Determinación de trazas en arsénico y plomo en muestras de orina de personas que se encuentran relacionadas con el ámbito minero en Zamora Chinchipe.

Abstract

In the present investigation we sought to determine the amount of arsenic and lead traces in people that are related to the mining field, initially individuals were selected, conducting surveys with certain parameters, then with a group of 30 people who met the parameters established; 15 people were located in zone A, 10 in zone B and 5 in zone C, each zone with different requirements. The biological sample was taken (urine), 3 collections were made each with 30-day intervals, then proceeded to the determination of traces of heavy metals by Atomic Absorption Spectrophotometry by graphite furnace for the two metals under study. With the results obtained, it was observed that the concentrations of the two metals in each zone are within the reference values established by the Institute of Health and Hygiene at Work, Spain and several authors; however, the highest values were recorded in zones A and B, due to their greater exposure to mining activity.
