Professional Illnesses as a Result of the Effect of Heavy Metals and Toxic Substances in Miners from the Mine Lead-zinc ore "Sasa"

The exposure of the organism in an environment contaminated with heavy metals, is associated with many diseases, transient changes in the respiratory tract, lung function deteriorated, visits to emergency care and hospitalization. The results of the research, conducted with miners working in ,,Sasa’’ the mine of lead-zinc ore, were focused towards validation of existing professional risk. Most affected are the miners working jobs like mining, drilling head and ore („krupicari“),what was verified by analysis of the acute symptoms, for which we proved that are much more signified during the working ship of these jobs. According to the time of exposure, with the workers in the experimental group, we found that the most spread is the working service of exposure from 1 to 5 years working at the same place, indicating that also a short span of exposure can be dangerous for some organs, depending the individual hypersensitivity to the organism itself. The most common lung diseases in exposed workers are: chronic bronchitis and tracheitis,chronic obstructive lung disease, pneumoconiosis and silicosis. Considering the harmful effect of lead on respiratory, hematopoietic, kidney and nervous system, we can rightfully say that it is a question of so called ,,silent killer’’
