USEPA Region 9 Laboratory Mercury Monitoring Flow Diagram The Region 9 Laboratory is a full service laboratory offering a wide variety of analyses which can support the work of all the media divisions in Region 9. In the area of mercury analysis, the laboratory offers both field and fixed lab analyses in all matrices, including: water, soil, sediment, waste, biota, and air. The laboratory also maintains field sample collection capability for all the matrices analyzed. Atmospheric Mercury Vapor Monitoring Tlie Region 9 Laboratory monitors atmospheric mercury in the elemental, particulate and reactive phases. Utilizing a mobile trailer platform, the laboratory can provide continuous monitoring at locations throughout the Region. The mobile analytical capability includes: elemental gaseous mercury, reactive gaseous mercury, particulate mercury, ozone, NOx,' CO, and a complete meteorological station.
