Continuous Emission Monitoring
Environmental EngineeringCompletely revised and updated,The foremost reference on continuous emission monitoringAir pollution control agencies are incorporating continuous emission monitoring (CEM) systems in their increasingly rigorous regulatory programs. Once primarily used to measure the performance of air control monitoring devices, today CEM systems are increasingly applied in environmental regulatory programs. More recently, they have been applied to establish emission "allowances" in the U.S. acid rain control program. These stringent regulations have led to significant developments in CEM technology and application.
