Additional information

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).
