Additional information

Aquatic PNECs were derived using the equation that underlies the PETROTOX model. As the aquatic PNEC 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

All the ecotoxicity data for Alkenes C20 -24, alpha is expressed in terms of loading rate rather than exposure concentrations. This data is not suitable for comparison with the classification criteria. Poorly water soluble substances may require a precautionary classification of R53 'May cause long term adverse 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, alpha as they are readily biodegradable.
