Testing for biodegradability in surface water according to OECD 309
classifies the substance as vP. ECHA Guidance R.11 (V 3.0, p. 53) states
that “The P/vP assessment should cover all three (five) environmental
compartments (water, marine water, sediment, marine sediment, soil).
However, a substance can already be concluded as P or vP if the criteria
are fulfilled for one compartment only. For the purpose of reducing
efforts of testing, the test should be selected in such a way that it
reflects the worst case of persistence potential.” As stated in ECHA
decision number SEV-D-2114341466-49-01/F "surface water seems to be a
compartment of concern". For this compartment the vP criterion was now
confirmed, triggered by the der constituent 2,2'-Dimethyldiphenylether
(CAS 4731-34-4) for which a DT50 of 63d was established. Thus,
additional testing of the soil compartment is rendered uneccesary.
