It is evident from the table and the results on acute tests that the representative substance for the Category is Castor oil, which also has reliable tests for all the trophic levels for the acute and long term exposures.
Effetcs are observed for all the tests. While in the acute tests Daphnia and Fish present comparable results, in the long term tests, Fish demonstrated as the most sensitive speciesand the relevant effect oberved has been a reduction in the lenght of the juvenile fish that sets the NOELR ca. 1 mg/l (test item).
Based on the chemical nature of the substance, no specific analytical technique is available, but the non-selective TOC analysis was performed for the determination of the test concentrations. Moreover, the dissolution of the substance in the different tests (normal shaking vs WAF technique) had a small impact in the final solubilisation of the substance, expecially when compared short to long term toxicity studies.
It is also important to notice that based on acute studies, the Castor oil derivative fish toxicity is much lower than the analogue derivative vegetable and fish, with whic animal oil is more similar; as a consequence, while calculating the DNEL and the risk assessment on the Castor oil results has been chosen in a conservative approach, on the other side, classification of the substance for the enviroment is not considered for the animal derivative
