ALGAL INHIBITION, ACUTE TOXICITY
Algal inhibition – Acute toxicity has been defined evaluating EC50 (72h) on Selenastrum Capricornutum (guideliness OECD 201:2011).
SELENASTRUM CAPRICORNUTUM TEST
The different dilutions have been placed in contact with a suspension of Selenastrum Capricornutum, and incubated for 72h.
After incubation the population density of seaweeds has been compared with a control sample to obtain EC50 (72 h).
The result of the test is EC50 (72 h) >100 mg/L.
