(Phys.org) -- The Great Smog of London is often upheld as a time when pollution reached appalling levels: over a four-day period in December 1952, the capital came to a standstill, cars were abandoned, airports closed and over 4,000 people died due to respiratory or cardiovascular problems. But what might come as some surprise is that roughly the same number of people died as a result of pollution in London in 2008.
