“…Accordingly, the results could be generalizable to that area and others with characteristics similar to those studied. Furthermore, while other studies have explored similar aspects in the country, they used descriptive methods [20,23,39,40]. Therefore, the present work is one of the first to use an analytical focus in order to identify factors associated with high mercury values in a mining population.…”

Women are primarily exposed to mercury through the consumption of fish contaminated by gold mining activities. The main systems affected are the central nervous and renal systems, although effects on the reproductive system have also been found. Objective: To explore the relationship between mercury levels in women and their possible sources of contamination. A cross-sectional study was conducted from 2013 to 2015 with women residing in 11 municipalities in La Mojana, Colombia, using non-random sampling. Standardized instruments were used to identify sociodemographic characteristics, mercury use, mining-related activities, water and fish consumption, and other factors. Blood, urine, and hair samples were taken to quantify mercury levels. A logistic regression model was used to identify factors associated with elevated mercury values in the participants’ samples. A total of 428 women were included, with an average age of 36.7 ± 16.7 years, 3.3% of whom were pregnant at the time of the survey and 8.4% of whom were exposed occupationally. High levels of mercury were present in 62.8% of the women, in any one of the three samples processed. Those exposed occupationally and environmentally had similar values (p = 0.821). Frequency of fish consumption and source of drinking water were associated with higher levels of mercury (p < 0.05).

“…Los resultados muestran, además, que tal como se ha reportado en estudios previos sobre las prácticas de minería aurífera artesanal en Colombia, en cuanto a la cobertura de seguridad social en salud, la mayoría de quienes se dedican a este oficio se encuentran afiliados al régimen subsidiado (9) y hay baja cobertura de los programas desarrollados por el Gobierno (10). Es evidente que en la minería aurífera se continúa empleando prácticas rudimentarias (11). Si bien el uso del cianuro permite recuperar mayores cantidades de oro que cuando se utiliza mercurio, ambos son peligrosos para la salud humana y para el medio ambiente; puesto que, son sustancias toxicas.…”

Objetivo Determinar el impacto percibido en la salud de los mineros artesanales del municipio de Quinchía (Colombia) por el uso de mercurio y cianuro en el proceso de amalgamiento de oro.Métodos Investigación cuantitativa, descriptiva, en una muestra de 28 mineros activos expuestos a cianuro y mercurio. Se caracterizó el proceso de amalgamiento de oro, se realizó una encuesta de percepción de síntomas y se efectuaron exámenes de laboratorio para detectar la concentración de mercurio y cianuro en la sangre.Resultados El 50% de los mineros llevan en el oficio entre 21 y 30 años, con una exposición de 2,6 horas/día al mercurio y cianuro. El 33% de los mineros presentan niveles de concentración de mercurio en la sangre entre 4 y 4,9 microgramos por litro (μg/L) y refieren síntomas en los sistemas nervioso y digestivo. Los resultados de cianuro en la sangre fueron negativos.Conclusiones Las concentraciones de mercurio en la sangre se asocian con el tiempo en el oficio, horas de exposición al mercurio y percepción de síntomas. Los resultados de cianuro en la sangre no son coincidentes con los síntomas referidos por los mineros. Pese a que, se reconoce la toxicidad de estas sustancias químicas, aún se emplean métodos tradicionales y prohibidos sin tener en cuenta los protocolos de seguridad y el uso de elementos de protección adecuados. Los mineros constantemente están expuestos a procedimientos que implican riesgos para la salud; refieren síntomas no diagnosticados y que podrían afectar el organismo a largo plazo. No se adoptan medidas de prevención y promoción.

“…This should also take into account the need to include a baseline population in order to establish a precedent for the health status of the study population, based not on assumptions but rather on scientific findings. Also worth noting is that previous studies evaluated populations with distinct environmental circumstances (i.e., climate, humidity, and temperature, among others) and social conditions [40,41]. Additionally, since most of the previous reports were descriptive studies, our study would be one of the first to use analytical approaches.…”

In Colombia, the inhabitants of the Mojana region have historically been subjected to high levels of environmental and occupational exposure to mercury; however, there are few robust data on the magnitude of this exposure and associated factors. This study aimed to describe the levels of mercury in the workers and inhabitants in this region, and to identify the main sociodemographic and occupational factors that are associated with this exposure. A cross-sectional study was conducted, in which mercury levels were determined in biological samples (blood, urine, hair) from 1119 people in the Mojana region. A questionnaire was also administered, which was adapted from the Global Mercury Assessment. Linear regression models were adjusted for the natural logarithm of mercury levels in blood, urine, and hair, using the factors that were explored as independent variables. The study reports high mercury levels in 35.0% of blood samples (95% CI 31.9–38.1%), 28.8% (95% CI 24.9–32.8%) of urine samples, and 56.3% (95% CI 53.1–59.5%) of hair samples. The reported source of water for consumption was associated with high levels of mercury (p-value < 0.05). We provide evidence of high levels of mercury exposure for the population in the Mojana region.
