The test substance 2-ethylanthraquinone is regarded to be biodegradable
but failing the 10-day window.
The study conducted by Thus and van der Laan-Straathof (1991), in
which the test substance was coated on silica gel, is considered as the
key study as this study design reflects to the limited water solubility
of the test item. Under these conditions 81% biodegradation with no
lag-phase was observed after 28 days, however failing the 10-day window
On the basis of the results of the study by Thus and van der
Laan-Straathof, the substance is considered to bebiodegradable but
failing the 10-day window.The
