Occupational human exposure to mercury in artisanal small-scale gold mining communities of Colombia

چکیده
• Mercury exposure (blood, urine and hair) in 238 ASGM miners was assessed Colombia. A 55% of the (n = 131) had Hg/methylmercury values hair above EPA threshold. levels amalgam burners were 6 to 8-fold higher than all other miners. Fish intake, burning manipulate significant indicators Hg exposure. Exposure clearly depend on different processing activities carried out ASGM. With aim protecting human life environment, Minamata Convention seeks reduce monitor mercury (Hg) concentrations environment. Artisanal Small-scale Gold Mining (ASGM) has been identified as most important anthropogenic source at a global scale an route Hg. In this context, study total (THg) blood, hair, methylmercury (MeHg) samples from participants with occupational relevant communities biological matrices related several variables interest such age, gender, body mass index, fish consumption, time, specific activities, amalgamation burning. The median THg blood (3.70 µg/L), (4.00 µg/L) (1.37 mg/kg), MeHg (1.47 mg/kg) for below permissible set by WHO. However, about 40% showed and/or WHO thresholds. studied, amalgams significantly who did not burn amalgams, 7-, respectively. multiple linear regression model revealed that consumption predictors Miners Guainía highest likely due high manipulation amalgam, consumption. contrast, Caldas lowest biomarkers because they do or well reporting Our also highlighted gold depends their work practices. Therefore, implementation health education programme mining strategies is required, especially Guaina, Vaupés, Córdoba, Antioquia departments.

متن کاملHuman exposure to mercury due to small scale gold mining in northern Tanzania.
In northern Tanzania large numbers of small scale miners use mercury in the gold extraction process causing contamination of the environment and risks to human health. Human exposure to Hg was assessed in populations in and around small scale gold mining camps by means of human hair and urine surveys. We also determined Hg concentration in fish in aquatic bodies close to these camps. Urinary Hg...
متن کاملGlobal Burden of Disease of Mercury Used in Artisanal Small-Scale Gold Mining.
BACKGROUND Artisanal small-scale gold mining (ASGM) is the world's largest anthropogenic source of mercury emission. Gold miners are highly exposed to metallic mercury and suffer occupational mercury intoxication. The global disease burden as a result of this exposure is largely unknown because the informal character of ASGM restricts the availability of reliable data. OBJECTIVE To estimate t...
متن کاملProbabilistic meta-analysis of risk from the exposure to Hg in artisanal gold mining communities in Colombia.
Colombia is one of the largest per capita mercury polluters in the world as a consequence of its artisanal gold mining activities. The severity of this problem in terms of potential health effects was evaluated by means of a probabilistic risk assessment carried out in the twelve departments (or provinces) in Colombia with the largest gold production. The two exposure pathways included in the r...
