Description of key information

PFBE is a highly volatile liquid of low water solubility and has only moderate affinity for soil (measured log Koc = 2.96 Koc = 903). Volatilisation from wet and dry soil surfaces 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). 
Moreover, direct and indirect exposure of the soil compartment is not likely, and in accordance with Column 2 of REACH Annex IX 9.2.1.3, soil simulation testing 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)
