Stack Sampling

• Stack sampling data is useful for
• Assessing the health risks to the public
• Determining actual or potential effects on the
  environment
• Selecting actions to mitigate the hazards safely
  and effectively
• Ensuring compliance with air quality standards
  and permits

Stack Sampling

• Stack sampling is done to
• identify airborne concentrations that could pose
  a toxic risk to public.
• evaluate the need for and type of recovery or
  scrubber equipment
• set up work zones or areas where contaminants are
  or are not present
• ensure production efficiency

Stack Sampling

• Agents of concern
• Particulate
• Opacity
• Nitrogen Oxides
• Carbon Monoxide
• Oxygen
• Carbon Dioxide
• Aldehydes
• Hydrocarbons(Total Speciated)
• Volatile Organic Compounds(VOCs)

Stack Sampling

• Agents of concern
• Sulfur Compounds
• Acid Compounds
• PM10
• Particle Sizing
• Ammonia
• Metals
• PAHs
• Dioxins/Furans
• Chromium

6
Stack Sampling

• To be useful stack sampling instruments must be
• Rugged
• Easy to operate
• Inherently safe
• Able to generate reliable and useful results

7
Stack Sampling

• Dry Gas Meters
• Instantaneous real-time monitoring
• Collection filters
• Collection traps

8
Reliable and Useful Results

• The response time, sensitivity, selectivity,
  accuracy and precision of an instrument are
  important in evaluating the reliability and
  usefulness of the data the instrument generates.
