Description of key information

Read-across to the assessment entities soluble zinc substances and toluic acid is applied for the assessment of zinc toluate since the ions of zinc toluate determine its fate and toxicity in the environment. Reliable data available for soluble zinc substances and toluate indicate that the moiety of ecotoloxicological concern are zinc cations. The lowest reliable 48h-EC50 values for different freshwater species at varying solution pH and hardness range from 0.169 to 0.78 mg Zn/L whereas the LC50 is conservatively set at 82 mg/L for m-toluic acid.
