Additional information

Acute tests on all three trophic levels were performed to examine the aquatic toxicity of the substance. Algae turned out to be the most sensitive species revealing an ErC50 (72h) of 50.8 mg/L while daphnids acute testing resulted in an EC50 (48h) of >100 mg/L, respectively. Effects towards fish were found in the same range providing a LC50 (96h) of >100 mg/L. Thus, the substance is acutely harmful to aquatic organisms.
