These shows evidence that it has been a lot of change in the air quality results but the charts show less reducing regulations because there are fewer pollutants in the air. The levels of carbon monoxide, lead and nitrogen dioxide had dropped because there is less of it in the air so the "change" is less because there is less to be changed thanks to the improvement on air polluting regulations.
