Gas-liquid chromatographic determination of pentachlorophenol in Mason jar lids and home canned foods. 1980

D L Heikes, and K R Griffitt

A method was developed for the determination of pentachlorophenol (PCP) in the seals and enamel of Mason lids. After extraction with acidic CH2Cl2 and methylation, the resulting pentachloroanisole was determined by gas-liquid chromatography (GLC) with electron capture detection (EC). Three of the 9 brands of lids examined contained PCP. Levels were as high as 198 micrograms/lid. Recoverires from fortified samples ranged from 92 to 103%. Six fruits and vegetables were canned by home canning techniques, using lids shown to contain PCP. PCP in these foods was determined by a procedure specifying extraction with acidic CH2Cl2 and gel permeation chromatography cleanup. Extracts were methylated and determined by GLC-EC. PCP was found in all the canned foods. Levels were as high as 16 micrograms/qt. Recoveries from foods fortified with PCP ranged from 85 to 94%. The presence of PCP was confirmed by GLC-mass spectrometric determination of the derivative, pentachloroanisole.

UI	MeSH Term	Description	Entries
D010416	Pentachlorophenol	An insecticide and herbicide that has also been used as a wood preservative. Pentachlorphenol is a widespread environmental pollutant. Both chronic and acute pentachlorophenol poisoning are medical concerns. The range of its biological actions is still being actively explored, but it is clearly a potent enzyme inhibitor and has been used as such as an experimental tool.

D002733	Chlorophenols	Phenols substituted with one or more chlorine atoms in any position.	Chlorophenol,Hydroxychlorobenzenes
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
