<jats:title>Abstract</jats:title><jats:p>Acute toxicity data from the New Chemicals Database of the European Chemicals Bureau were compared for fish, <jats:italic>Daphnia</jats:italic>, and algae. The algal growth inhibition test was the most sensitive. Correlation between fish and <jats:italic>Daphnia</jats:italic> toxicity values was better than the correlation with algae.
