THE DOWNSIDE OF THE BOOM
China's Poison for the Planet
By Andreas Lorenz and Wieland Wagner
Can the environment withstand China's growing economic might? As one of the planet's worst polluters, Beijing's ecological sins are creating problems on a global scale. Many countries are now feeling the consequences.
The cloud of dirt was hard to make out from the ground, but at an altitude of 10,000 meters (32,808 feet), the scientists could see the gigantic mass of ozone, dust and soot with the naked eye. In a specially outfitted aircraft taking off from Munich airport, they surveyed a brownish mixture stretching from Germany all the way to the Mediterranean Sea.
These kinds of clouds float above Europe for most of the year and they've traveled far to get there. By analyzing the makeup of particles in the cloud, European scientists were able to identify its origin. "There was a whole bunch from China in there," says Andreas Stohl, a 38-year-old from the Norwegian Institute for Air Research.
Some 12,000 kilometers (7,500 miles) to the west, Steven Cliff is slowly winding his way up Mount Tamalpais near San Francisco in his RV. The 36-year-old researcher has installed a complex instrument to measure the air from Asia that reaches the West Coast of the United States over the Pacific Ocean.
Days like this are ideal for taking these measurements. San Francisco is shrouded in cool fog, but up on the top of the mountain there's warm sunshine. Indeed, these are ideal conditions for surveying air currents untainted by local influences. But Cliff is alarmed by his instrument's readings -- soot particles have colored the device's filter "blacker than we've ever seen it," he says.
Back in a lab at the University of California at Davis, Cliff and his colleagues analyze the origins of the air pollution with the help of x-rays. According to their "chemical signature," most have come from coal-fired Chinese power plants, Chinese smelters and chemical factories, as well as from the tailpipes of countless Chinese diesel-powered cars and trucks.
