*2.2.1 Analysis of results in relation to the concentration of arsenic and mercury in the fruits (mg/kg)*

Ho: There are no differences in As and Hg between sampling groups.

H1: There are differences in As and Hg between sampling groups.

In the ANOVA, it is observed that the significance values are 0.062 (As) and 0.626 (Hg), a result that is obtained when comparing the selected groups A, B, and C, respectively, according to the heavy metal of arsenic and mercury and according to the intensity of use of agrochemicals. Said value is greater than the significance of α = 0.05; therefore, the statistical decision in this regard is to accept the null hypothesis; consequently, the alternative hypothesis is rejected, concluding that here there is enough evidence to affirm that there are no significant differences in the concentration of arsenic and mercury in the fruits at different intensity of application of agrochemicals with a confidence level of 95% (see **Table 1**).

## *2.2.2 Analysis of results in relation to the concentration of lead and cadmium in fruits (mg/kg)*

In **Table 2**, it is observed from ANOVA that the significance values are 0.475 (Pb) and 0.042 (Cd), a result obtained from comparing selected groups A, B, and C, respectively, according to the heavy metals of lead and cadmium, according to the intensity of use of agrochemicals. Said value with respect to Pb is greater than the significance of α = 0.05; therefore, the statistical decision in this regard is to accept the null hypothesis; consequently, the alternative hypothesis is rejected. However, the value with respect to cadmium is less than the significance of α = 0.05; the alternative hypothesis is accepted and the null one is rejected, concluding that there is sufficient evidence that affirms the existence or not of significant differences in the concentration of lead and cadmium in fruits at different intensity of application of agrochemicals with a confidence level of 95%.

Ho: There are no differences in Pb and Cd between sampling groups.

H1: There are differences in Pb and Cd between sampling groups.
