Stack Sampling

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

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

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

Stack Sampling Agents of concern: n n n n n Sulfur Compounds Acid Compounds PM 10 Particle Sizing Ammonia Metals PAHs Dioxins/Furans Chromium

Stack Sampling n n To be useful stack sampling instruments must be: Rugged Easy to operate Inherently safe Able to generate reliable and useful results

Stack Sampling Dry Gas Meters n Instantaneous real-time monitoring n Collection filters n Collection traps n

Reliable and Useful Results n 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.
