Environmental effects

AQUATIC TOXICITY: Testing results indicate that methyl nonafluoroisobutyl ether and methyl nonafluorobutyl ether have insignificant toxicity to aquatic organisms at their saturation point (Lowest LC50, EC50, or IC50 > substance water solubility). 1,2-Trans-dichloroethylene is harmful to aquatic organisms (10 mg/L < Lowest LC50, EC50, or IC50 < 100 mg/L). These compounds are highly volatile and have high Henry's Law constants and are thus expected to move rapidly through vaporization from solution in an aquatic compartment or from a soil surface in a terrestrial compartment to the atmosphere. BIOCONCENTRATION: Methyl nonafluoroisobutylether, and methyl nonafluorobutylether are highly insoluble and very volatile. Bioconcentration is therefore unlikely and not expected as they are not likely to enter aqueous waste streams from typical uses and disposal, or, in the case of a spill, remain in the aquatic or terrestrial compartments. The high potential for these components to move from aquatic or terrestrial environments to the atmosphere indicates bioconcentration is unlikely to occur as they are not expected to be bioavailable. Thus, emphasis has been placed on the atmospheric fate. 1,2-Trans-dichloroethylene has an octanol/water partition coefficient of <3 indicating it is unlikely to bioconcentrate. ATMOSPHERIC FATE: This product has Zero Ozone Depletion Potential (ODP). Atmospheric Lifetime: approximately 6 days for 1,2-trans-dichloroethylene and approximately 4.7 yr and 3.7 yr for methyl nonafluorobutyl ether and methyl nonafluoroisobutyl ether, respectively. Global Warming Potential (GWP): 320 (100 year ITH, WMO 1998 method) for n-butyl and iso-butyl isomers and essentially zero for 1,2-trans-dichloroethylene. The mixture has a global warming potential of 160 on weight basis (100 year ITH, WMO 1998 method). Atmospheric degradation products are expected to include for methyl nonafluoroisobutyl ether predominantly isoperfluorobutyric acid, CO2, HF, and perhaps also CF3COOH; for methyl nonafluorobutyl ether: n-perfluorobutyric acid, CO2, and HF.
