China pollution wafting across Pacific to blanket US
BEIJING (REUTERS) - Pollution from China travels in large quantities across the Pacific Ocean to the United States, a new study has found, making environmental and health problems unexpected side effects of US demand for cheap China-manufactured goods.
On some days, acid rain-inducing sulphate from burning of fossil fuels in China can account for as much as a quarter of sulphate pollution in the western United States, a team of Chinese and American researchers said in the report published by the US National Academy of Sciences, a non-profit society of scholars.
Cities like Los Angeles received at least an extra day of smog a year from nitrogen oxide and carbon monoxide from China's export-dependent factories, it said.
"We've outsourced our manufacturing and much of our pollution, but some of it is blowing back across the Pacific to haunt us," co-author Steve Davis, a scientist at University of California Irvine, said.
