Concentración de cadmio y riesgo toxicológico del brócoli, zanahoria y lechuga que se cultiva en la parroquia Ricaurte del Cantón Cuenca

Abstract

Environmental pollution is one of the biggest problems that humans have to face, in this context the determination of Cadmium in crops near industrial areas is of special interest as it is considered as a probably carcinogenic toxic compound that pollutes the environment, whose The main route of entry to human beings in non-occupational exposure is food. The objective of this study was the determination of the Cadmium concentrations in 45 samples of vegetables (broccoli, carrots and lettuce) grown in the Ricaurte Parish and the determination of the toxicological risk due to their consumption; For the determination of Cadmium in the samples, the AOAC 973.34 method was used and concentrations lower than 0.05 mg/kg were obtained. The toxicological risk evaluation was carried out through four points 1) Identification of the danger; This was developed through bibliographic reviews to learn about the toxic effects of metal. 2) Exposure assessment; here the Exposure Dose (DE) was calculated. 3) Dose response curve; Where the reference dose of Cadmium (DRf) was sought, which served to calculate the hazard quotient (HQ) and Margin of Exposure (ME) and 4) Risk Characterization; The individual (IR) and population (PR) risk were calculated. This evaluation was carried out for men and women, the results of the ED in both cases was lower than the DRf, for HQ <1, for ME> 1, IR <1x10-6 and PR <1; It was concluded that there is no toxicological risk in the population of Ricaurte exposed to the consumption of other vegetables.
