Additional information

Aquatic PNECs were derived using the PETROTOX model. As the aquatic PNECs are greater than the water solubility of the test substance toxicity is not expected and so soil and sediment PNECs are not calculated.

Conclusion on classification

The acute ecotoxicity tests report that the EL and LL50 are above the WAF tested. This indicates that acute effects are not observed even at loading concentrations far in excess of the water solubility of the test substance. Poorly water soluble substances which do not exert acute toxicity at their limit of solubility may require a precautionary classification of R53 "May cause long term advserse effects in the aquatic environment" under the DSD and Chronic Category 4 under the CLP Regulations. However, this is not required for alkenes C20 - 24 as they are readily biodegradable.
