Additional information

In a 48 hour semi-static study, Daphnia magna concentrations of resorcinol were measured (Harlan, 2010). The 48 hour LC50in this study was = 1.00 mg/L (measured). In a 48 hour static study, Daphnia magna concentrations of resorcinol were calculated from compositions of the stock solutions (Herbes and Beauchamp, 1977).  The 48 hour LC50 in this study was = 1.28 mg/L (nominal).    The actual EC50 may be lower than the nominal EC50. A 48 hour flow through multi-test substance study was conducted in Daphnia pulicaria with resorcinol being one of the test substances (DeGraeve et al., 1980).    In this study 10 animals were added to each test tank unless due to limited animals only 5 were added.  Results indicated the 48 hour LC50was > 100 mg/L (nominal).
