Description of key information
The acute toxicity of Sulfonic acids, C14-16 (even numbered)-alkane hydroxy and C14-16 (even numbered -alkene, sodium salts to sediment organsisms is low.
Key value for chemical safety assessment
- EC50 or LC50 for marine water sediment:
- 767.47 mg/kg sediment dw
Additional information
One sediment study according to OSPAR, 1995, Protocols on Methods for the Testing of Chemicals Used in the Offshore Oil Industry, Part A: “A Sediment Bioassay Using an Amphipode Corophium” is available. The reported EC50 is 2025 mg/kg sediment dw for 37.9% substance. The EC50 for 100% substance is 767.47 mg/kg sediment dw. It can be concluded that toxic effects on sediment organisms might only be expected at high concentrations. The test substance exhibits only a low toxicity, and due to the readily biodegradability and the low adsorption potential to sediment (Koc between 0.65-1.607), it is not likely that it can be found in the aquatic environment and sediment in high concentrations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
