Resumen |
Groups of miners working in the Donetsk mines were examined to determine the impact of hot microclimate on the pathogenic effect of mine dust. The workers were selected with regard to the following factors: length of service, length of time that dust was present in their lungs, working conditions (ambient dust levels, composition of the dust, liberation of volatile substances by the coal, depth of mining, air temperature and atmospheric pressure at workplaces in the mines). The physiological indices were: lung levels of dust, collagen, lipids, mineral impurities and free SiO2. There was a correlation between the factors characterising the pathogenic effect of the dust and the air temperature: an increase by one degree in the range 25-35°C was accompanied by an increase in lung tissue levels of dust by 9.9%, of SiO2 by 15.4% and of mineral impurities by 10.7%. The probability of the occurrence of pneumoconiosis increased by 10% for each degree above 26°C. MACs for different kinds of dusts should be reduced for hot workplaces in deep mines. |
