Any other information on results incl. tables
48-hr EL50 = 210 mg/l
95% confidence interval of 160 - 270 mg/l based on nominal loading rates. Numbers of immobilized daphnids after 48 hrs were 0, 0, 0, 0, 5, 11, 15, and 20 in the 0, 10, 22, 46, 100, 220, 460, and 1000 mg/l treatments. No excursions from protocol were noted. Analytical method used was gas chromatography-mass spectrometry. Mean reduction in the concentration of dissolved hydrocarbons during the test was 5.5% (range 0 - 23%).
Applicant's summary and conclusion
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.
