Environment

Pollution

Smog and smoke clouds that now frequently plague California and other parts of the West are making breathing more dangerous for residents of the region, according to a new study.

Researcher Deepti Singh of Washington State University, Vancouver and colleagues found that exposure to ground-level ozone and the fine-particle pollution from more frequent wildfires has increased by 25 million “person days” from 2001 to 2020.

Short-term effects from the pollution include breathing difficulties and worsening heart and lung diseases, such as asthma. Exposure to both types of pollution at the same time compounds the health risks, and long-term exposure can have even far more serious consequences. The study found that in August 2020, 86% of the western U.S. was blanketed by extreme amounts of both.
