Fine particles in wildfire smoke more harmful to human respiratory health than other pollutants Researchers at Scripps Institution of Oceanography at UC San Diego examining 14 years of hospital admissions data conclude that the fine particles in wildfire smoke can be several times more harmful to human respiratory health than particulate matter from other sources such as car exhaust. While this distinction has been previously identified in laboratory experiments, the new study confirms it at the population level. This new research work, focused on Southern California, reveals the risks of tin...

In Southern California, pollutants from wildfire smoke caused up to a 10% increase in hospital admissions. Researchers say there's a need for better air monitoring and public health programs.

 E-Mail Researchers at Scripps Institution of Oceanography at UC San Diego examining 14 years of hospital admissions data conclude that the fine particles in wildfire smoke can be several times more harmful to human respiratory health than particulate matter from other sources such as car exhaust. While this distinction has been previously identified in laboratory experiments, the new study confirms it at the population level. This new research work, focused on Southern California, reveals the risks of tiny airborne particles with diameters of up to 2.5 microns, about one-twentieth that of a...

Wildfire smoke particles cause more lung damage than other pollution sources By (0) New research suggests that particulate matter in wildfire smoke is more dangerous to human health than particles found in other types of air pollution. File Photo by Etienne Laurent/EPA-EFE March 5 (UPI) -- The fine particles in wildfire smoke are up to 10 times more harmful to human lungs than pollution from other sources, such as car exhaust, an analysis published Friday by the journal Nature Communications found. Every 10 microgram-per-cubic meter increase in particulate matter -- the hazardous microscopi...

SAN JOSE, Calif. — Choking smoke from record wildfires blanketed Northern California last summer and fall. It turned Bay Area skies an otherworldly orange, raising health concerns over a hazard that is increasing as temperatures continue to climb and poorly managed forests burn out of control each year across the West.
