Biodegradation in water: screening tests

Regarding the biodegradation of the test item the 10 % level (beginning of biodegradation) was reached after 3 days. The biodegradation reached the pass level of 60 % on day 14. The mean biodegradation came to a maximum of 97 % after 28 days.

 

The validity criteria according to the guideline are fulfilled. The abidance of the 10-day window is not to be considered because the substance is a UVCB.

 

The test item must be regarded as readily biodegradable after 28 days.

In a supporting study regarding OECD Guideline 302B the mean biodegradation came to a maximum of 88% after 28 days.Based on these results the test item be termed as ultimately biodegradable under the conditions of the OECD guideline no. 302, since more than 70 % degradation was attained after 28 days of contact time.

 

Biodegradation in water and sediment: simulation tests

 

Waiving according to "column 2" in Annex IX of REGULATION (EC) No 1907/2006 (CSA does not indicate need for further investigations). The study need not be conducted because a direct and indirect exposure of sediment is unlikely. Substance is readily biodegradable

 

Biodegradation in soil

 

Waiving according to "column 2" in Annex IX of REGULATION (EC) No 1907/2006 (CSA does not indicate need for further investigations). The study need not be conducted because a direct and indirect exposure of soil is unlikely. Substance is readily biodegradable.
