[Contamination of foodstuff by gases from tetrachloroethene emissions from a dry cleaners].

Tetrachloroethene (perchloroethylene) and other volatile organic compounds may contaminate the surroundings of dry-cleaning units. Increased concentrations of tetrachloroethene were found in food, human hair, textiles and dust from a vacuum cleaner in a home situated above a dry-cleaning unit. The concentrations were found to be extremely high in food rich in fat. The analytical procedure for the above-mentioned samples is described.
