			 The incident is especially embarrassing at a time when China seeks 
			to build Shanghai into a global business hub on par with the likes 
			of London, New York and Hong Kong by 2020. 
 			On Friday afternoon, the Shanghai government issued its severest 
			health warning as the city's pollution index ranged between 23 times 
			and 31 times the levels recommended by international health 
			officials.
 			In the first such advice since a new health warning system was 
			launched in April, authorities urged residents to stay indoors and 
			asked factories to either cut or halt production. 						
			
			 
 			"I don't think it's fit for people to live in this kind of 
			environment," said Shanghai resident Fan Jianjun, 34, who wore a 
			face mask as he walked through the opaque air in the Lujiazui 
			financial district.
 			"But I have no choice. I still need to work. I can only take 
			preventive measures, but I have no idea whether they work."
 			Air quality in cities is of increasing concern to China's 
			stability-obsessed leaders, anxious to douse potential unrest as 
			more affluent citizens turn against a growth-at-all-costs economic 
			model that has polluted much of the country's air, water and soil.
 			The government has announced many plans to fight pollution over the 
			years but has made little apparent progress.
 			Most of the flights leaving Shanghai's Pudong International Airport 
			have been delayed, according to the airport's website. Pudong was 
			the world's third busiest cargo airport in 2011, data from the 
			Airports Council International shows.

			Hazardous air pollution forced schools to shut or suspend outdoor 
			activities in at least two cities in eastern China on Thursday. Some 
			schools in Shanghai cancelled outdoor activities on Friday, as well.
 			The unusually noxious haze was caused by several factors, including 
			industrial pollution and auto emissions trapped by cold, windless 
			weather, said Xu Bin, an associate professor at Shanghai's Tongji 
			University.
 			By 0700 GMT, the level of PM2.5 particulate matter, or tiny 
			particles in the air that are the most hazardous to health, reached 
			a "severely polluted" 466, according to the Shanghai government's 
			monitoring website, 
http://www.semc.gov.cn/aqi/home/English.aspx.
 
 			A similar measure by the U.S. consulate in Shanghai showed a reading 
			of 503, a level described as being beyond the index on its website 
			http://www.stateair.net/web/post/1/4.html.
 			Levels above 300 are considered hazardous, while the World Health 
			Organization recommends a daily level of no more than 20.
