Additional information

In a non-GLP, 72-hour static test with the green alga Scenedesmus subspicatus according to German Industrial Standar DIN 38412 part 9, the algae toxicity was investigated. Statistical evaluation of the endpoint growth rate revealed an EC50 (72h) >0.5 mg/l, related to the nominal concentration.
