Description of key information

Short-term toxicity of NExBTL renewable diesel (a UVCB substance of similar composition to the substance) toward an aquatic algae Scenedesmus subspicatus was determined in a GLP compliant laboratory according to OECD Guideline 201 (Alga, Growth Inhibition Test)". There was no statistical difference (Student's t-test, p < 0.05) in the growth between the control and the WAF test group. E*L50 > 100 mg/l.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L

Additional information

NExBTL renewable diesel ia a UVCB substance of similar composition to the substance with the same major components (Figure 1).

Due to poor water solubility of the substance, the organisms were exposed to a Water Accommodated Fraction (WAF) of the test substance. This is a commonly accepted procedure for regulatory studies on poorly water soluble substances.
