Objectives: The aim of this 7-year follow-up study was to determine respiratory changes in dental technicians. Material and Methods: In our region, in the year 2005, 36 dental technicians were evaluated with a cross-sectional study on respiratory occupational diseases, and in 2012 we evaluated them again. Inclusion of information on respiratory symptoms and demographic features questionnaires was applied. Pulmonary function tests (PFT) were performed. Chest X-rays (CXR) were evaluated according to the ILO-2000 classification. For the comparisons of the technicians' findings in 2005 and 2012, data analyses were performed with the Wilcoxon test in addition to descriptive statistical procedures. Results: In 2012, 19 out of the 36 technicians continued to work in the same place, so we were able to evaluate their findings. The prevalence of respiratory symptoms in dental technician was as follows: dyspnea 7 (37%), cough 6 (32%), and phlegm 5 (26%). According to ILO classifications in 2005, among the 36 technicians, 5 (13.8%) had pneumoconiosis. At the end of 7 years, there were 9 pneumoconiosis cases among the 19 remaining technicians (47%). Thus, there was a statistically significant progression on the profusion of the radiologic findings (p < 0.005). Also there was a significant worsening on spirometric findings (p < 0.05). Conclusion: In dental technicians, a determination of both radiologic and functional progressions at the end of 7 years demonstrate that the primary and secondary preventive measures are necessary for these workplaces. Workplaces must be regularly controlled for worker health and hygiene.

W artykule przedstawiono podstawowe informacje dotyczące zachorowalności na pylicę płuc w górnictwie węgla. Opisano podstawowe źródła zapylenia w kopalniach węgla kamiennego oraz najczęstsze nieprawidłowości stwierdzane podczas kontroli tego zagrożenia, zwracając szczególną uwagę na zmniejszanie emisji pyłów oraz stosowanie środków ochrony indywidualnej dróg oddechowych.

This article presents basic information on the incidence rate of pneumoconiosis in coal mining. Main sources of dust in coal mining are discussed as are the most common irregularities found during inspection of this hazard. Special emphasis is focused on a reduction of the emission of dusts and the use respiratory protective devices.

The risk of industrial dust in the work process is one of the greatest challenges not only in Europe but also in the modern world, where over a million people die each year from pneumoconiosis and other respiratory diseases. In Poland, one of the most numerous groups of employees constantly exposed to polluted air at the workplace are miners employed in hard coal mines, who in 2021 they accounted for 89.8% of all exposed persons in Poland (34,876 employees). In order to assess the impact of industrial dust hazards on the health of miners, employees of the Department of Safety Engineering of the Silesian University of Technology, in cooperation with students of the Pomeranian Medical University in Szczecin and a pulmonology specialist, conducted a pilot assessment of the effects of long-term exposure of employees of the preparatory departments of mine X to mine dust. The scope of diagnostic tests included: interview with the patient, physical and spirometric tests. Among the surveyed miners, 18.4% had various disorders and changes in the respiratory system, including the diagnosed pneumoconiosis. The article describes the health effects of long-term exposure of miners to mine dust and the partial results of the diagnostic tests.

The workers of an iron foundry were exposed to air pollution, which after some time of exposure results in lung fibrosis among some workers. The diagnosis of pneumoconiosis in workers of an iron foundry is based mainly on the radiological findings among workers exposed to the dust causing lung fibrosis. However, on radiograms many parenchymal structures overlap, which limits sensitivity and specificity to the method. Difficulties in accurate interpretation of conventional radiograms in silicosis also result from their relatively low resolution. The purpose of the present study was to assess the value and usefulness of high resolution computed tomography in the diagnostics of nodular changes in foundry workers' pneumoconiosis, compared to conventional radiography. The study group consisted of 64 iron foundry workers in whom silicosis had been recognized. The average age of the group was 51 years and the mean silica exposure time was 23 years. Chest radiograms with hard X-rays were taken at the maximal inspiration phase. For the HRCT examination the Siemens Somatom ART apparatus was used, equipped with a 512 × 512 pixels reconstruction matrix and a special programme for high resolution algorithm image reconstruction. In our material, consistency of results for conventional radiography and HRCT in revealing the presence of nodules was high. A statistically significant increase in detectability of intralobular nodules and peripheral nodules localized under the pleura was observed. The increase in detectability of cavernous, calcified nodules and those in the upper pulmonary fields obtained from computed tomography, however, was not statistically significant. High resolution computed tomography provides significant additional information in patients with foundry workers' pneumoconiosis.

Statistical data on occupational diseases recorded by the Institute of Occupational Medicine in Lodz, Poland, indicate a renewed increase in the number of cases of pneumoconiosis in Poland in recent years, especially in the PKD section of mining and quarrying industries. At the same time, in 2018 as a result of the implementation of directives of the European Parliament and the Council of the European Union, the changes were introduced to the Polish legislation in the area of protection of workers from the risk of exposure to carcinogenic or mutagenic agents related to the respirable fraction of crystalline silica found, among others, in mine dust. As a result of these solutions, since 2020 we have seen a spike in the number of miners employed in conditions of risk of carcinogenic dust. These facts indicate that despite the wide measurement of harmful factors in coal mines, the effectiveness of preventive measures taken does not bring tangible benefits, and OSH services have problems with the proper assessment of industrial dust hazards at workplaces. In the article, based on surveys, diagnostic (health) tests of workers and verification of the risk assessment methods used, the authors try to point out the most common mistakes made in estimating the level of risk associated with exposure to industrial dust.

In this article various types of dust created by mining activities have been discussed. Especially the dust which is formed during mechanical rock-cutting. Classification of particular kinds of dust considering its particle size, silicose content as well as inhalation level has been discussed and effect on the pneumoconiosis. Different ways of polish mining dust suppression have been presented and their efficiency regarding maximum allowed concentration (MAC) have been analyzed in the work security aspect.
