    Screening technique to estimate high benzo[a]pyrene concentrations near roads

    The emission factors of benzo[a]pyrene for gasoline cars and for diesel cars were measured by directly collecting the exhaust gas using a portable sampling equipment and became 660 ng km–1 and 1700 ng km–1, respectively. The regression equations to easily evaluate the concentrations at the roadsides and at the crossroads were introduced as the functions of building height, road width, ...
