Outline of Final Research Achievements

Observations of air pollutants have been carried out by the filter pack method in the wide area monitoring network consisting of the Ministry of the Environment and institute for environmental studies of local government. Atmospheric optical black carbon concentrations came to be measured in recently developed optical measurement method (Integrating sphere type optical black carbon particle measurement method), and the PTFE filters used for particle monitoring in the filter pack method were reused as the measurement samples.
Comparisons of this optical measurement method and the thermal optical reflectance method were carried out. Atmospheric black carbon concentrations were measured by reusing the PTFE filters collected from 18 sites around the country. Regional characteristics, seasonal variation of black carbon and relationship of black carbon and particle concentration measured by filter pack method were examined.
