Die Touristen tragen Gesichtsmasken besuchen Sie den Platz des Himmlischen Friedens im heavy Smog in Peking, China, 26. Februar 2014. Wut der Öffentlichkeit weiterhin in Peking zu steigen
Tourists wearing face masks visit the Tiananmen Square in heavy smog in Beijing, China, 26 February 2014. Public anger continued to rise in Beijing on Wednesday (26 February 2014) at the city governments failure to issue a top-level smog alert after days of heavy pollution, though the air started to clear in the evening as a cold front brought rain and wind. The Beijing Environmental Bureau removed an orange alert for smog, the second in a four-tier system, that had been in place since Friday, as the official Air Quality Index dropped from above 500 to about 460 at 5pm. The citys meteorological centre has issued 12 smog alerts since February 20. Nine were yellow alerts, the third-highest on the scale, which means people must stay indoors; three were orange, which require a halt to construction, barbecues and fireworks. But Beijing has been under public pressure to issue the highest alert, red, which calls for measures such as closing schools to minimise the impact on health.
