The aim of the study was to present the epidemiological characteristics, new diagnostics trends and prevention of the pulmonary diseases related to dust (PDD) in Bulgaria. Retrospective epidemiological study during the period 1980-2003 y. was done. A new cross sectional case control study of workers exposed to high concentration mineral dust and non-exposed control group in 2003 year were performed. Non patrametric, correlation analysis and linear statidstical analysis were performed. An SPSS statistical package was used. Epidemiological trends of different types of pneumoconiosis, and 11 years study of tendencies in malignant mesothelioma in the country were analyzed. A prognosis of the appearance of PDD during the future 10 – 30 years was done. A comparison between chest radiographic images and HRCT amongst pneumoconiotic patients was done. Image/functional constellations for diagnostic purposes were created. The following conclusions can be made: 1. PDD play a leading epidemiological role amongst occupational diseases in Bulgaria. 2. An appearance of pneumoconiosis and asbestos-related malignant mesothelioma in the next 10 – 20 years was expected. 3. HRCT, as well as constellation HRCT/VC, FVC and FEF50% could be more correct diagnostic methods in pneumoconioses.
