Resumen

The surfactants are amphipathic molecules that promote the reduction of surface tension of water. The objectives were to estimate the LC(I)50;96h; to determine the assessment risk;to assess the water quality and the intoxication signs during the tests with the surfactants Agral®, Aterbane®BR, Ag-Bem®, Energic®, Fixade® and Gotafix® for guaru (Phalloceros caudimaculatus). The animals were exposed to the surfactants and a control treatment in completely randomized design with three replicates. To characterize the assessment risk were used the data of the estimated environmental concentration and of the LC(I)50;96 hours of each surfactant, classifying them according to a coefficient of risk. A LC(I)50;96h of surfactant Agral® was 4.33 mgL-1; Aterbane®BR 5.81 mgL-1; Energic® 3.93 mgL-1; GOTAFIX® 3.40 mgL-1; Fixade® 4.06 mgL-1 and Ag-Bem® 22.19 mgL-1. The water quality was not changed by the presence of surfactants. The intoxication signs showed were: increase in opercullar beat, loss of ability to pitching, erratic swimming and spasms. Ag-Bem® can be considered as slightly toxic and anothers moderately toxic. Aterbane®BR, Agral®, Ag-Bem® and Gotafix® are considered at risk with possibility adverse effect and Energic® and Fixade® risk likely adverse effect to the guaru. The intoxication signs of guaru may be indicative of environmental contamination by these molecules.
