Field Validation of EPA Proposed Method 108 for Measurement of Inorganic Arsenic Emissions from Stationary Sources

Abstract

The U.S. Environmental Protection Agency’s proposed Method 108 for measurement of inorganic arsenic emissions from stationary sources has been evaluated both in the laboratory and in the field. Field studies, which are the focus of this paper, Included determination of the precision of the sampling method using concurrent dual or quad sampling trains in the measurement of inorganic arsenic emissions from a copper smelter plant and a glass manufacturing plant. Results of the field tests indicate that the precision was 3.85 % at the glass plant and 15.7% at the copper smelter. Considering the sampling sites and the variability of process operations, these results Indicate an acceptable degree of precision.
