In an enhanced OECD301B study the registration substance (17 mg/L; 10.8
mg C/L) reached the required level of 60% degradation to be ultimately
biodegradable within 43 days using a non-adapted municipal activated
sludge. Continuous degradation could be observed starting at day 6
reaching a maximum of 91% degradation on day 60. The only enhancement
was the prolongation to 60 days.
In a standard OECD 301B CO2 EvolutionTest using a non-adapted municipal
activated sludg the registration substance (10 mg/L) was not readily
biodegradable, but a continuous degradation starting at day 9 could be
observed reaching a maximum degradation of 24% after 28 days.
Under the test conditions of an OECD 302B Zahn-Wellens Test the
registration substance was not inherently biodegradable.
Assessing the whole set of information the substance is not readily
biodegradable and did not reach the required pass level in a study on
inherent biodegradation, but a continuous degradation could be observed
in the two existing studies on ready biodegradability. The substance
reached the pass level of 60% degradation after 43 days and a maximum
degradation of 91% on day 60. The substance is therefore ultimately
biodegradable within 43 days.
