“…Also, the values found were higher than other studies in similar scenarios, which may be due to different factors such as climate, time, route of exposure, working time, and safety conditions. In this regard, workers with acceptable working conditions in northern Algeria have shown moderate and high U-Hg levels (29.3 μg/g Cr and 139 μg/g Cr, respectively) (Abdennour et al, 2002); compared with our findings, they are approximately 10 times lower.…”

Mercury is a ubiquitous environmental xenobiotic; the primary sources of exposure to this metal are artisanal gold mining and the direct production of mercury. In Mexico, artisanal mercury mining continues to be an important activity in different regions of the country. Exposure to mercury vapors releases can have severe health impacts, including immunotoxic effects such as alterations in cytokine profiling. Therefore, in the present work, we evaluated the inflammatory cytokines profile in the blood serum of miners exposed to mercury. A cross-sectional observational study was performed on 27 mining workers (exposed group) and 20 control subjects (nonexposed group) from central Mexico. The mercury urine concentration (U-Hg) was determined by atomic absorption spectrometry, and IL-2, IL-6, IL-8, IL-10, and TNF-α were measured using a Multiplex Assay. The results showed that the U-Hg in the miners had a median value of 552.70 μg/g creatinine. All cytokines showed a significant increase in the miner group compared with the control group, except for TNF-α. In addition, we observed a positive correlation between U-Hg concentration and cytokine levels. In conclusion, mercury exposure correlated with cytokine levels (considered acute inflammatory marker) in miners; therefore, workers exposed to this metal show an acute systemic inflammation that could lead to alterations in other organs and systems.

“…One of the most common uses of mercury is for the extraction of gold from gold-containing ores [3]. Mercury alters the physiological and the biochemical functions of living organisms, and causes a wide range of clinical symptoms in occupationally exposed workers [4,5]. Mercury exposure is a health concern in the occupational settings like gold mining [6].…”

Background: Mercury concentration in the blood is one of mercury exposure biomarkers. This study was conducted in Abuhamed mining area in Sudan, during the period from August 2012 to November 2014.The aim of the study was to evaluate serum mercury levels and to assess lung functions in artisanal gold miners. Methods: The study included 123 subjects, of them 83 were working in the gold mining area, beside 50 healthy volunteers from Khartoum State, as control group. Serum mercury was measured by direct mercury analyzer (DMA-80). Lung function tests were done with a portable spirometer. Data were analyzed using IBM SPSS Statistics version 20. Results:The study observed significant increase in serum mercury levels in the gold miners, when compared with control group (24.9 ± 32.24µg/l) versus (1.40 ± 0.94µg/l) with P value (0.000). The mean forced expiratory volume in the first second (FEV1) in the gold miners was (3.24 ± 0.57) versus (3.40 ± 0.39) in the control group, while the mean forced vital capacity (FVC) in the mercury exposed miners was (3.7 ± 0.69) versus (3.86 ± 0.60) in non-exposed control group. Conclusion: Serum mercury levels significantly increase in the traditional gold miners working in Abuhamed, while forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC) decrease but with no statistical significance.
