a Consider a release of toxic pollution due to a chemical plant explosion. The point source Gaussian plume model may be used to obtain an estimate of toxic pollutant concentrations resulting from the release. The following information about the chemical release and atmospheric conditions have been identified: Emission rate of toxic pollutant = 53 tons in 75 min (1 ton = 2000 lb) Actual stack height, h = 32 m Plume rise, Ah=5.5 m Anemometer windspeed (at 10 m height) = 2.92 m/s Clear night (< 3/8 cloudiness) . . Consider a community living 3.5 km downwind of the plant and 200 m from the plume centerline. Determine: The atmospheric stability class b. The windspeed, uh (m/s), at the effective stack height H (assume rough terrain) c. The horizontal and vertical dispersion coefficients, Oy (m) and oz (m) d. The pollutant concentration at ground level, C(x,y) (ug/m?), to which the community will be exposed.
