R22 Air Conditioning Refrigerant Toxicological Data:

1. Acute toxicity
LC50: 35% (inhalation in rats, 15 minutes)
2. Subacute and chronic toxicity
Rabbits, rats, and mice inhaled 0.2% concentration for 6 hours per day for a total of 10 months, all of which showed no toxic reactions; 1.4% concentration, weight loss, decreased serum protein, and increased globulin. On autopsy, alveolar interstitial thickening, pulmonary edema, and degeneration of the heart, liver, kidneys, and nervous system were observed.
3. Mutagenicity
Microbial mutagenicity: Salmonella typhimurium 33% (continuous, 24 hours).
Microsomal mutagenesis: Salmonella typhimurium 33% (continuous, 24 hours)
4. Teratogenicity
Inhalation of a minimum toxic dose (TCLo) of 5ppm at 6-15 days after pregnancy in rats resulted in developmental abnormalities of the eyes and ears.
