Environmental Programs are Being Expanded to Include Monitoring of Highly Reactive Volatile Organic Compounds (HRVOC’s) – to Prevent Exposure to Toxic Gases, the Formation of Ground-Level Ozone and – to Comply with EPA and State Emissions Standards.
Baseline - MOCON, Inc. offers a full line of products including the portable Model 9000H Heated Total Hydrocarbon Analyzer, 9000NMHC Methane/Non-Methane Hydrocarbon Analyzer (catalytic method), and the Model 8900 automatic on-line Gas Chromatograph which can be configured to monitor Methane/Non-Methane Hydrocarbons (direct reading method) and Benzene, Toluene, Ethylbenzene & Xylene’s (BTEX) as well as a variety of other gases.
Environmental Programs are Being Expanded to Include Monitoring of Highly Reactive Volatile Organic Compounds (HRVOC's) - to Prevent Exposure to Toxic Gases, the Formation of Ground-Level Ozone and - to Comply with EPA and State Emissions Standards.
Monitoring HRVOC’s is rapidly becoming an essential part of today’s environmental monitoring programs due to increased public awareness, government regulations and enforcement.
Government Regulation and the Growth of Environmental Programs
The Environmental Protection Agency (EPA) and State Air Quality Departments, have instituted regulations to minimize emissions of toxic gases that can be emitted by industry, automobiles and during remediation of hazardous waste sites. It has also been determined that the release of small amounts of HRVOC’s can lead to the formation of large amounts of ozone. Ozone forms when volatile organic compounds (VOC’s) and nitrogen oxides react in the presence of sunlight. While ozone in the earth’s atmosphere helps protect us from the sun’s harmful rays, ground-level ozone is potentially harmful to human health.
Current Monitoring Practices
Several methods are being used to monitor emissions sources and track the migration of any releases that may be a health hazard for neighboring communities or the environment. These methods include portable survey instruments used to monitor Fugitive Emissions in refineries and petrochemical plants (EPA Method 21), Stack Emissions for Total Hydrocarbons (EPA Method 25A), Fenceline Monitoring for Methane/Non-Methane Hydrocarbons as well as BTEX and other HRVOC’s in Ambient Air Monitoring Networks.
