EC50 (Daphnia magna, 48h) found was >0.0265 mg/L (Conc. determined by HPLC)
A study was conducted in accordance with the OECD Guideline for Testing
of Chemicals No.202 “Daphnia sp., Acute Immobilisation Test” (2004). A
water-accommodated fraction (WAF, test conc. 100 mg/L) was used to
expose the test species to the test substance because the substance was
poorly water-soluble and difﬁcult to be dissolved stably in the test
solutions. The result given below was calculated from the time-weighted
mean of measured concentrations. The median effect concentration (EC50)
for immobilisation is mentioned as [>test concentration] because this
test was a limit test and the immobility was 0% in Conc. 1. The 48-hour
median effect concentration (EC50) found was >0.0265 mg/L (Conc.
determined by HPLC).
