Results of hydrolysis testing
(IUCLID5 section 5.1.2) show that when the substance is released into
water it is rapidly degraded within minutes and hydrolysed to the
corresponding dicarboxylic acid. A test of ready biodegradability of
4-MHHPA indicates that the substance (as the hydrolysed degradation
product) was not readily biodegradable. However, modelling of possible
biodegradation pathways indicate that aerobic degradation is likely,
intermediate degradation products being predicted which have been shown
to be readily biodegradable. In addition, direct or indirect exposure of
the aquatic and terrestrial compartments for this substance are unlikely
and simulation tests in water, sediment and soil (IUCLID5 sections 5.2.2
and 5.2.3) are therefore waived.
