Tons of sand turned Beijing's sky orange Saturday as the strongest sandstorm this year hit northern China.
A thin dusting of sand covered the capital, causing workers and tourists to muffle their faces in vast Tiananmen Square. The city's weather bureau gave air quality a rare hazardous ranking.
Air quality is "very bad for the health," China's national weather bureau warned. It said people should cover their mouths when outside and keep doors and windows closed.
China's expanding deserts now cover one-third of the country because of overgrazing, deforestation, urban sprawl and drought. The shifting sands have led to a sharp increase in sandstorms, the grit from which can travel as far as the western United States.
The Chinese Academy of Sciences has estimated that the number of sandstorms has jumped sixfold in the last 50 years to two dozen a year.
The latest sandstorm also hit the Chinese regions of Xinjiang and Inner Mongolia and the provinces of Gansu, Shanxi, Shaanxi and Hebei, affecting about 250 million people over an area of 312,000 square miles, the state-run New China News Agency reported.
As the sandstorm moved southeast, South Korea's national weather agency issued an advisory for Seoul and other parts of the country.
Chun Youngsin, a researcher at the Korea Meteorological Administration, said the storm would produce "the worst yellow dust" this year.
Some flights at Beijing's international airport were delayed but eventually took off, said a woman answering phones at the airport hot line.
Skies cleared in the city by midday, but a warning of more dusty weather remained.
"I think this kind of natural disaster is caused by human activity, but I don't know the exact reason, and I don't know exactly what we can do to prevent this," said Beijing resident Shi Chun- yan.
China has planted thousands of acres of vegetation in recent years to stop the spread of deserts in its north and west, but experts have said the work will take decades.
And the pressures of China's development aren't easing. "Arid and semiarid areas can only support one or two people per square kilometer [about 0.4 square mile]. In China, population density in these areas is over 10 people per square kilometer," Jiang Gaoming, a professor at the Chinese Academy of Sciences' Institute of Botany, wrote for the online environmental magazine China Dialogue in 2007.
The residents once were nomads, "but now they have settled, increasing the pressure on the environment and inevitably damaging it."
The worst recent sandstorm to hit Beijing was in 2006, when about 300,000 tons of sand were dumped on the capital.
