Question

NOx and O3

A city struggling with ozone pollution takes measures to reduce local NOx emissions by 10%. However, they are surprised (and disappointed) to discover that O3 levels do not decrease as a result of this change — in fact they go up! Draw a diagram and give a plausible explanation for why this might have occurred, based on local emissions. What additional regulatory steps might you recommend to safely reduce local pollution?
