Report on subacute toxicological studies with several fluorocarbons in rats and dogs by inhalation

The 90-day inhalation studies, conducted in 1975, showed that for the fluorocarbons the lowest toxic concentrations could be regarded above 5,000 ppm by volume of air (0.5% by vol.) when administered to Beagle dogs. With rats the lowest toxic concentrations were above 10,000 ppm by volume. Administration took place on 90 consecutive days for 6 h per day.
