Evaluación de biomarcadores en trabajadores mineros relacionados con arsénico urinario. Sector Pache, Cantón Portovelo.

Abstract

Anthropogenic activities produce a variety of toxic wastes that are released into the environment, and the main exposure occurs in arsenic metallurgy, which can cause occupational arsenicism in the worker with multiple damage to the organism and risk of contamination in rivers, plants and soils.In Portovelo in the Pache sector are the main mining sectors, where there is high concentrations of arsenic, cyanide and mercury. In the present investigation, the presence of urinary arsenic in mining workers was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) to estimate possible health risks, a sample of 30 mining workers was selected at five profit plants in compliance with the inclusion and exclusion criteria. The results were obtained using statistical models, determining that workers presented high concentrations of urinary arsenic higher than the Biological Exposure Index (0.035 mg/l), in a percentage of 27% with an average of 0.23 mg/l, and a maximum value of 0.4 mg/l and 73% were found below this index. In relation to water consumption and high arsenic values, a significant correlation was found with an R of 0.34 and a p of 0.000041.In the evaluation of transaminases (TGO-TGP) urea and creatinine normal values were found and there is no significant difference with arsenic relationship. The study of biomarkers is a tool that helps analyze early effects in exposed populations in order to prevent diseases related to arsenic intake.
