Description of key information
Growth in an alga culture, as measured by biomass and growth rate, exposed to a 1000 mg/L water accommodated fraction of hydrocarbons, C11-C14, n-alkanes, isoalkanes, cyclics, <2% aromatics, was not inhibited when compared to the control after a 72-hour exposure. Therefore, the 72-hr EL50 and NOELR values for these two endpoints are reported as >1000 mg/L and 1000 mg/L, respectively. The data from this study are used as read-across data to hydrocarbons, C12-C16, isoalkanes, cyclics, <2% aromatics.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
