Description of key information
Additional information
Biodegradation
The ready biodegradability was determined with a non adapted activated sludge for the test item Hostavin N20 P according to OECD 301 B / C02 evolution test.The 10 % level (beginning of biodegradation) was only reached by one replicate after a long lasting adaptation period of 20 days, the degradation came to a maximum of 35 % after 28 days. The biodegradation of the other replicate remained at a level of 1 % after 28 days.
A second test according to OECD Guideline 301 C was carried out. The biodegradation was followed by BOD and chemical substance analysis.Percentage biodegradation by BOD was 0%, 0%, 0%, average 0% and percentage biodegradation by GC was 5%, 0%, 0%, average 2%.
It can be concluded that the substance is not readily biodegradable and under the present test conditions, the test item was not biodegraded by microorganisms.
Hydrolysis
Adsorption
Bioaccumulation
A bioconcentration study according to OECD 305C and to GLP principles was carried out. The BCF was in the range of 3.2 to 23. The experimentally derived BCF values indicate that the substance has a relatively low bioaccumulation potential and does not meet the bioaccumulation criteria according to Annex XIII of the Reach regulation.
