Toxicity to aquatic algae and cyanobacteria

Description of key information
As the substance is poorly soluble in water, most of the studies are performed using Water accomodated fractions (WAFs) and all the results are based on nominal loadings. Thus, the values indicated below as NOECs are actually NOELRs (No observed effect loading rates). No study could lead to the calculation of EL50.
Key value for chemical safety assessment
Additional information
Twelve study reports were available for this end-point, all dealing with the toxicity of the substance “Hydrocarbons, C14-C18,n-alkanes, isoalkanes, cyclics, < 2% aromatics” that covers the substance Renewable hydrocarbons, C15-C18, branched alkanes on algae growth rate. All the studies used the marine species Skeletonema costatum. None of the studies allowed calculating 48h-EL50 that was never reached. All LL50 are superior to 10000 mg/L based on WAF studies.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
