An evaluation was done of acute toxicity of the SDS (Sodium Dodecil Sulfonate) and LAS-C12 (Linear Alkylbenzene Sulfonate) using red shrimp (Farfantepenaeus paulensis) exposed to different concentration, for periods of up to 96 hours. The acute toxicity of SDS in larvae of the pink shrimp exposed to different concentrations of this substance were: 13,66 mg L–1 for 24 h of exposure; 11.89 mg L–1 for 48 h; 9.98 mg L–1 for 72 h, and 8.66 mg L–1 for 96 h. For LAS-C12 the acute toxicity in larvae of the pink shrimp exposed to different concentrations of this substance, for period of up to 96 h were 6.37 mg L–1 for 24 h of exposure; 5.32 mg L–1 for 48 h; 4.61 mg L–1 for 72 h; and 4.25 mg L–1 for 96 h.
