CAS number: 77804-81-0
The derivation of a PNEC is not possible. Justification: Compounds of
the Acetolone Pigments were tested in concentrations far above their
water solubility. No effects were observed in all test systems.
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 Acetolone Pigments neither any ecotoxicity nor mammalian
toxicity had been found, a PNECoral can not be derived.
As no toxicity for any tested species of algae, aquatic invertebrates,
fish, microorganisms and soil organisms (Eisenida fetida; Brassica
napus, Avena sativa, Glycine max) could be found neither in acute nor in
chronic tests, no environmental classification is proposed.
