In three new studies performed to OECD guidelines and GLP, the test
substance 3-PPB was determined to be readily biodegradable,
hydrolytically unstable under basic conditions and adsorbing to soil.
The test substance was hydrolytically stable under acidic and neutral
conditions, but unstable under basic, conditions pH9 with a half-life of
24 days at 25°C in a OECD Guideline 111 (Hydrolysis as a Function of pH)
test performed to GLP guidelines. The substance seemed to exhibit
immobility in the soil as suggested by the soil partition coefficient of
3-PPB measured as 12000 (log10 Koc value of 4.1) in a study performed to
OECD 121 guideline. However it was deemed readily biodegradable in the
"CO2 headspace test" (OECD 310).
