Chinese air pollution clears up mystery of London's 1952 hazardous haze

In December 1952, a fatal fog crept through London for almost five days, smothering the city in a yellow haze that reeked of rotten eggs. The “Great Smog,” as it was called, caused up to 12,000 deaths and left more than 150,000 people hospitalized in the worst air pollution event in European history. The calamity sparked the British Parliament to pass the Clean Air Act in 1956, but the exact chemical processes that caused the event have remained a mystery, until now.
