Air Pollution in China

 Forum Introduction
Kenneth Rahn Atmospheric chemist Kenneth Rahn regularly travels to China to consult with scientists there about the country's air pollution problem. Rahn took your questions about pollution in Beijing during the run-up to the Olympic Games.
QUESTIONS
Have recent Chinese government efforts to reduce the pollution been effective?
How does pollution in Beijing compare to metropolitan areas in the United States?
How does air quality in Beijing compare to previous Olympic locations?
Are pollution problems less serious in other Chinese cities?
What is the chemical makeup of pollution in Beijing?
Is there any way to find out pollution levels in a localized way?
Do the Chinese have a realistic chance of cleaning up the pollution in Beijing?
Will China's efforts to curb pollution affect air quality in the United States?
What about the three southern cities mentioned in the NewsHour story?
Do you see this as a public education opportunity?
What are the long-term effects on the Chinese population?
Does pollution stay in the lungs or get flushed out over time?
Sally James of Seattle, Wash. asks
What about the public education opportunity you face here? Cameras are going to bring ordinary Americans a jarring new view of air pollution. Are you doing anything to make sure the education can continue, like publications or curriculum kits?
ANSWERS
Kenneth Rahn responds:

Right now, I am just trying to keep up with media requests! We have just prepared a long article for the Journal of Geophysical Research, summarizing the Ph.D. work of my first student at Tsinghua University. Now I am starting to think of follow-up articles. I am available to speak to groups, however. Beyond that, I can't do much.
