Description of key information
Additional information
The lowest EC50 value Acute aquatic toxicity data are available for fish (BTX) and for daphnia and alga.
The lowest EC50/LC50(48 h) value of 3.8 mg/L was found under closed conditions in the daphnia test.
This finding is in line with result for key components:
The LC50(96 h) values in fish for BTX aromatic compounds all fall within the range of 1 - 10 mg/L.
This supports classification of light oil as toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment (N, R51/53).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
