NMHC (nonmethane hydrocarbon) All hydrocarbons except methane; sometimes used to denote ROG. NMOC (nonmethane organic compound) Organic compounds other than methane. RHC (reactive hydrocarbon)—All reactive hydrocarbons; also used to denote ROG. THC (total hydrocarbon) All hydrocarbons, sometimes used to denote VOC. OMHCE (organic material hydrocarbon equivalent) Organic compound mass minus oxygen mass.
