1. Stack Sampling

2. 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

3. 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

4. Stack Sampling Agents of concern: Particulate Opacity Nitrogen Oxides
Carbon Monoxide
Oxygen
Carbon Dioxide
Aldehydes
Hydrocarbons(Total & Speciated)
Volatile Organic Compounds(VOCs)

5. 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.
