e) (5 marks) Using the dispersion equation, calculate the likely concentrations of the particulates (PM10) at 600m and 2km downwind of the factory? C(x,y)=UHyzQexp(2z2H2)exp(2y2y2) Information you will need - Emission of PM10 (which in this case is the same as the PM2.5 that was from part c) Q converted to g/s - Neutral (stability class D) - Effective stack height (H):60m - Wind speed at effective stack height (UH):8m/s - receptor is directly downwind from the stack so y=0
