    The agricultural soils of the Chancay–Huaral river basin are located in areas close to industrial centers, and these industries are characterized by emitting high concentrations of metals such as lead and cadmium. Toxicity studies on plant organisms cultivated in these soils are scarce, and it is unknown whether they may produce toxic effects. The vegetables cultivated in these soils may be exposed to deposits of toxic substances from nearby sources such as air, soil, or irrigation with contaminated water, thus constituting another point of contact for exposure in the population of the Chancay area. Accordingly, the objective of this study was to evaluate the toxicological risk in individuals who consume raw and cooked Beta vulgaris “beetroot” with possible concentrations of lead and cadmium commercialized in the Chancay market. For this purpose, beetroot samples sold in the Chancay market were collected, and the concentrations of lead and cadmium were determined by graphite furnace atomic absorption spectrophotometry. The beetroot samples presented average concentrations of lead of 4.45 µg/kg in cooked samples, while in raw samples the average was 10.32 µg/kg. With respect to cadmium, the average concentration was 2.67 µg/kg in cooked beetroot and 2.62 µg/kg in raw beetroot, all below the permissible limits. As a result of the toxicological risk assessment in individuals exposed to raw or cooked Beta vulgaris “beetroot,” a hazard index with values below 1 (HI < 1) was obtained. In conclusion, there is a low toxicological risk to health in the population of Chancay who consume raw and cooked beetroot with the presence of cadmium and lead at concentrations that do not exceed the permissible limits established by the Codex Alimentarius.
