Fresh air on the mountains of mountains containing polluted dust originating from Asia, discharged from coal-fired power plants, car exhaust, forest fires, 'storm' dust, even from the kilns cooking with charcoal and wood.

China is considered to be the country with the highest carbon dioxide (CO2) emissions, causing a greenhouse effect and global warming. But scientists are also concerned that lesser known contaminants move from the Asian continent.

The US Environmental Protection Agency (EPA) recognizes that polluted air can travel at long distances."It is impossible to know how much of the polluted air moving at these distances and what the actual impact is ," said Bill Wehrum, an EPA scientist.
