NMHC Information


Non-Methane Hydrocarbons:

What are NMHCs:

Non-Methane Volatile Organic Compounds (NMVOCs) are a large variety of chemically different compounds such as benzene, ethanol, formaldehyde, cyclohexane, and acetone. NMVOCs are essentially identical to VOCs, with the exlusion of methane. An important subset of NMVOCs are NMHCs. NMHCs are trace atmospheric components that provide a sink for hydroxyl radicals and control ozone concentration. Exmples of NMHCs are ethane, ethene, propane, propene, and isoprene. Methane is excluded in air-pollution contexts because it is not harmful.

Health Risks:

Respiratory, allergic, or immune responses are common with exposure to NMHCs. Other health effects include eye, nose, and throat irritation, headaches, loss of coordination, nausea, liver and kidney damage, and damage to the central nervous system.

Measuring NMHCs:

NMHCs are present in the gas phase at room temperature. NMHC levels in the air are measured in units of parts per million (ppm) The products we carry to measure NMHC levels can be found HERE.
