Presencia de metales pesados en agua de ríos y las afectaciones clínicas producidas en el ser humano

Abstract

River pollution is produced by heavy metals such as Copper, Lead, Nickel, Arsenic, Zinc, Cadmium, Chromium, Tin and Mercury as a result of natural activities from the bioaccumulation of minerals and through the activities carried out by the man in the industrial, metallurgical, mining and agricultural fields, reflecting itself as a problem worldwide due to the chronic affectations that occur when the organism is exposed for a long time to the poison. However, at present there are methods that can determine the presence of heavy metals in rivers and identify their characteristics in order to establish their degree of toxicity and adverse effects that they cause. Likewise, an attempt has been made to implement strategies to reduce the pollution of rivers by heavy metals, since water resources and fauna in general are the most affected as they are a source of waste from man-made activities. The objective of this project is aimed at the analysis of the presence of heavy metals and the clinical affectations that they produce when being in direct contact with the human being.
