From the read across with 1,3-bis[1-(tert-butylperoxy)-1-methylethyl]benzene: the substance is not considered as readily biodegradable. In the test conditions, no inhibitory effect on the micro-organisms of the inoculum was observed.
There is no data on
1,4-bis[1-(tert-butylperoxy)-1-methylethyl]benzene. A read across
approach is proposed with
The 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.
is not biodegraded in the closed bottle test, and therefore should
not be classified as readily biodegradable. This lack of
biodegradation is not due to toxicity of the test compound because the
endogenous respiration is not inhibited by
1,3-bis[1-(tert-butylperoxy)-1-methylethyl]benzene. Lack of
biodegradation does not mean that
1,3-bis[1-(tert-butylperoxy)-1-methylethyl]benzene is recalcitrant in
nature. The stringency of the test procedures could account for the
recalcitrance of 1,3-bis[1-(tert-butylperoxy)-1-methylethyl]benzene in
the closed bottle test.
