Toxicity to aquatic algae and cyanobacteria
Administrative data
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- other:
- Justification for type of information:
- This study is not applicable for strong coloured substances as the alga need light for their growth and this is difficult when the solution where the alga are inside is dark brown.This is the case with our substance. Usually for such coloured substances the Lemna growth inhibition test which is suitable for the same endpoint. Lemna are duckweed and grow on the surface of the solution. So the colour of the test solution doesn’t influence the growth of the organism.
