Ozone in western N. America criminally blamed on Americans has long been known to come from Asia via high winds over Pacific Ocean. NOAA scientist in 2006: In a few years, ozone on US West Coast will be controlled by China. US political class has known for at least a decade that US clean air efforts are wiped out by Asia and naturally occurring Pacific high winds-Discover Mag, 2011, Oregonian, 2006

3/18/2011, "Made in China: Our Toxic, Imported Air Pollution," Discover, by David Kirby, (April 2011 issue)
..... ........................  

"Mercury, sulfates, ozone, black carbon, flu-laced desert dust. Even as America 
tightens emission standards, the 
fast-growing economies of Asia 
are filling the air with hazardous components that 
circumnavigate the globe."
 
p. 1: "University of Washington atmospheric chemist 
Dan Jaffe...and a new breed of global air detectives are delivering a sobering message to policy makers everywhere: Carbon dioxide, the predominant driver of global warming, is not the only industrial by-product whose effects can be felt around the world. Prevailing winds across the Pacific are pushing thousands of tons of other contaminants—including mercury, sulfates, ozone, black carbon, and desert dust—over the ocean each year....Much of it eventually merges 
with the global air pollution pool that circumnavigates the planet.
..............
These contaminants are implicated in a long list of health problems, including neurodegenerative disease, cancer, emphysema, and perhaps even pandemics like avian flu. And when wind and weather conditions are right,
they reach North America within days. Dust, ozone, and carbon can accumulate in valleys and basins, and mercury can be pulled to earth through atmospheric sinks that deposit it across large swaths of land....
...........
p. 7, "Perhaps the most counterintuitive traveling contaminant is ozone, commonly associated with ground-level pollution in cities. Volatile organic compounds, carbon monoxide, and nitrogen oxides from Asian cars and industry mix in the atmosphere as they cross the Pacific Ocean and convert in sunlight into ozone, a main ingredient in smog, Jaffe explains. When air with high ozone concentrations touches down in North America, it can pose the classic dangers of urban smog: heart disease, lung disease, and death.
.........
Jaffe recently coauthored a paper on Asian ozone coming to America. It found that
ozone levels above western North America creep upward every spring. “When air was coming from Asia, the trend was strongest. That was the nail in the coffin,” Jaffe says. “The increase was estimated at 0.5 part per billion [ppb] per year. But that’s huge. In 10 years that’s another 5 ppb. Let’s say the EPA orders a 5 ppb reduction and we achieve that, and yet, because of the growing global pool, in 10 years that gets wiped out. We’ll have to keep reducing our emissions just to stay even.”...

p. 9, "Asian mercury can reach western North America in as little as four days. Satellite images and atmospheric models such as these have helped Jaffe demonstrate how mercury and other emissions from China feed into a complex network of air currents that distribute pollutants across the globe."...

Added, 2006:

""The ozone on the West Coast in a few years will be controlled not by California and Oregon," Schnell (NOAA) says. "It will be controlled by China." The incoming pollution bucks a U.S. trend toward cleaner skies and water...."There's more mercury deposited in this country from outside our borders than from inside our borders," says Richard Scheffe, U.S. Environmental Protection Agency senior science adviser."...(subhead, "Impact on cleanup") 

4/13/2008, "China's mercury flushes into Oregon's rivers," The Oregonian, Shelby Wood, Richard Read; richardread@news.oregonian.com"...........

"From the Oregonian of Nov. 24, 2006" 

"Every five or six days, the winds flush out eastern China, sending dust and pollutants such as ozone precursors high over the Pacific, says Russ Schnell, observatory and global network operations director for the National Oceanic and Atmospheric Administration.

"The ozone on the West Coast in a few years will be controlled not by California and Oregon," Schnell (NOAA) says [in 2006]. "It will be controlled by China." The incoming pollution bucks a U.S. trend toward cleaner skies and water....

"Our best estimates indicate that there's more mercury deposited in this country from outside our borders than from inside our borders," says Richard Scheffe, U.S. Environmental Protection Agency senior science adviser. 

Mercury is just one of the foreign pollutants that scientists are tracking. At least one-third of California's fine particulate pollution --known as aerosol --has floated across from Asia, says Steve Cliff, an atmospheric scientist at the University of California at Davis. 

......................  
"In May this year, almost all the fine aerosol present at Lake Tahoe came from China," says Tom Cahill, a UC Davis emeritus professor of atmospheric sciences. "So the haze that you see in spring at Crater Lake or other remote areas is in fact Chinese in origin."
.....................
Cliff (UC Davis) says China's growing contribution will complicate U.S. efforts to meet annual average emissions standards."...
