A running automobile emits exhaust gas and saises a cloud of dust particles from a road. The aim of this paper is to estimate the horizontal and vartical distributions of the exhaust gas and the amount of dust particles around the straight road on which an automobile runs making an angle of θ degrees with wind direction. Calculation is made by an electric computer applying O. G. Sutton's equation and his atmospheric stability-parameters to the next two cases. The one is the caseof an arbitrary angle of θand for example, θ is assumed to be 70°. The other is a particular case when wind blows parallel to the road (θ=0). Moreover, in the case of θ=0, the result of the calculation is compared with observed values of dust falls about horizontal and vertical distribution.
