Hazardous halogenated aliphatic hydrocarbons include mostly straight-chain hydrocarbons (alkanes containing single bonds, such as methane and ethane, and alkenes containing one double bond between carbon atoms, such as ethene and propene) in which one or more hydrogen atoms are replaced by atoms of the halogen group of elements (fluorine, chlorine, or bromine). Moore and Ramamoorthy110 reviewed the behavior of aliphatic hydrocarbons in natural waters.
Tabak and colleagues111 found most compounds in the group to be subject to significant degradation under experimental aerobic conditions. At least ten of the compounds are subject to biodegradation under anaerobic conditions. Britton112 discusses microbial degradation of aliphatic hydrocarbons in more detail.
