Halogenated hydrocarbons are chemical compounds containing carbon and hydrogen atoms and one or more halogens (bromine, chlorine, fluorine, iodine) in their chemical structure to form organobromine, organochlorine, organofluorine, and organoiodine compounds. The organochlorine compounds (i.e., chlorinated hydrocarbons) are a particularly well-known and hazardous group of halogenated hydrocarbons in estuarine and marine environments. As a group, the halogenated hydrocarbons consist of some of the most persistent, ubiquitous, and toxic environmental pollutants. They commonly originate from agricultural activities, industrial operations, and urbanization (Kennish, 1997; Kennish, 2001; Kennish et al., 2008).
