Description of key information
In an acute aquatic toxicity study performed in accordance with OECD guideline 202 and GLP, Daphnia magna were exposed to ALIMET at concentrations of 0 (blank), 58, 100, 180, 320, 580 or 1000 mg (active ingredient)/L (nominal) for 48 hours under semi-static conditions. The low pH (3.9) of the test solution at 320 mg (a.i.)/L has a negative influence on Daphnids mortality or mobility. Therefore the test was performed with and without pH adjustment.
The LC50 and EC50 (48 hour), without pH adjustment, were determined to be 222 (195-261) and 200 (176-232) mg (a.i.)/L, respectively.
The LC50 and EC50 (48 hour), with pH adjustment, were determined to be 293 (242-361) and 287 (237-352) mg (a.i.)/L, respectively.
