   Air Toxics of Greatest Concern in New England

• State average risk values of six air toxics: acetaldehyde, acrolein, benzene,
1,3-butadiene, carbon tetrachloride, and polycyclic organic matter (POM)
exceeded health benchmarks in every state in New England, and state average
risk values of three air toxics: arsenic compounds, chromium compounds
and naphthalene exceeded health benchmarks in at least one state in New
England. Although there is no established cancer health benchmark for
diesel exhaust, people are exposed to high concentrations of diesel
emissions so it is also an air toxic of concern.
• Mobile sources represent a significant emission category for 5 of these
air toxics: acrolein, acetaldehyde, benzene, 1,3-butadiene and diesel
particulate.
• Background sources, including natural sources, unidentified sources, and
long-range transport, account for significant emission estimates for
acetaldehyde, arsenic compounds, carbon tetrachloride, and chromium
compounds.
• Combustion sources represent a significant emissions category for five
air toxics of concern: acrolein, acetaldehyde, chromium compounds,
naphthalene, and polycyclic organic matter (POM).  This includes
emissions from electric utility boilers, industrial boilers, as well as
residential wood stoves and fireplaces.
 This 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.
      New and Continuing
    Actions to Reduce Risks

    Implementing stationary source air
    toxics standards
    Improving monitoring and
    emission inventories
    Requiring cleaner gasoline and
    tightening tail pipe standards
    Funding community and state
    comprehensive risk reduction
    projects 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 states to regulate
    wood smoke emissions from
    outdoor hydronic heaters
