Residues of PCP in food, water, and mammalian tissues may result from the direct use of PCP as a wood preservative and pesticide or as a result of use of other chemicals that form PCP as degradation products - i.e., hexachlorobenzene and lindane. To confound matters, PCP was judged to be the source of dioxin and dibenzofuran contamination in chickens in Canada. More than 50% of all chickens sampled contained hex-achlorinated dibenzo-p-dioxins (hexa CDDs) at concentrations of 27.0ng/kg fat and higher ...
