Additional information

TBHP proved not to biodegrade in OECD guideline tests of ready biodegradability. In a simulation test (OECD 303 adapted to trap CO2 and volatiles), no TBHP was detected in the effluent stream and radioactivity from 14C-labelled TBHP was related to three metabolites (TBA and 2 unknown compounds) plus dissolved CO2. The degree of mineralisation was 41.1 +/- 3.5%.
