Occupational lead contamination in Peru is a serious problem that has not been adequately regulated in Peru to date. The main activities that generate occupational contamination of this metal include processes such as battery manufacturing, lead scrap smelting, fire testing to quantify gold and silver in mining, etc. The Objective of this article is to identify the details that should be considered in the Lead contamination in fire assay laboratories in the analytical determination of gold and silver, and analyze their deficiencies. Data on lead contamination in fire test laboratories in Peru are difficult to find in the literature available.

Se verifica que la mayor contaminación de plomo es en el área de ensayos al fuego, y en el área de preparación de muestras debido a la condición subestándar de trabajo del material usado en el trabajo. Área de ensayos al fuego: uso de litargirio (100-250g) y área de preparación de muestras: minerales y concentrados de plomo, concentrados de minerales y en grado menor el área de análisis de minerales. Debido a la condición subestándar del procedimiento de trabajo de altas temperaturas en fundición y copelación se emite mayor vapor de plomo. Las áreas colindantes tienen menor exposición y su contenido depende de la cercanía a las áreas anteriormente mencionadas y a posibles fugas de los ductos de extracción y limpieza del lugar. Se verifica que al realizar la fundición y copelación se obtienen concentraciones muy altas de emisión de plomo. Se verifica que en muchos c...
