In recognition of Earth Day, members of AirUCI's Social Sciences group posted an article describing their EcoGovLab project, founded at UCI in 2022 to coordinate a growing array of projects and collaborations supporting next generation environmental governance. An important goal is to help build the knowledge infrastructure needed to support next generation environmental governance — a daunting challenge requiring a multidisciplinary approach to research, data collection and sharing, journalistic dissemination of findings to a wide array of audiences, and new governmental initiatives across agencies.  Read the article

AirUCI faculty Jun Wu serves on UCI’s Comprehensive Wellbeing Initiative leadership team, formed in response to implementation of the Okanagan Charter on campus.  On Sept. 1, 2021, UCI was one of the first eight campuses in the U.S. to adopt the Okanagan Charter as a guiding and aspirational document to become a globally recognized Health Promoting University. Since then, this multidisciplinary leadership team has been working on infrastructure and strategy to move the initiative forward under the name Comprehensive Wellbeing Initiative. On April 19, UCI’s Comprehensive Wellbeing Initiative Town Hall fully introduced the initiative to the campus and shared the history and purpose of this project..

AirUCI Co-Director Sergey Nizkorodov and AirUCI collaborator Christian George of the National Center for Scientific Research at the University of Lyon, France, have published a paper in the Proceedings of the National Academy of Sciences that offers a new understanding of how hydroxide (OH) molecules help clear the atmosphere of human-emitted pollutants and greenhouse gases.  They found that a strong electric field that exists at the interface between airborne water droplets and the surrounding air can create OH by a previously unknown mechanism.  “OH is a key player in the story of atmospheric chemistry.  It initiates the reactions that break down airborne pollutants and helps to remove noxious chemicals such as sulfur dioxide and nitric oxide, which are poisonous gases, from the atmosphere,” says Christian, lead author on the study. 

The current common assumption is that sunlight is the chief driver of OH formation in the atmosphere.  Their research found that OH production rates in darkness mirror those and even exceed rates from drivers like sunlight exposure.  “Enough OH will be created to compete with other known OH sources,” said Sergey.  “At night, when there is no photochemistry, OH is still produced and it is produced at a higher rate than would otherwise happen.” " In the pure water itself, OH can be created spontaneously by the special conditions on the surface of the droplets.”  Read the article

The annual World Air Quality Report issued by IQAir was released this week and AirUCI grad student Cynthia Wong (Nizkorodov group) contributed to the report.  Cynthia held an internship with IQAir in the summer and fall of 2022 and worked on data analysis that focused on levels of PM2.5 in different regions of the world. The air quality data utilized in the 2022 World Air Quality Report was sourced from IQAir’s realtime online air quality monitoring platform which validates, calibrates, and harmonizes air quality data from monitoring stations located around the world.
