Determinación y cuantificación de metales pesados en subproductos bovino, pasto, suelos y aguas en veredas del municipio de Tibú (Norte de Santander).

Abstract

The municipality of Tibú, Norte de Santander, is mainly dependent on oil production, which produces emissions in the immediate vicinity of the industry, which contributes directly to environmental pollution, with the most affected animals grazing in their surroundings and Consumers of the by-products obtained in the slaughter process of these animals, causing disruption to health, these disorders are associated with foodborne diseases (ETAs), which are a permanent threat to public health and an important cause The objective of this study was to evaluate the concentration of Cd, Cu, Pb, Mo and Zn in meat, liver, skin, kidney and blood of cattle, soils, pastures and waters used for the consumption of animals exposed in zones High degree of pollution. Random sampling was carried out in the municipality of Tibú in the Socuavó Norte, J 10, Campo Yuca and P-30 trails. The quantification of the metals was performed for the atomic absorption spectroscopy, using the flame method, the concentrations obtained from these metals in the samples under study, were processed through the statistical software XLSTAT and its study was based on the Principal Component Analysis (ACP). It was concluded that the concentrations of the metals Cd, Cu, Pb and Zn exceeded the limits allowed by the European Union regulation 488/2012 of the commission of May 12, 2014, therefore, the cattle consumed in the trails object of De This research, represent a serious danger for the population that consumes, so it suggests to measure the impact that the consumption of these by-products has had on the human health of the population of the sidewalks of the municipality of Tibú Norte de Santander.
