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. Objectives: The aim of the study was to evaluate serum mercury levels and to assess lung functions in artisanal gold miners. Material & 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�±32.24 mg/l versus 1.40�±0.94 mg/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. The FEV1/FVC ratio in the exposed men was 86% versus 89% in the control group. Conclusion: Serum mercury levels significantly increases in the traditional gold miners working in Abuhamed, while forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC) decreases.
