Risk assessment consists of the following 4 components, hazard identification, dose-response assessment, exposure assessment and risk characterization. Main purpose of exposure assessment is to clarify the exposure level of a target population to hazardous chemicals during their daily lives. Indoor monitoring is necessary to get an accurate exposure level, but technologies for indoor monitoring are not yet fully developed. Therefore, it is essentially needed for exposure assessment to develop analytical methods suitable for monitoring of hazardous air pollutants including carcinogens and mutagens. This paper describes some progress of technologies for monitoring carcinogens and mutagens in outdoor and indoor air.
Main items are as follows.
