Additional information
Two studies are available for freshwater invertebrates; one study is a GLP compliant OECD guideline study with Daphnia magna (SafePharm Laboratories, 2003a) The 48-h EC50 value from this study is 110 mg/l and is more critical than the other study which is also an OECD guideline study, but which has minor deviations (Slovnaft VÚRUP, a.s.a, 2005c). Furthermore, a study with the marine species Americamysis bahia (tested as Mysidopsis bahia) is available, the 96-h EC50 is 37 mg/l (T.R. Wilbury Laboratories, Inc., 1994). These values are used in the assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
