The bibliographic data dealing with the acute toxicity of two phenylcarbamates, propham and chloropropham, are not very precise an often contradictory. This work is a restatement and also a demonstration of the high sensitivity of the aquatic animals that we have tested (Amphibia and Crustacea) in comparison with the Mammals (rat and mouse).
