LONDON (AP) — British scientists say a heat wave has caused London's air quality to deteriorate, which could affect athletes' performances at the Olympics.
Scientists from King's College in London say pollution in the British capital has reached the highest level in six years. Recent sunshine and low winds are "exactly the conditions that can bring summertime smog to London," the environmental experts said in a statement Thursday.
They also launched a website that offers hourly air quality updates on a venue-by-venue and street-by-street basis.
London has the largest and most advanced air quality surveillance systems in Europe. Funded by the government, they are run by the King's College center, whose researchers combine air pollution science, toxicology and epidemiology to determine the impact of air pollution on health.
