Abstract |
Indoor air qualities vary depending on a number of factors, inclduing outdoor air pollution, indoor air pollutants,reactions between different pollutants, ventilation efficiency, and air penetration of building's wall. NO2is distributed widely in a house as an indoor air pollutant. Heating apparatus and cooking stove discharge high concentrations of NO2. A stove without a smoke pipe such as space-heater and central heating system with an air supply equipment also discharge NO2. In addition, smoking cigarette is a source of NO2 emission. The term nitrogen oxide is typically referred to any binary compound of oxygen and nitrogen or to a mixture of such compounds. Among the nitrogen compounds, NO and NO2 are the most harmful compounds. Especially, NO2is more harmful than ozone, aldehyde, ketone, and nitric acid, so an intensive study on NO2 is needed. We surveyed the concentration of NO2 in a class room, a laboratory, an office room, smoking and non-smoking rest rooms, and a computer room to reduce indoor air pollution. |
