Description of key information
The toxicity to aquatic algae and cyanobacteria was investigated using different freshwater and marine water algae species.
The most sensitive freshwater algae species was Pseudokirchneriella subcapitata with an EC50 of 6.4 mg/L and the marine water algae Microcystis aeruginosa with an EC50 greater than 117 mg/L. The algae proved to be the most sensitive species with regard to aquatic toxicity.
