Integrated sampling, continuous monitoring approaches for metal HAP emissions

Cost-effective, reliable, and accurate technologies for continuous, but not necessarily real-time, measurement of metal HAP emissions from industrial stacks. Such technologies would collect an integrated sample on some sort of media (e.g., sorbent or chemically impregnated filters, etc.) over a period of hours to days which would then be subjected to an on- or off-site analysis somewhat analogous to the approach for mercury monitoring in EPA Performance Specification 12B (40 CFR 60, Appendix B). Of particular interest include laboratory demonstrations of monitoring technology performance such as relative accuracy and detection limits. Ideally, responsive technologies would demonstrate that a representative particulate and gaseous metal sample can be collected through the proposed technology's sample transport system.
