Measuring the aftermath of the devastating Los Angeles wildfires has just begun, with results showing that the city's air quality has dropped significantly to hazardous levels.
Large parts of the Pacific Palisades and Altadena (a town just north of Pasadena) have been destroyed by fire, leaving more than 15,000 buildings in smoke and toxic ash containing lead, asbestos and many other chemicals. A plume of smoke flew into the air.

These fires were a “wake-up call”, said Dr Haroula Bariaca. candidate in atmospheric chemistry at the California Institute of Technology and is part of a new nationwide effort to monitor chemicals in the air in real time. They are no longer “just about burning wood and grass,” she says. “They are urban wildfires, caused by the very materials that make up our homes and cities.”
In the aftermath of a fire, chemicals such as chlorine can damage the lungs, and lead in the air can cause major damage to the brain and nervous system, especially in children. Previous research indicates that the 2018 Camp Fire may have started the fire. killed As many as 12,000 Californians died prematurely due to the effects of toxic smoke and ash in the air.
According to Axios, standard air quality measurements do not take into account airborne particles such as lead, asbestos, and other chemicals.
