    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

    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.

    Efectos toxicológicos del consumo de lectina de frijoles en la población de la ciudad de Ambato
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos y Biotecnología. Carrera de Ingeniería en Alimentos, 2021-01) Cynthia Stephanie, Coca Cando; Cerda Mejía, Liliana Alexandra
    Beans provide nutrients like carbohydrates, protein, fiber, minerals, and vitamins; so, they stand out as a food of nutritional and economic importance in any country in the world. But, on the other hand, there are antinutritional and toxic compounds that can affect human health. Among these components are plant lectins, which are proteins with high specificity to recognize carbohydrates, therefore, when ingested through undercooked beans, they easily bind to the cell surfaces of the small intestine, interfere with the passage of nutrients and they even damage the intestinal wall causing bacterial proliferation. Toxicity can present with nausea, vomiting, and diarrhea. However, lectins can be deactivated by cooking them properly. For this reason, the need arises to broaden the subject through a bibliographic search and the application of a virtual survey, methodologies used due to the health emergency caused by Covid-19, which allow achieving the objectives set and finding the toxicological effects that the Lectins from beans may affect the health of the inhabitants of the city of Ambato.
