“…The evidence available, covering a number of sub-Saharan African countries, generally shows significant associations between artisanal gold mining and pollution of environmental media and biota (see Nweke and Sanders, 2009;Shandro et al, 2009;Bose-O'Reilly et al, 2010b;Spiegel and Veiga, 2010). However, only few studies have investigated the independent effects of compositional, contextual, and occupational factors on knowledge of artisanal goldminers regarding mercury use, and these studies have reported mixed results (see Charles et al, 2013).…”

“…Millions of people in developing countries are involved with artisanal gold mining, accounting for approximately 20-30% of the world supply at 500-800 tons/year (Telmer and Veiga, 2009;Spiegel and Veiga, 2010). Artisanal and small-scale gold mining (ASM) is a poverty-driven activity that provides an important source of livelihood for many rural communities (Hilson, 2013;Hilson et al, 2014;Armah et al, 2016).…”

without any previous occupational health problems (OR = 4.86, p < 0.0001). Although artisanal gold miners who are 25-34 years old were more likely to know than their counterparts who are 18-24 years old, there were no differences in knowledge between those who are 35 years or older and their counterparts who are 18-24 years old. These results emphasize the complex relationships between compositional, contextual and occupational factors on the one hand, and artisanal gold miners' knowledge of environmental and health effects of Hg, on the other hand. Some policy implications of the findings suggest that a more systematic approach to the development and evaluation of interventions to phase out Hg use in artisanal gold mining is desirable, with clearer recognition of the interrelationships between compositional factors of artisanal gold miners and their persistent reliance on Hg in the gold extraction process.

“…Therefore, in the leaching process, the mercury in the waste will be carried with the water into water bodies. Estimated globally every year more than 300 tons of mercury evaporates into the air, 700 tons of polluting rivers, lakes and soil, and 100-150 tons of them occurred in Indonesia [4].…”

Artisanal gold mining waste that still contain mercury (Hg) then discharged into rivers and coastal area. Mercury in ecosystem aquatic has influence the food chain of the waterbirds. The objective of this research was to inventory the water birds species in the coastal, and describe the exposure of mercury in the organs of birds. This research conducted to the coastal region of North Gorontalo regency. Collecting data was in the Buladu and Ilangata coastal area. Data analysis to concentration mercury in the body of the water birds using Atomic Absorption Spectrophotometer (AAS) on samples of the kidneys, liver and muscle chest tissue. This study find out four species of waterbirds in the coastal area, also mercury concentrations exposure in the organs of each species, namely: (1) Butorides striatus, exposure of mercury 0.22 ppm in kidneys, 0.17 ppm in liver, 12.12 ppm in muscle; (2) Tringa melanoleuca, exposure of mercury 0.43 ppm in kidney, 0.31 ppm in liver, 0.31 ppm in muscle; (3) Actitis hypoleucos, exposure of mercury 0.19 ppm in kidney, 0.18 ppm in liver, 0.10 ppm in muscle; (4) Pluvialis squatarola, exposure of mercury 0.11 ppm in kidney, 0.10 ppm in liver, 0.10 ppm in the muscle. This research indicated that there was mercury pollution in the river, also mercury in food chain of birds living. The research strengthening the scientific knowledge in addressing to threats the bird's biodiversity, also would be use for natural resources development and policy, as well community empowerment.

“…El mercurio (Hg), la contaminación ambiental está creciendo a nivel mundial [7,8]. El Hg puede estar presente de forma natural en los suelos o como el resultado de la actividad humana, como la minería de oro [9,10].…”

“…A pequeña escala o artesanal la minería de oro con frecuencia usa tecnologías rudimentarias que involucran la amalgamación con Hg en los procesos de extracción. Aunque en el mundo existen otras técnicas de explotación, este método de extracción el cual data del tiempo de Nero (54-68 A.C), es ampliamente utilizado porque requiere de una pequeña inversión inicial y mínimo conocimiento de la tecnología [8,9]. El proceso de amalgamación es ineficiente para la extracción del oro e inevitablemente introduce Hg al ambiente (aire, agua y suelo).…”

<p>Dentro de las actividades que alteran la composición del suelo está la minería, que causa el aumento de daños visibles al suelo mediante la creación de minas a cielo abierto, escombreras, estanques de residuos y otras instalaciones de minas. El objetivo principal de este trabajo fue evaluar el efecto de la lombriz roja californiana sobre el crecimiento de microorganismos en suelos contaminados con mercurio en el municipio de Segovia, Antioquia. Estos suelos representan una problemática importante debido a la acumulación de mercurio en exceso que ocasiona la pérdida de la calidad del suelo. Para este estudio se tomaron cuatro tratamientos en diferentes concentraciones de mercurio y un tratamiento más como blanco con lombrices rojas californianas <em>(Eisenia foetida). </em>Para esto, se evaluó el crecimiento de microorganismos a través de diferentes cultivos en el laboratorio, encontrando un crecimiento satisfactorio de los mismos luego de 25 y 90 días de tratamiento. De acuerdo al comportamiento observado, se evidencia una inmovilización del mercurio y una adaptación de los microorganismos al suelo contaminado, mostrando un aumento significativo de estos con el transcurso del tiempo.</p>
