EC50 (48 hour, Daphnia magna) = 26
The toxic effects of the test item on
invertebrates was evaluated in an experimental study according to the
OCED Guideline 202 (1984). Daphnia magna were exposed to test
item concentrations of 3.2, 5.6, 10, 18, 32, 56, 100, 180 and 320 mg/l
in a static test for 48 hours and were then monitored for
immobilisation, defined as no whole body movement for 10 seconds after
water agitation at 24 and 48 hours. Flasks were monitored for oxygen
concentration, pH level and test item concentration at the beginning and
end of the study period. The EC50 at 24 and 48 hours were calculated
using the PROBIT Analysis with 95 % confidence limits and the EC50, 48h
resulted equal to 26 mg/l.
Based on the read across considerations, same
results apply to the target substance
