Abiotic degradation by hydrolysis is not
expected to take place based on the structure of the substance.
The test substance is considered to be biodegradable
but failing the 10-day window. Based on the screening criteria given in
ECHA Guidance, Chapter R.11, for PBT
and vPvB assessment, the
substance does not fulfil the P- or vP-criterion.
BCF values in the range of 560 to 1350 L/kg were measured for
2-ethylanthraquinone. During the depuration phase, the test substance
concentration in the fishes quickly decreased. The substance does not
fulfil the bioaccumulation trigger value of BCF > 2000 L/kg as given in
ECHA Guidance, Chapter R.11, and does not fulfil the B- or vB-criterion.
Transport and distribution
Based on the adsorption coefficient Koc of 4070, the substance is
considered to be slightly mobile in soil and sediment according to the
criteria set up by McCall (1981).
