A line graph, titled Amount of Air Pollution Parcticles by State, shows Parts per trillion or p p t, and Years 2006 through 2015 for Virginia, Wyoming, North Carolina, Tennessee, and Maryland. The line for Wyoming starts at 5 p p t with little change, ending just below 5 p p t. The line for Virginia starts at 13 p p t and ends at 8 p p t. The line for North Carolina starts at 13 p p t and ends just below 9 p p t. The line for Maryland starts just above 13 p p t and ends at 10 p p t. The line for Tennessee starts near 13.5 and ends at 9 p p t.
