Psychoorganic syndrome from exposure to fluorocarbon 113--an occupational disease?

A cross-sectional clinical study of 99 workers engaged in degreasing with halogenated hydrocarbons has been carried out. Among 23 cleaners from one factory, all at the time using fluorocarbon 113, we found 3 persons with symptoms and signs of psychoorganic syndrome after heavy exposure to fluorocarbon 113 for 2 1/2-4 1/2 years. The possibility of developing psychoorganic syndrome from occupational exposure to fluorocarbon is discussed by presenting these 3 cases.
