There is no data on
1,4-bis[1-(tert-butylperoxy)-1-methylethyl]benzene. A read across
approach is proposed with 1,3 (or
ready biodegradability of
1,3-bis[1-(tert-butylperoxy)-1-methylethyl]benzene was evaluated in a
study performed in accordance with OECD testing guideline 301 D and GLP
requirements (due to structural analogy, read-across from supporting
substance is considered as valid, thus, results given here may apply to
[1,3(or 1,4)- Phenylenebis(1-methylethylidene)] bis[tert-butyl]
peroxide). As no biodegradation was observed at day 28, the peroxide should
not be classified as readily biodegradable.
Based upon the
adsorption potential of the substance of interest, sediment and water
compartment exposition is likely. A study
was thus conducted to determine the biodegradation of [1,3(or
1,4)-phenylenebis(1-methylethylidene)]bis[1,1-dimethylethyl] peroxide in
water/sediment simulation test, according to US EPA guideline. The
half-life in sediment/water compartment under anaerobic conditions was
determined as 29 days.
