Not readily biodegradable under
ready biodegradation tests.
10 days windows criteria failed.
Two ready biodegradation tests under
OECD 301F and 301D exist and conclude to “not readily biodegradable”.
Under the key Manometric
Respirometry study (OECD 301F), the pass level of > 60%
ThOD of biodegradation is reached within 28 days. The ready
biodegradation levels of the substance were 60.3% at day 28 and 64.9% at
Moreover, under the conditions of
the supporting study of the closed bottle test (OECD 301D), 15% after 28
days were reached. There are indications that the substance is
ultimately biodegradable (60% after 98 days).
Considering that 60% of ultimate
biodegradation was reached within the 28-day period of the OECD 301F
test, the substance is readily biodegradable but failing the 10 days
windows criteria. Therefore it is possible to conclude that the
substance is not persistent under relevant environmental conditions.
