A survey of 73 hazardous air pollutants was performed at 35 sampling sites (including nine air monitoring stations) in Fuji city in August and December 1999. Target compounds were 14 aromatic hydrocarbons (BTXs), 39 polycyclic aromatic hydrocarbons (PAHs), 10 aldehydes and 10 volatile organohalogen compounds (VOHCs) . Main results in the survey were as follows: 1) Benzene concentrations were high along the main street, suggesting that these concentrations were affected by motor vehicle emission. 2) PAH concentrations at specific sites in the city were higher than the other sites. This suggests that PAH concentrations were affected by the specific stationary emission sources. 3) Aldehyde concentrations were high along the north part of the main street in summer, whereas they were high along the south part of the main street in winter, suggesting that these concentrations were affected by wind direction. 4) Chloroform, trichloroethylene and tetrachloroethylene concentrations were affected by the stationary emission sources, such as chemical factories, metal surface treatment plants. 5) The nine monitoring stations were suitably located to get mean levels for various hazardous air pollutants in Fuji city.
