On the other hand, the insecticide carbofuran presented deterministic
ecological risk with CR values greater than 0.1 (Table 5) for all basins where this pesticide was present. Despite these high environmental pesticide values,
generating uncertainty factors as the CR criteria adopted, the probability of
associated risk was null. The frequency distribution of carbofuran in the
environment, and the dose-response curve for this insecticide for the
microcrustacean M. juniae (Fig. 3 and Table 6), did present any overlap, Fig. 3. Models for the frequency distribution of the residues and the dose-response curve for the
Mysidacea M. juniae in the presence of carbofuran, as a representation of the probabilistic risk
analysis.
