Abstract
Contour maps of selected 20 compounds were constructed from the results of the survey of hazardous air pollutants in Fuji city, Japan. Relationships between the locations of high concentration areas and those of emission sources were investigated.
The results obtained were as follows:
1) Benzene and formaldehyde concentrations were found to be high along the trunk roads. Contour maps of toluene and acetaldehyde concentrations were similar to those of benzene and formaldehyde.
2) PAH concentrations were predominantly affected by soot concentrations emitted from the specific factories.
3) Trichloroethylene and tetrachloroethylene concentrations were significantly affected by the stationary emission sources. Chloroform concentration was found to be high near the factories of using it. Because emission amount of chloroform is relatively small, other factors may affect chloroform concentrations.
