Abstract

Polluted indoor air has a direct impact on the student’s well-being and health. Polluted air causes suffocation, headache, sweating, decreased mental capacity, drowsiness, etc. There are many methods of cleaning the air in classrooms. Such methods include: airing the room, wet cleaning, installing ventilation, and so on. Phytoncidal properties of plants affect the reduction of the number of harmful microorganisms in the air. Therefore, the study of the effect of indoor plants on the microflora of the air in classrooms is relevant. The ability of certain types of plants to purify the air has been studied. Based on the obtained results, a list of necessary plants for placing in classrooms was formed. It has been experimentally proven that the following plants will have the most positive effect on the microbiological state of the air: Chlorophytum crested, Indoor lemon, Cytofortunella microcarpa, Sprenger’s asparagus. It was established that the main parameters (temperature and humidity) of the microclimate of classrooms meet hygienic standards and are optimal for classes. It was established that the presence of plants in the room helped to reduce the content of microorganisms from 1818 CFU to 455 CFU in 1 m3 of air. However, on the 10th day of the study, an increase in the number of microorganisms to 1667 CFU was observed. Accordingly, the species composition of plants was adjusted. The results of the study proved the positive effect of indoor plants of group 2 on the microbiological condition of the studied classrooms. The conclusion is confirmed by the decrease in the number of microorganisms in the air. The implementation of the developed recommendations for the landscaping of classrooms in an educational institution will contribute to reducing the level of microbiological pollution in the air of closed premises.
