Organochlorine compound
An organochlorine compound is an organic compound containing chlorine. Many are toxic or biologically active, and some are common pesticides, yet another is even used as a sweetener (see Splenda).
Common examples that are pesticides are Dioxin, DDT, Dicofol, Heptachlor, Chlordane, Mirex and Pentachlorophenol. One example that is not a pesticide is the class known as polychlorinated biphenyls.
