Additional information
Following statement was made in the BUA Report 21:
"In studies on the toxicity of BCEE in the water flea, Daphnina magna, Le Blanc determined a LC50 (48 hrs) of 240 mg/L at a confidence interval (95%) of 170 - 330 mg/L by applying the 1975 EPA test method 660/3-75-009. The test containers were sealed in order to prevent losses of the ether assessed as easily volatile. The results were attained in a static test conducted at 22 °C. Total hardness as CaCO3 was 173 mg/L. The oxygen concentration was greater than 6.5 mg/L."
Based on the provided information in this reviewed assessment report, this information is considered sufficiently reliable for the further assessment of BCEE.
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.
