抄録

The present study describes improvement methods for indoor microbial contamination in urban public facilities. We investigated the effects of low concentration of hypochlorous acid water on influenza virus with the tissue culture infectious dose 50 (TCID-50) assay using Caco-II cells and hemagglutination test. And experiment of applying system reducing airborne microbe to a primary school is introduced. Experimental results showed the validity on improvement of both relative humidity and airborne bacteria and fungi. In addition bactericidal effects of low concentration of hypochlorous acid water against Legionella bacteria in hot spring water as well as in distilled water are demonstrated.
