Could Air Pollution Be Causing More Traffic Accidents?

Poor weather, cell phones, radios, alcohol, and jerks: we think of these as some of the most common causes of car accidents. However, scientists at the London School of Economics say that air pollution, of all things, should be added to that list.
Researchers say they looked at 5 years’ worth of data and found that when levels of nitrogen dioxide (NO2) rose just a microgram per cubic meter, the number of car crashes increased by 2%. [1]
