Research Abstract

This study was designed to investigate the condition of indoor air pollution, personal exposure level and depreciation of indoor air pollution, and the following results were btained.
(1)Polynuclear aromatic hydrocarbons (PAHs) concentration in indoor air in Changchun City, China showed levels several tens of times higher than those of Kitakyushu City, Japan. This reason is due to the use of coal fuel for heating and cooking.
(2)The concentration levels of volatile organic compounds (VOCs) and HCHO in a newly constructed school building located in Kitakyushu City, Japan were mesaured. Five VOCs and HCHO were detected in the room in the new school building. The pollutants concentration decreased with the passage of time. However, the HCHO concentrations have a tendency to increase in summertime.
(3)The air pollution in the student smoking hail, xdiich is not a closed place, was measured. The concentrations of pollutants were of a relatively higher level than those during the lecture and lunch time.
(4)The personal exposure concentrations of NO_2 and VOCs were determined in two Asian countries. The personal exposure levels of NO_2 in Kitakyushu City were about lOppb, and those in indoor and outdoor air were also the same level. The personal exposure levels of NO_2 in Nepal were lower than those in Kitakyushu City, and a half of those in indoor air. Benzene concentration in Nepal was detected and was of a higher level than that in Kitakyushu City.
(5)When an air cleaner of Ozone type was used, the depreciation of NO and maldorous chemicals showed the effect. In the case of natural ventilation, the concentration of all chemicals decreased to the concentration level of outdoor air when the ventilation number has about 2.5 times per hour.
