Abstract

Public health has been defined as the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals . Environmental health(or environmental hygiene) is a branch of public health concerned with all aspects of the natural and built environment that may affect human health. Other phrases that concern or refer to the discipline of environmental health include environmental public health and environmental health and protection. Disinfectants in terms of public health safety have been used to destory microorganism on non-living objects and sanitizer is a agent to decrease a level of number of microorganisms present on the surface of the abiotic material. Hypochlorous acid (HOCl) is a weak acid and dissociates to the hypochlorite ion (-OCl) and proton (H+) depending on the solution pH. Both HOCl and the -OCl are strong oxidizing agents and show germicidal activity. Previous studies have reported that HOCl is 80 times more effective to Escherichia coli and 40 times more effective to Pseudmnas spp. than –OCl. We evaluated the germicidal activity of HOCL against various pathogenic microbes. Thirty-one ATCC strains were exposed to HOCL solution at various concentrations (20, 40 and 80 ppm) for 1 minute. All the strains of bacteria, yeasts and mycobacteria were killed at 80 ppm after exposure to HOCL. The results suggest that HOCL solution could be used to effectively disinfect public areas.
