Hygienic Ranking of Coal Dust by Biological Effects in the Inhalation Experiment
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2019, Vol 16, Issue 1
Abstract
Modern methodology for managing the risk of occupational diseases of dust etiology is implemented in the form of monitoring compliance with the hygienic regulations of industrial aerosols and proposals for regulating dust exposure doses, as a measure of “protection by time” [1]. At the same time, high rates of dust occupational diseases among coal industry workers require improving the strategy of hygienic dust hazard management. impact based primarily on clinical and hygienic data on the health status of workers, but also on a broader use of the results of an experiment to assess the biological effects of dust from fossil coal. Within the framework of the above tasks, we analyzed the results of an inhalation experiment to assess the effect of dust of 3 types of fossil coal: anthracite of different petrographic composition (vitrinite - Avitr. And fusinite - Afyuz); coal of various degrees of sintering (energy - KUener. and Coking - Kukkoks.); brown coal: with a predominance of humic acids (BUgk) and with a higher yield of fulvic acids (BUfk) [2] All dust was low-ash with a content of free silicon dioxide - 0.14-2.18%. The generated dust concentrations in the dust chambers ranged from 270 to 380 mg /m3 the dispersion of anthracite dust (by mass of the fine fraction measured by a twostage gravimetry instrument) was 25%, and brown and brown coal: 42.0 - 59.6%
