Additional information

The derivation of a PNEC is not possible. Justification: Compounds of the Naphtol-AS Pigments category were tested in concentrations far above their water solubility. No effects were observed in any test system. Consequently, no LOEC, NOEC, or ECx - values can be calculated. Since these data are a prerequisite to estimate a PNEC it is not possible to derive this value.

As for the Naphtol-AS Pigments neither any ecotoxicity nor mammalian toxicity had been found, a PNECoral cannot be derived.

Conclusion on classification

As no toxicity for any tested species of algae, aquatic invertebrates, fish, microorganisms, sediment organisms (Caenorhabditis elegans, Lumbriculus variegatus) and soil organisms (Eisenia fetida; Brassica napus, Avena sativa, Glycine max) could be found neither in acute nor in chronic tests, no environmental classification is proposed.
