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.
