Data for the short-term aquatic toxicity of 2-Hydroxycyclohepta-2,4,6-trienone (CAS 533-75-5) is available for two trophic levels (aquatic invertebrates and algae). Data for the long-term aquatic toxicity of the substance is available for aquatic algae. The most sensitive acute and chronic effect concentrations were obtained for aquatic algae, with an ErC50 (72 h) of 0.114 mg/L and an ErC10 (72 h) of 0.0708 mg/L (geometric mean measured).
