A thermal power plant emits SO 2 at the rate of 500 × 10 8 μg/s. Its stack has an effective height of 200 m where wind speed is 5.0 m/s. If the horizontal and vertical dispersion coefficients are 400 m and 200 m, respectively, the downwind ground level concentration of SO 2 at a distance of 2 km will be:
