| Popis: | Introduction. Fountains (office and outdoor), being small decorative structures used to improve the parameters of the human life environment, in the process of their work during the generation of a water jet, determine the creation of spray and aerosol fractions, thereby allowing the loss of a certain volume of liquid when air moves and wind carryover. The biological safety of the operation of such hydraulic structures depends on the composition of the microflora of the water in the main reservoir of the fountain, especially in the warm season. Materials and methods. For the period 2010-2020, the study of the composition of the microflora of water in the main reservoirs of the existing fountains and in the sedimented spray-aerosol mixture formed during the operation of these hydraulic structures was carried out. Results. At water temperatures above +18 °C and the absence of a disinfection system or its regular complete replacement, fountains were found to have a significant level of contamination with bacterial and fungal pathogens, including mycobacterium tuberculosis; the number of microorganisms of the E. coli group in office and open city fountains. The amount of Clostridial flora and streptococci in open fountains significantly exceeds the standard indicators (p |
