China’s Pollution is Crossing the Pacific and Becoming America’s Problem

A new study published in the journal Proceedings of the National Academy of Sciences has found that pollution from the manufacturing of American-bound products in China is responsible for between 12-24% of daily sulfate concentrations in the western US.

Don Wuebbles, who is a professor of atmospheric science at the University of Illinois, led the study. He said,

Pollution from China is having an effect in the U.S., and we need to recognize how that is affecting both our background ozone levels and also particulates that are reaching the West Coast.”

Strong westerly winds can send pollution from China across the ocean to the American west coast within a matter of days. The picture at the top is of Los Angeles on a particularly smoggy day.

About 21% of export-related pollution in China is from products headed for the US.
