Chlorinated Hydrocarbon is an organic compound containing at least one covalently bonded atom of chlorine that is made up of the elements carbon (C) and hydrogen (H) at the combine for the ‘hydrocarbon’ part of the molecule, and chlorine atoms (Cl) substituted for hydrogen where a hydrogen atom was normally bonded to a carbon atom. The Chlorinated Hydrocarbon is a class of persistent, broad-spectrum insecticides that linger in the environment and accumulate in the food chain.
Reference Definition by Britannica.com: Chlorinated Hydrocarbons were developed beginning in the 1940s after the discovery (1939) of the insecticidal properties of DDT. Other examples of this series are BHC, lindane, Chlorobenzilate, methoxychlor, and the cyclodienes (which include aldrin, dieldrin, chlordane, heptachlor, and endrin). Some of these compounds are quite stable and have a long residual action; they are, therefore, particularly valuable where protection is required for long periods. Their toxic action is not fully understood, but they are known to disrupt the nervous system.
