Additional information

Biodegradation in water: screening tests


The substance is not readily biodegradable, according to OECD criteria (Read-Across to CAS 147 -14 -8 and CAS 12239 -87 -1, see IUCLID Ch. 5.2.1)


 


Biodegradation in sediment and surface water


Data waiving according to EC 1907/2006 Annex IX. The test substance was found to be poorly biodegradable in water. Hence, it is assumed that the results of simulation studies would not reveal any different findings. Therefore, simulation studies on surface water and sediments are not provided. Furthermore, the substance is not expected to be adsorptive. Therefore, simulation studies are scientifically not justified.


 


Biodegradation in soil


The substance is not classified according to GHS and shows no hazard to aquatic organisms. Thus, the use of the substance can be considered as safe and no testing is required according to EC 1907/2006 Annex IX, column 2. Furthermore, the substance is very stable and heteroagglomeration/aggregation with other particles with same material or other particle, e.g. organic matter, or to the interface between phases is very unlikely due to the very low water solubility, low logKow value and non-occurrence of functional groups of the molecule. Aditionally, the substance is not expected to be adsorptive. Thus, simulation biodegradation tests in soil are not proposed, since no relevant new findings are expected from such investigations.
