the evaluation of the biodegradability of methacrylic acid the following
test result is considered:
Bottle Test (OECD 301D): 86 % degradation after 28 days. (Douglas
and Bell, 1992).
the key study the criterion of the 10-day window was fulfilled.
following information is taken into account for any hazard / risk /
like all the other substances of the category, is readily biodegradable.
on the TGD the defaults for readily biodegradable substances the first
order constants and half lives for biodegradation in surface water for
all members of the category are as follows:
constant (surface water) ksw = 0.047 d-1 (at 22/25 °C)
life (surface water ) [DT50] = 14 d (at 22/25 °C)
