long-term toxicity on aquatic invertebrates was investigated with the
waterflea Daphnia magna, in a GLP guideline study according to
OECD 211 [BMG, 2013]. Since the test item is a substance that is only
partially soluble, the test solution was
prepared as water accommodated fraction (WAF), with a loading rate of 2
mg/L. In all analytically control measurements the test concentration
was below the quantification limit of 5µg/L.
appearance of living offspring was observed between day 9 and 12 at the
loading rate of 2.0 mg/L and between day 8 and 12 in the blank control.
No effects on parental daphnids and on the offspring were determined
during the 21 days test duration. Therefore, the no observed effect
loading (NOEL) was >= 2.0 mg/L.
