In June 2005, media coverage of the health effects of asbestos used at factories on nearby residents developed into an “asbestos panic” in Japan. Asbestos is a natural mineral fiber and is widely used as a material for industrial and construction purposes because of its significant tensile strength, heat resistance and thermal insulating properties. Japan′s Ministry of Health, Labor and Welfare has proposed a new regulation for the prevention of asbestos scattering due to building demolition. Here, we provide a brief overview of asbestos from the viewpoints of present and future problems.

To test the idea that concentration of air pollutants such as NOx, CO and SPM is significantly increased in enclosed spaces frequented by automobiles, an investigation of air pollution at a 52-space underground parking lot was carried out. Average concentrations of NO2, NO, CO, SPM and HCHO were 103ppb, 221ppb, 8.7ppm, 20.7μg/m3 and 18.0ppb respectively. Concentrations of NOx and CO were significantly higher than outdoors. Correlation between NOx and CO concentrations and the number of parking cars was not high, because the automobile sources of the pollutants were immediately present.
