Additional information
Data are available for the streams 64742-90-1, 68513-69-9, 85117-10-8, 69013-21-4 and 98072-36-7 from Brixham Environmental Laboratory (2004), Exxon (2003), BASF (2007), ExxonMobil (2003, 2004) and ECT Oekotoxikologie GmbH (2012). The ErL50 values reported ranged from 2.1 to 12.2 mg/L and the NOErLR ranged from 0.18 to 8 mg/L. These studies are considered reliable for assessment and so data will be read across to other members of the category.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
