"SANTA CRUZ, Calif. — Wildfires churning out dense plumes of smoke as they scorch huge swaths of the U.S. West Coast have exposed millions of people to hazardous pollution levels, causing emergency room visits to spike and potentially thousands of deaths among the elderly and infirm, according to an Associated Press analysis of pollution data and interviews with physicians, health authorities and researchers.
Smoke at concentrations that topped the government’s charts for health risks and lasted at least a day enshrouded counties inhabited by more than 8 million people across five states in recent weeks, AP’s analysis shows.
Major cities in Oregon, which has been especially hard hit, last month suffered the highest pollution levels they’ve ever recorded when powerful winds supercharged fires that had been burning in remote areas and sent them hurtling to the edge of densely populated Portland.
Medical complications began arising while communities were still enveloped in smoke, including hundreds of additional emergency room visits daily in Oregon, according to state health officials."
