Table 2: Number of Introduced Daphnids and Incidence of Immobility
Nominal concentration (mg/L)
In a 48 h acute toxicity test conducted according to OECD guideline 202, Daphnia
magna were exposed to the test item at nominal concentrations of
0.1, 1.0 and 10 mg/L (duplicate, 5 daphnids per replicate) and 100 mg/L
and an untreated control (both quadruplicate, 5 daphnids per replicate).
Measured concentrations were at 102 -104% relative to nominal throughout
the test. Therefore, effect parameters were based on nominal
concentrations. No immobility was observed in the control and the two
lowest test concentrations throughout the test, while 20% effect was
observed at the highest concentration after 48 h of exposure. The
48h-EC50 for Daphnia magna exposed to the test item exceeded a
nominal concentration of 100 mg/L. The study is considered to be
reliable without restrictions.
