Across Southern California, people are taking precautions as the air quality index — a measure that includes fine particles — reached hazardous levels for some neighborhoods, including Pasadena. Air purifiers in Home Depots around Central Los Angeles are sold out.

The fires burning across Los Angeles County have sent billowing plumes of black smoke into the air, posing a major health threat even as quick-moving flames have blowtorched homes, schools and other buildings. That’s because wildfire smoke contains fine particulates, known as PM2.5, which are one-seventieth the width of a single human hair and can easily infiltrate the heart and lungs. While the fires are currently concentrated on the West Coast, the threat isn’t limited to that region. Residents nationwide need to be cautious because wildfire smoke can travel, said Susan Anenberg, chair of the environmental and occupational health department at George Washington University.

In 2006, Kareena Lynde was working in Shasta Lake, California, on a hotshot crew — a group of highly trained wildland firefighters — when she started to notice a sharp pain in her abdomen. At first she chalked up the discomfort, plus symptoms like bloating and nausea, to the nature of her work, with its long, arduous hours and unhealthy backcountry meals. (Kutz, 1/9)
