Alessia, Lisa, and Cora travelled to Washington, DC in December to present at the American Geophysical Union Fall Meeting.

Three papers published that improve our understanding of atmospheric PFAS
The group recently published three papers that improve our understanding of the abundance, sources, and fate of atmospheric PFAS.
Daniel’s paper describing PFAS in an ice core from Mt. Oxford icefield in Nunavut, Canada was recently published in ESPI. This ice core represented 50 years of deposition and showed evidence of both direct and indirect sources of PFAS to this remote location.
Stephen’s new method that allows for the measurement of total fluorine in the gas phase was recently published in ES&T Letters. Application of the total gaseous fluorine method alongside speciated measurements shows there is a large quantity of “missing” fluorine in the atmosphere, similar to previous observations in the condensed phase.
A collaborative paper reported the first in situ ambient atmospheric measurements of PFCAs. The measurements were made using acetate-CIMS and showed atmospheric formation dominated the observed PFCAs, even in urban Toronto.
To read more about Daniel’s and Stephen’s papers, see this additional context.

Paper describing off-grid atmospheric deposition samplers published
Alessia and Daniel’s work describing new automated off-grid samplers for atmospheric deposition was recently published in Atmospheric Measurement Techniques.
Check out the video abstract to see more of what these samplers can do!

Group members attend CSC meeting in Winnipeg
Lisa, Mayre, Stephen, Andrea, Na-Yung, and Cora attended the CSC meeting in Winnipeg in early June. All team members gave great presentations. Special congratulations to Lisa who received a presentation award!

Members of THE CIX team attend the AGES+ data meeting
Several members of THE CIX team attended the AGES+ data meeting in beautiful Boulder, CO in May. Cora attended, along with Na-Yung, Lisa, Stephen (CJY group), Yash (VandenBoer group), Ayo (NBD group at UBC), and Matthew (Murphy group at UofT). Exciting to see all the AGES+ data coming together!
Paper published showing (fluoro)polymers as sources of ultra-short chain PFCAs
Shira’s work describing ultra-short chain PFCAs and other PFAS found in the aqueous leachate of (fluoro)polymers was recently published in ES&T Letters.
Brown carbon paper from FIREX-AQ published
Lisa’s paper describing offline analyses of brown carbon from samples she collected on the Twin Otter aircraft during the FIREX-AQ campaign was recently published in Atmospheric Chemistry and Physics!

Group members attend Fluoros 2023
Daniel, Jessica, and Cora attended the Fluoros meeting held in Idstein, Germany from Aug 31-Sep 1.
Jessica presented her direct inject IC-MS method for ultra-short chain PFCAs and Daniel presented his analysis of PFAS in an ice core from the Canadian High Arctic. Cora presented atmospheric sampling methods from several group members, including CIMS (Shira, Ye), AIM-IC-MS (Jessica, Shira, Mayre, Eric), and total gaseous fluorine (Stephen).

Team members attend the CSC in Vancouver
Group members Eric and Stephen, as well as group alum Shira, travelled to CSC to present their work. Cora presented work from group members, including Daniel, Jessica, Alessia, Eric, and Shira.
Congratulations to Eric for winning a best student poster award for his presentation!

Welcome to new group members!
Welcome to new graduate students, Nasrin and Na-Yung, as well as new undergraduate students, Arman and Sadeya. They will all be gearing up quickly to participate in the upcoming THE CIX campaign. We are excited to have all of you as part of the team!
