According to Annex VII of REACH Regulation
(EC 1907/2006), the study does not need to be conducted if there are
mitigating factors indicating that aquatic toxicity is unlikely to
occur, for instance if the substance is highly insoluble in water.
Disperse Red 054 is poorly soluble, i.e.
94 µg/l at 20 °C, thus aquatic species are unlikely exposed to the
substance and aquatic environment is considered as not target for the
A similar behaviour is shown by Similar
Substance 01. Details on the read-across are available in section 13.
Similar Substance 01 has a solubility in
water of 10 µg/l; in the validation of the analytical method, the
solubility in 20x AAP medium for lemna is found to be significantly
lower than the limit of quantification of the analytical method, i.e. 5
µg/l. On these bases, the significance to run studies on aquatic
toxicity at concentrations below the LOQ is found to be low; moreover,
the aquatic compartment is not considered as target of Similar Substance
