Additional information

The results from the two long term toxicity tests on Eisenia fetida with Pigments Yellow 12 and 83 conclusively show absence of toxicity to earth worms, neither in regard to reproduction, nor in regard to mortality and body weight.

As long term toxicity tests towards soil macro-organisms except arthropods (earth worm Eisenia fetida) for two different pigments of the Diarylide Yellow group had been conducted with test substance concentrations far above the solubility limit in water, from acute tests no additional information could be expected. Therefore, no acute toxicity tests were performed.

Judging from these long-term toxicity tests with two different pigments, the Diarylide Yellow Pigments are to be regarded as nontoxic to soil macroorganisms.
