Fewer motorists in Arizona and Nevada following the states’ stay-at-home orders appears to be improving the air quality and decreasing the effects vehicle emissions have on the environment.

Both states released their reports Monday after at least a week under the states’ respective stay-at-home orders. U.S. Environmental Protection Agency officials say particulate matter and nitrogen dioxide are pollutants that contribute to smog and poor air quality and are emitted from the transportation sector, including cars, trucks, commercial aircraft and railroads. Environmental officials say more study is required.
