The evaluation of carcinogenic risk is important from the point of view of the development of health status and socioeconomic conditions. The research focused especially on coal miners,workers in tunneling,the ceramic industry,workers in metallurgy and workers in stone processing.The authors focused of the following spheres of the research project: 1. The epidemiological evaluation of the incidence of malignant tumours in groups of coal miners exposed to dust with low and high concentrations of quartz. 2.The verification of the carcinogenicity of dusts from coal mines and processing of stone by inhalation experiments on rats.3.The biomonitoring of carcinogenic risk with use of the selected biomarkers in group of exposed emloyees (coal workers in quarrying and stone processing).4. The histopatological investigation of autoptic materials of dead coal workers and workers in stone processing.
