title: [The occurrence of perchloroethylene in indoor air and food in dwellings in the vicinity of dry cleaning plants].
abstract: In this presentation the results of investigations concerning the concentration of Tetrachloroethylene in indoor-air and in food in residential quarters in the vicinity of dry cleaners are reported. It could be demonstrated that a significant enrichment of Tetrachloroethylene becomes evident in fat containing food, increasing with the time of storage. Particularly in butter the limit of concentration admissible for the consumption of food was exceeded in four out of five apartments after seven days. The examination of the concentration of Tetrachloroethylene over the course of the day indicates that in dependence of the hours of operation significant differences were measurable in the concentration of Tetrachloroethylene in the indoor-air of an apartment examined, without indoor rooms building up accumulation of Tetrachloroethylene. The investigations confirm that residents in the neighbourhood of dry cleaners are exposed to high load of Tetrachloroethylene by indoor-air and food.
