Road To Nowhere: Asphalt May Be More Polluting Than The Cars That Drive On It

A new study reveals roads may be producing more air pollution than the vehicles that drive on them.

Yale University researchers found that numbers didn't add up when they tried to account for all the sources of existing air pollution in Los Angeles.

According to Science Magazine, the researchers turned to newly-paved asphalt roads and roofs, which up until now had been overlooked in such studies.
