Biodegradation in water: screening tests


The biodegradation potential of test item was assessed in CO2 evolution test according to OECD guideline 310B and EU method 4.C. After 28 days degradation of 2,2-Dimethyl-3-lauroyloxy-propanal was 91 %. The degradtion at end of the 10-day-window was 74 %.


 


Biodegradation in water and sediment: simulation tests


The performance of simulation tests for biodegradation in water and sediment is scientifically unjustified.


Regulation (EC) No 1907/2006 (REACH), Annex IX, Sect. 9.2.1.2 and Sect. 9.2.1.4, Col. 2, states as follows:


“9.2.1.2/9.2.1.4: The study need not to be conducted:


– the substances is highly insoluble in water; or


– the substance is readily biodegradable.


and


- if the substance is readily biodegradable; or


– if direct and indirect exposure of sediment is unlikely."


In accordance with column 2 of REACH Annex IX, Simulation testing on ultimate degradation in surface water and sediment simulation testing was not conducted since the the substance has an estimated low water solubility and it is hydrolytically unstable and readily biodegradable. Due to the unstable nature of the test substance, it can be assumed that upon contact with water and organic matter, the test item undergoes rapid degradation resulting in the formation of respective degradation products.


 


Biodegradation in soil


The performance of tests for biodegradation in soil is scientifically unjustified.


Regulation (EC) No 1907/2006 (REACH), Annex IX, Sect. 9.2.1.3, Col. 2, states as follows:


“9.2.1.3: The study need not to be conducted:


- if the substance is readily biodegradable, or


- if direct and indirect exposure of soil is unlikely. ”


In accordance with column 2 of REACH Annex IX, Soil simulation testing was not conducted as the substance is readily biodegradable. Due to the hydrolytically unstable nature of the test substance, it can be assumed that upon contact with soil and organic matter, the test item undergoes rapid degradation resulting in the formation of respective degradation products.
