CAS number: -
The ready biodegradability of the test item has been determined by the
Closed-bottle test according to the OECD Guideline No. 301 D, with GLP
A nominal concentration of 2.0 mg/L of test substance was introduced
into the system.
Concrete of honeycomb cells of the bee by hexane extraction was
biodegraded by 83% at day 28 under the test conditions. Over 60%
biodegradation was achieved in a period of approximately 6 days
immediately following the attainment of 10% biodegradation after 1 day
(Figure), therefore fulfilled the 14-day time window (10-day time window
for other OECD 301 tests) criterion for ready biodegradable compounds.
Sodium acetate was degraded by 85% of its theoretical oxygen demand
after 14 days : the activity of the inoculum is thus verified.
According to this test, concrete of honeycomb cells of the bee by hexane
extraction should consequently be regarded as readily biodegradable.
OECD guideline 301D, GLP, key study, validity 1:
83 % biodegradation after 28 days, within the 14-days window.
A biodegradaton study was performed to assess the biodegradation
potential of the registered substance, under GLP conditions and
according to the OECD Guideline No. 301 D, Closed-bottle test.
