Pollutants From Fossil Fuels
In the United States, motor-vehicle exhaust accounts for about 60% of all CO emissions and as much as 95% of CO emissions in cities. Fortunately, emission-control devices have reduced CO levels by about 40% because the early 1970s. CO does not build without limit in the atmosphere, because it is removed by microorganisms in the soil.
