The ozone emission from 69 different photocopying machines was determined by a described standard procedure. The emission rates were in the range of 0 to 1350 ..mu..g/min. The concentration in the breathing zone of 19 operators was found to be between less than or equal to 0.001 and 0.15 ppm. Technical conditions for the amount of ozone generated by photocopiers are described, as well as conditions for the rate of decomposition of ozone. The efficiencies of three different types of ozone filters were tested: activated carbon granulate; polyester; and polyurethane impregnated with activated carbon. Other pollutants levels from the copying process (selenium and cadmium) were less than the limit of detection. Dust concentrations (toner) in the air exhausted from photocopies were found in the same magnitude as normal dust concentrations in offices. Vapors from the resin in the toner were often present in concentrations and gave operators an unpleasant feeling.
