Based on the results of the read across
study, the 48h EC50 for Daphnia magna due to exposure to the test
substance was considered to be >100 mg a.i./L.
study was conducted to determine the short-term toxicity of the read
across substance, mono- and di- C16 -18 PSE, to aquatic invertebrates
according OECD guideline 202, in compliance with GLP. Based on
range-finding study, Daphnia magna were exposed to a test concentration
of 100 mg/L (WAF) for 48h. The WAF and the control were analytically
verified by spectrophotometric analysis of the total phosphor content at
the start of the exposure intervals (fresh media, 0 and 24h) and at the
end of the exposure intervals (old media, 24 and 48h). The recovery
rates at the end of the exposure interval were found to be within the
+/- 20% of the initially measured values; hence the test concentrations
were expressed in terms of nominal loading concentrations. A positive
control (potassium dichromate) was included in the experiment. No
immobilised animals were reported in the control group or in the test
group.Based on the results of the
read across study, the 48h EC50 (Daphnia magna) was determined to be
>100 mg a.i./L(Noack,
