As a result, it cannot be concluded that the higher sensitivity of A. These findings suggest that the use of different organizational biological level bioassays appears to be a suitable tool for A. Other standardized toxicological assays using more distant taxonomic groups are also available and have been applied extensively Ribo and Kaiser Ribo J.

This method is characterized by being accurate and of short-term response, but the controversy in the use of mammals for bioassays has led to the search for and arrtemia of new alternative bioassays FAO FAO The bioassay was based on the exposure of the newly-fertilized eggs to different concentrations of cultured and filtered microalgae for 48 hours Table 1.
There were found evidences of terpenes, phenolic substances phenols and flavonoids and alkaloids, with differences between the vegetal part, collection period and solvent used.
