Ambient air quality and health impacts of PM2.5 from US residential wood combustion Air pollution from residential wood burning contributes to thousands of premature deaths annually, with unexpected urban impacts.

New research out today in #ScienceAdvances, in which Kyan Shlipak et al. explore the health impacts of burning wood for heat across the U.S. Of note: ~8600 premature deaths w/ more urban impacts than expected, disproportionate impacts to POC www.science.org/doi/10.1126/... @science.org

NASA, Aerospace Corporation Study Sharpens Focus on Ammonia Emissions The pungent gas contributes to fine airborne particulate pollution, which endangers human health when inhaled and absorbed in the bloodstream.

Atmospheric ammonia is a pollutant of emerging concern, but its sources are not well characterized. In our recent study, we mapped ammonia around Californiaโ€™s Salton Sea at 2 m resolution using an airborne hyperspectral imager, revealing sharp spatial patterns and key emission sources.

Iโ€™m guessing you were standing next to your AQ sensor. I talked to Rami at EAC about Qatarโ€™s AQ monitoring/ forecasting during the World Cup, and figured itโ€™s worth staying in touch to learn from their lessons as LA prepares for the World Cup and Olympics too. Would be great to have you in the loop.

They should read our new study. In Los Angeles Purple Air sensors are likely more accurate than the expensive sensors. www.science.org/doi/10.1126/...
