*2.2.8 Analysis of results in relation to the content of arsenic and mercury in runoff water (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, the significance values are of 0.469 (As) and 0.624 (Hg), a result obtained from comparing selected groups A, B, and C, respectively, according to the heavy metal content of arsenic and mercury in the runoff water of fields of production from granadilla fruit (*P. ligularis*) according to intensity of use of agrochemicals. These values are greater than the significance of α = 0.05; therefore the statistical

*ANOVA of comparison between groups of copper content in the soil of the granadilla fruit crop (*Passiflora ligularis*), according to the intensity of use of agrochemicals.*


#### **Table 8.**

*ANOVA of comparison between groups of arsenic and mercury content in runoff water in the granadilla fruit (*Passiflora ligularis*) crop, according to the intensity of use of agrochemicals.*

decision in this regard is to accept the null hypothesis; consequently, the alternative hypothesis is rejected, concluding that there is sufficient evidence to affirm that there are no significant differences in the content of arsenic and mercury in the runoff water samples at different intensity of application of agrochemicals at a confidence level of 95% (see **Table 8**).
