“…In many cases, the gold heat separation processes is performed mostly in locations close to family or community members, resulting exposing other people to increase levels of gaseous mercury, while the most important and dangerous pathway of exposure to metallic mercury for artisanal gold miners and their families is through Hg vapor inhalation (WHO, 2009). Nakazawa et al (2016), indicated that the community of Palu city, Central Sulawesi was at serious risk from exposure to high concentrations of atmospheric Hg(0). The average day time point-sample Hg(0) concentrations in the city ranged from 2,096 to 3,299 nanogram/m 3 , as measured with a hand held mercury analyzer over 3 days in July 2011 and the average daytime Hg(0) concentration in the Poboya goldprocessing area was 12,782 nanogram/m 3 , which all concentrations were substantially higher than the World Health Organization air-quality guideline for annual average Hg exposure (1000 nanogram/m 3 ).The results indicated that 93% of the sample population overall was at risk of mercury toxicity, that could lead the damage to the central nervous system due to chronic exposure.…”

Artisanal Small-Scale Gold Mining (ASGM) obviously contributes to serious environmental and health issue for miners, nearby populations, and larger community when the use of mercury (Hg) occurs. Mercury amalgamation is used as a gold recovery technique by 10-12 million ASGM miners around the world and a predicted around 1000 tonnes of mercury are discharged into the environment every year as a result of poor mining practices. Exposure to mercury can cause serious health effects for future generation, and miners and their families are vulnarable group to expose with mercury vapor and methyl mercury contaminated food in ASGM areas, resulting in increase of levels of mercury in human specimens. Thus, investigating the the effects of mercury on the environment and people health are urgently necessary for developing a better solution to eliminate further mercury contamination to environment in West Nusa Tenggara (WNT) Province. A field survey had been conducted for this research in two main ASGM spots in WNT Province: Sekotong-Lombok island and Taliwang-Sumbawa island. As part of the study, an initial health survey and socio-economic of workers/miners was conducted. Volunteer participants at sampling locations across Sekotong-Lombok and TaliwangSumbawa (exposed; indirect exposed; non exposed groups) answered a questionnaire, and allowed the sampling of hair for subsequent analysis. The ore, tailing, plants and soil samples were also collected for investigating Hg concentration on the substances. The results found that the impact of ASGM on increasing economic activity leading to jobs, income and opportunities for social development is positive. However, there is risk of contamination in soil and plants environment through mining activity and high Hg concentration discovered in human body in a short time of ASGM activity. The environmental sustainability of mining can be better regulated within legalised areas. Environmental monitoring will define unacceptable risk and allow for advanced implementation of remedial measures before an uncontrollable disaster occurs.

“…[1] Studies from Burkina Faso, Indonesia, Colombia, Ghana, and the Brazilian Amazon document occupational exposures and suggest increased adverse health risks from these exposures. [2][3][4][5][6][7] These cohorts represent industrial mining communities, rather than individual extraction endeavors, and perhaps favor reports from developing countries where these commercial practices predominate. To date, few published cases describe patients in the United States with inhalational mercury toxicity from such exposures.…”

“…La exposición de la población al mercurio trae efectos adversos como problemas renales, cardiovasculares, efectos en el sistema reproductivo e inmunológico [6,19,20]. El uso de mercurio a pequeña escala, industrial y artesanal para la extracción de oro resulta en la volatilización de un estimado de 300 t de Hg directamente a la atmósfera anualmente, y de 700 t que son descargadas vía residuos de minería al aire, suelo, ríos y lagos [8,20] y que tiene como resultado miles de sitios contaminados [9]. Las grandes concentraciones en el suelo provocan un ambiente tóxico para los macro y microorganismos, llevando a la infertilidad, baja calidad y salud del 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>
