When this article was first published online, several errors occurred in different sections of the text. The corrections are as follows:1. In the abstract, the limit of detection (LOD) and limit of quantification (LOQ) of the analytical method were 0.2 and 0.5 μg/L for acephate and methamidophos.
2. In the methodology section concerning linearity, the samples underwent initial fortification with concentrations of 0.05, 0.5, 1, 5, 10, and 20 µg/L in 1 mL of methanol, followed by drying under nitrogen. Subsequently, the dried samples were resuspended in 100 µL for subsequent injection. Therefore, this process represented a tenfold concentration factor in the concentrations of both pesticides. The final concentrations of linearity were: 0.5, 5, 10, 50, 100 and 200 µg/L.
4. The final concentrations of LOD and LOQ were: 0.2 and 0.5 µg/L.
5. In the results, “method validation” section, the new is:
Figure 5: Analytical curve linearity with six points between 0.5 and 200 μg/L of acephate and
methamidophos in water.
6. Therefore, in the conclusion section, the concentrations of LOD and LOQ were: 0.2 and 0.5 µg/L.
