    The present research was conducted to evaluate the concentration of lead and cadmium in Apium graveolens (celery) and Allium ampeloprasum L. var. porrum (leek) sold at the Central Santa Anita market during the period August 2014 to February 2015. The concentration of heavy metals was determined using the Atomic Absorption Spectrophotometry method. In celery samples, lead levels averaged 0.20 ppm, with a minimum of 0.13 ppm and a maximum of 0.33 ppm, while cadmium levels averaged 0.23 ppm, with a minimum of 0.15 ppm and a maximum of 0.59 ppm. In leek samples, lead levels averaged 0.10 ppm, with a minimum of 0.05 ppm and a maximum of 0.18 ppm, whereas cadmium levels averaged 0.38 ppm, with a minimum of 0.18 ppm and a maximum of 0.59 ppm. The results indicate that both Apium graveolens (celery) and Allium ampeloprasum L. var. porrum (leek) exceeded the maximum limits established by the Codex Alimentarius for lead and cadmium. Therefore, it can be concluded that these vegetables contain high levels of heavy metals, representing a potential health risk for consumers.
