Description of key information
Additional information
Acute tests on all three trophic levels were performed to examine the aquatic toxicity of the multiconstituent substance. Algae turned out to be the most sensitive species revealing an ErC50 (72h) >0.5 mg/L. Fish and daphnia were less sensitive than algae providing a LC50 (96h) >1000 mg/L and an EC50 (48h) of 55.59 mg/L, respectively. Thus, the mixture is considered acutely very toxic for aquatic organisms.
