Key_Biodegradation in water: screening tests: The test substance showed
0% degradation after 4, 14 and 28 days of test duration and can
therefore be considered to be "not readily biodegradable" (activated
sludge, aerobic, EU Method C.4 -D)
Supporting_Biodegradation in water: screening tests_QSAR: BIOWIN v4.10
(EPIWIN software) by US-EPA (2012), overall prediction result: not
Biodegradation in water:
One experimental (key study, reliability 2)
and one QSAR prediction (supporting study, reliability 2) are available
for the substance 2,4,6 -triisopropyl-m-phenylene diisocyanate. The
experimental study was conducted according to EU Method C.4 -D (Müller,
1997). No degradation (0 %) was observed after 4, 14 and 28 days.
However, the substance was not found to be bacteriotoxic. .
In addition, a prediction for
biodegradability was performed with the computer program BIOWIN v4.10
(EPIWIN software) by US-EPA (2012). As overall prediction result the
substance is not readily biodegradable, neither under aerobic nor under
in water and sediment:
exposure to water and sediment is intended during the life cycle of the
test substance. Indirect exposure to the environment is unlikely, which
is also indicated by the manufacturing process. In accordance with
REACH, Annex IX, Section 9.2.1, column 2, this endpoint can be waived.
exposure to soil is intended during the life cycle of the test
substance. Indirect exposure to the environment is unlikely, which is
also indicated by the manufacturing process. In accordance with REACH,
Annex IX, Section 220.127.116.11, column 2, this endpoint can be waived.
