Natural Air Purifier Is More Plentiful
From Times Staff and Wire Reports
A natural chemical that scrubs pollution from the sky is more abundant than previously believed, leading scientists to wonder if they have been underestimating the atmosphere’s ability to cleanse itself.
A new study by European scientists published in the current issue of Nature shows levels of hydroxyl are probably steady or even on the rise. Hydroxyl chemically reacts with a range of polluting gases, including methane and carbon monoxide, and removes them from the atmosphere.
