Description of key information

Growth of algal cultures, as measured by biomass and growth rate, exposed to water accommodated fractions of hydrocarbons, C9-C12, n-alkanes, isoalkanes,  <2% aromatics, was not inhibited by more than 50% over 72 hours. Therefore, the 72-hr EL50 values for these two endpoints are reported as >391 mg/L. The 72-hr NOELR was 391 mg/L. No toxic effects were observed at the maximum concentration tested.
