Meaer 1 1.akik k teadr inmarka) Question I (25 Marks) (a) Consider the floor plans for the two-story home shown in Figure 1. List the six (6) criteria pollutants. For each criteria pollutant clearly identify two potential sources within the home. (12 marks) Figure 1 Floor plans two-story single detached home (b) For three (3) criteria pollutants identified in Question 1, part (a), briefly describe the strategies that could be used to minimize exposure to these pollutants. (12 marks) (c) Consider the Ozone concentration time series given in Figure 2, i) What are the three precursors to tropospheric ozone production? (3 marks) Using relevant chemical cquations account for the shape of the curve shown in Figure 2 ( 6 marks) iii) The NAAQS, for SO2, assuming a 3hr averaging time is 0.5ppm. Monitors were placed horizontally 1m from the moving traffic and 1.3m above ground level, at the front gate of the UTECH campus. The average concentration of SO2, as detected by monitors is 71g/m3 with maximum values approaching 194g/m3. How would you describe the air quality in this vicinity? (Assume relative atomic mass SO2=64,T=298K,P=1 atm, R=0.082057 L.atm. K1mol1) (6 marks)
