Introduction: Biochemical and physiological mechanisms by which lead affects the cardiovascular system by increasing blood pressure are still unknown. But it is believed that the increased arterial pressure disturbance is caused as a result of the concentration of intracellular calcium ions (Ca). Aim of the study:The study had the purposes of analyzing the effect of lead in blood pressure at the mine workers in Trepca Stan Terg comparing years worked in the mine. Material and methods: The study included 55 workers at Stan Terg Trepca mine, out of which 44 are direct employees who work within the galleries of the mine and 11 workers outside the galleries of the mine, The Control Group. Results: From the data provided in the study, it is noted an increase of arterial blood pressure value (Systolic and Diastolic) at workers who have worked directly in the mine gallery in comparison with The Control Group. Discussion: Workers with the longest time worked in the mine have the most pronounced increase of arterial blood pressure values than those with less working experience. Lead affects the blood pressure and is closely dependent on the workplace and the years worked in the mine. Conclusion: Protective measures are necessary in prevention of lead poisoning in the workplace.
Key words: Blood pressure, Lead, Miner.
