Additional information

The reference substance MonoFA_TETA_PAA_BADGE_BGE_Adduct was tested for acute toxicity to green algae ( Pseudokirchneriella subcapitata ) according to OECD 201 under GLP. The 72h-EC10 was determined being 0.057 mg/L whereas the 72h-EC50 was found being 0.147 mg/L in this study (all values based on growth rate and nominal concentrations). Thus the substance is considered very toxic to freshwater algae in this study.
