This allowed them to directly measure air pollution's dependence on population in four of the planet's major air pollution regions: the United States, Europe, China and India. More specifically, the scientists focused on nitrogen dioxide, or NO2, which is a common pollutant from the burning of fossil fuels. The gas is also a precursor to the formation of near-ground ozone, which can cause respiratory problems and is an issue in many major cities.
