Air Pollutant Concentrations and Factors Affecting Air Pollution Air inversions greatly affect local air quality because pollution is trapped. Assume an inversion occurs over a 75 m x 50 m surface area and there is no way for the pollutant to escape. There are 100 cars and each one produces 10.5 µg/s of carbon monoxide (CO). Part a [1 points]: What is the concentration (in ppm) after 1 hour if the inversion is at 150. m? Part b [1 points]: What is the concentration (in ppm) after 1 hour if the inversion is at 1,500. m? Part c [1 point]: Is the NAAQS exceeded in either case? The 1-hr concentration for CO should not exceed 35 ppm. Part d [3 points]: Describe three ways (natural or human-caused) that the concentration of CO would decrease.
C.
D.
following are the three ways to reduce the CO concentration.
