Summary:
Global levels of ethane and propane in the atmosphere have been underestimated by more than 50 percent, new research has revealed. These hydrocarbons are particularly harmful in large cities where, through chemical reactions with emissions from cars, they form ozone -- a greenhouse gas which is a key component of smog and directly linked to increases in mortality.”
