Layman's explanation: PCP was introduced as wood preservative by Dow and Monsanto in 1936. It has been used as fungicide, herbicide, in paints, paper coatings and coatings for reusable food storage containers. Due to environmental and health concerns its use was restricted in 1988 by the EPA allowing its use as a wood preservative. It was ultimately banned in the following year. It is persistent in the environment and bioaccumulates. It contaminates all environmental compartments and has affected fish populations and other biota. PCP is found in human breast milk. Exposure is known to cause cancer and birth defects in laboratory animals. PCP is also known to form dioxins in the atmosphere.
