The objective of the research conducted by the Center for Air Toxic Metals (CATM) is to address air toxic trace element emissions, which have become a matter of worldwide concern as well as a regulatory issue in the United States. The goal of CATM is to develop key information on air toxic metal compounds to support development and implementation of pollution prevention and control strategies that will reduce air toxic metal emissions and releases to the environment.
At the time this project was initiated, very little information existed concerning how mercury emissions varied over time and whether continuous mercury monitors, given their state of development, could be used long term to assess variability. To answer this question and to evaluate how mercury semicontinuous emission monitors operated in the field for prolonged periods of time, longer-term monitoring (25-30 days) of mercury emissions and data evaluation was completed at four different power plants. The results indicate that mercury emissions can be quite variable over a 1-month period.
