OTHER DATA:
HFC-125, HFC-134a: Not active in four genetic studies
HFC-143a: Not active in two genetic studies
Toxicity to reproduction: Did not show mutagenic or teratogenic effects in animal experiments
12. ECOLOGICAL INFORMATION
Aquatic Toxicity:
HFC 143a 96-hour LC50. Rainbow trout: >40mg/L
HFC 134a 48-hour EC50, Daphnia magna: 980 mg/L
96-hour LC50. Rainbow trout: >450mg/L
Degradability (BOD): R-404A is a gas at room temperature; therefore, it is unlikely to remain in water.
Octanol Water Partition Coefficient: Unknown for mixture
13. DISPOSAL CONSIDERATIONS
