              performed using the QuEChERS
              method. The analytical methodology
              was validated for the evaluation of 14
              pesticides, by enrichment of the plant
              and  processed in  the  same  way  as
              the actual samples. The percentages
              of recovery of the pesticides ranged
              between 55.2 and 99.6%. The analysis
              of  the  samples  was  carried  out  by
              gas chromatography coupled to mass
              spectrometry. The pesticides detected
              were a-HCH (0.038mg/kg), b-HCH
              (0.011mg/kg), lindane (0.023mg/
              kg), d-HCH (0.010mg/kg), heptachlor
              (0.035mg/kg), aldrin (0.034mg/
              kg), heptachlor epoxide (0.026mg/
              kg), p,p ‘ -DDE (0.010mg/kg), dieldrin
              (0.025mg/kg). The risk to human health
              associated  with  the  intake  of  Nopal
              was also determined, considering
              the concentrations of the pesticides
