Evaluación del riesgo potencial por el consumo de yuca (Manihot Esculenta Crantz) a causa de la bioacumulación de metales pesados provenientes del suelo y agua en la parroquia Dayuma

Abstract

This project was carried out with the purpose of evaluating the risks associated with the consumption of cassava (Manihot esculenta Crantz) contaminated by heavy metals present in the soil and water in Dayuma Parish. In this research, atomic absorption spectrophotometry analysis was performed to quantify the concentration of heavy metals where values 0.500 mg per Kg in arsenic, 1.17 mg per Kg cadmium and 25.00 mg per Kg lead were obtained in both soil and cassava, thus reflecting a great absorption capacity in this tuber. These concentrations exceeded the limits established by the FAO with maximum allowable concentrations for roots and tubers of 0.02 mg per Kg in arsenic and 0.1 mg per Kg in both cadmium and lead; thus reflecting a potential risk, since these toxics cause serious problems in the health of the consumer, which was evidenced by face-to-face surveys conducted on the Quechua population of the Nueva Frontera community who affirmed that oil activities are a public health problem. Through bibliographic and laboratory analysis, the serious situation in which this population is found was evidenced, for which an adequate soil remediation plan is suggested in which the cassava used for this treatment is correctly eliminated since it is not consumable.
