airborne particulate matter
high volume air sampler
The concentrations of 1-nitropyrene and benzo(a)pyrene were measured in a airborne particulate matter（APM）collected with high-volume air sampler through four seasons in a region of Tokushima city, and relations between seasonality and main source of 1-nitropyrene and also those of benzo(a)pyrene were examined.
The concentrations of APM were highest in winter and lowest in summer. 1-Nitropyrene concentrations range from 0.19 to 0.51 μg/g（APM）and seasonality,with highest in summer and lowest in autumn were found. Benzo(a)pyrene concentrations range from 3.60 to 6.65 μg/g （APM）and seasonality, with highest in winter and lowest in summer, which are mainly related to APM seasonal variations, were found, suggesting the contribution of a heating as a source of benzo(a)pyrene besides moter vehicle exhaust.
According to 1-nitropyrene seasonality, which are closely resemble to seasonal variations of lead and vanadium contents in APM than those of APM contents, main source of 1-nitropyrene is supposed to come from moter vehicle exhaust.
