My collaborators in University of Iowa Chemistry have led a new study on siloxanol partitioning, based on measurements of ambient gases and particles from our summer 2022 field deployment in New York City.

Our collaborators at the University of Colorado Boulder have some excellent new work on chamber experiments for oxidation of "D5" decamethylcyclopentasiloxane.

Our final report is out. By Stanier, Arinze Okoye, Sheng (Jerry) Wang, and Addi O'Grady.

On Wednesday, July 24, 2024 the Iowa Institute for Public Health Practice, Research and Policy held a webinar on wildfire smoke in Iowa. We have posted a recording of the event here.

Ozone, nitrogen dioxide, and PM2.5 estimation from observation-model machine learning fusion over S. Korea: Influence of observation density, chemical transport model resolution, and geostationary remotely sensed AOD

Led by Chris Brunet of Heri Hornbuckle's research group, this paper summarizes the VMS measurements from the rooftop field campaign in summer 2022 at CUNY in Manhattan, specifically in Harlem. The title is "Concentrations of Volatile Methyl Siloxanes in New York City Reflect Emissions from Personal Care and Industrial Use"

Activity around Iowa City in March on the topics of air quality and wildfire, catalyzed the Facing the Inferno exhibit at Pentacrest Museums

We pull together all of the aerosol observations from the Zion site of the Lake Michigan Ozone Study 2017, and comment on the absence of a detectable ultrafine mode in lake spray aerosol.

Canada’s seemingly endless wildfires in 2023 introduced millions of people across North America to the health hazards of wildfire smoke. While Western states have contended with smoky fire seasons for years, the air quality alerts across the U.S. Midwest and Northeast this summer reached levels never seen there before.

Wildfires in Canada have caused a smoky haze over the Old Capitol dome, leading to an air quality advisory in eastern Iowa. Charles Stanier, an expert in airborne contaminants, explains the causes and impacts of the poor air quality, including short-term health risks and long-term effects on outdoor activities. The AirNow website and app provide information on daily air quality.
