Description of key information

PFBE is a highly volatile liquid of low water solubility (15.6 mg/l). Volatilisation from the aquatic environment is expected to be an important fate process for any releases, based on the estimated Henry's law constant (3 -100 atm.m3/mol) and this compound's high vapour pressure (22 kPa at 20°C). Consequently detectable concentrations will be hard to achieve in the aquatic enviroment.
Moreover, direct and indirect exposure of the aquatic environment to PFBE is unlikely, and in accordance with Column 2 of REACH Annex IX 9.3.2, bioaccumulation testing in aquatic species is waived. (See the document PFBE: REACH Annex IX waivers for Degradation and Fate and Behaviour in the Environment. Blue Frog Scientific Limited. Attached to Section 5 Summary Environmental Fate and Pathways)
