HYGIENIC GROUNDING FOR PREVENTIVE SANITARY-TECHNICAL MEASURES WITH SYLVINITE UNITS EXPLOITATION

Aim. To carry out hygienic estimation of dynamics of the basic medical factors of saline units (SU) while their exploitation for the purpose of grounding preventive sanitary-technical works. Materials and methods. Saline microclimatic wards “C” (SMW “C”) of different exploitation periods (to 1 month, from 1 to 2 years, and more than 2 years) were studied. By means of hygienic methods, the main medical factors including saline aerosol concentration, radiation background, aeroionization were determined. Microbial landscape of the air by the total microbial number, presence of mycelia and yeast fungi as well as golden staphylococcus with inoculation of the corresponding media was estimated. Results. Dependence of physical factors of internal environment on operation life of sylvinite units was found. Increase in the period of saline units’ exploitation caused decline in air aeroionization. In a year after SMW exploitation, mycelia and yeast fungi having a marked allergenic effect on patient’s organism were detected. Conclusions. To correct the main therapeutic factors, additional air preparation and mechanical treatment of reaction surface of the mineral is to be carried out in 1 year after SU exploitation.
