Perceived impact on the artisanal miner's health from quinchias municipality (Colombia) by the use of cyanide and mercury in the amalgamation process of gold

Abstract

Determine the Perceived Impact on the Artisanal Miner's Health from Quinchía's Municipality (Colombia) by the Use of Cyanide and Mercury in the Amalgamation Process of Gold. Quantitative, descriptive research in a sample of 28 active miners exposed to cyanide and mercury. The process of gold amalgamation was characterized, a survey of symptom perception was carried out and laboratory tests were carried out to detect the concentration of mercury and cyanide in blood. 50% of the miners are in the trade between 21 and 30 years, with an exposure of 2.6 hours/day to mercury and cyanide. 33% of miners have levels of mercury concentration in blood between 4-4.9 micrograms per liter (μg/L), as well as refer to symptoms in the nervous and digestive systems. The results of cyanide in blood are negative. Blood mercury concentrations are associated with time in the trade, hours of exposure to mercury and perception of symptoms. The results of cyanide in blood are not coincident with the symptoms reported by the miners. Although the toxicity of these chemical substances is recognized, traditional and prohibited methods are still used without taking into account safety protocols and the use of appropriate protection elements. Miners are constantly exposed to procedures that involve health risks, refer undiagnosed symptoms and that could affect the organism in the long term. Prevention and promotion measures are not adopted.
