Technical Abstract: The performance of two hydrogen sulfide and seven ambient ammonia monitoring technologies was recently verified by the U.S. EPA ETV Program¿s AMS Center. The nine technologies verified by the AMS Center could be used to enhance the scientific understanding of the environmental effects that emissions from AFOs have on hydrogen sulfide and ammonia concentrations in the atmosphere. The monitors were evaluated on a number of performance parameters, including accuracy, linearity, precision, response time, calibration and baseline drift, interference effects, comparability to a reference method, ease of use, and data completeness; verification results can be found at http://www.epa.gov/etv/verifications/verification-index.html. The performance data will assist users of monitoring technologies at AFOs, such as farm owners, researchers, permitters, and regulatory agencies, to better control hydrogen sulfide and ammonia emissions through better monitoring. Real-time monitoring data will also enable users of this type of technology to evaluate the efficacy of control technologies and management plans intended to reduce emissions at AFOs.
