Application of phytoncidal plants for improvement of ecological parameters of the air of library interiors

The results of the experiments on optimization of library room air with the help of the biological method are presented. Living tropical plants, volatile biologically active substances of which possess distinct antimicrobic properties are used for air sanitation. Their influence on change of the qualitative and quantitative microorganism composition in the air is shown. After plant placement the total number of colonies forming units (CFU) decreases by 3 times, that of staphylococcus – by 4.5 times. Air humidity increases insignificantly reaching the low limit of the comfort range for a person
