissions
