A Comprehensive Network

• Gaseous Criteria Pollutants 51 sites
• Acid Deposition 21 sites
• Metals TSP 7 sites, PM-10 4 sites
• PM fine 25 sites, 7 speciation
• Carbonyls 9 sites
• Toxics (VOCs) 14 sites
• Particle Identification electron microscopy

• The objectives of the TAMs network are
• Provide a consistent, high quality, long term
  database to define air quality for VOC's.
• Measure Volatile Organic Compounds (VOCs) in
  industrial areas.
• Measure VOCs in urban and suburban areas.
• Measure VOC background concentrations in a rural
  area.
• Track industry in their effort to reduce or
  control VOC emissions.
• Track changes in the air quality in relation to
  the control of motor vehicle VOC emissions.

Conclusions

• There is a need for long term ambient air
  monitoring to evaluate trends over time.
• There is a need to provide checks on dispersion
  models with actual measurements. (source/receptor
  relationships)
• There is a need for special studies involving
  ambient and indoor monitoring.
• There is a need to evaluate overall regulatory
  effectiveness of your air toxics program from an
  exposure point of view.
• There is a need to use this information to inform
  the public and to assure protection of public
  health.
