Some figures of merit are presented in Table 1. We can see a good linear correlation between pesticide concentrations analyzed and the analytical response (area) by the determination coefficients of built analytical curves, which varied between 0.9600 (methyl parathion) and
0.9994 (dursban). Furthermore, detection limits of the pesticides varied from 0.1 to 4.62 μg L−1 and limits of quantification were between 1.92 and 18.6 μg L−1.
