Description of key information

Growth of algal cultures, as measured by growth rate, exposed to water accommodated fractions of Hydrocarbons, C8-C11, n-alkanes, isoalkanes, <2% aromatics, was not inhibited by more than 50% over 72 hours. Therefore, the 72-hr EL50 values for this endpoint is reported as >100 mg/L. The 72-hr NOELR value for growth rate is 100 mg/L.
