Isotopic composition of gaseous elemental mercury across Ontario

January 21, 2023

Natalie used the mercury passive air sampler to characterize the isotopic composition of GEM in the atmosphere across a large area for the first time. Read all about it in her new paper in J. Geophys. Res.

Adapting our flow-through sampler for microplastics

January 17, 2023

Huike Dong and Xiaoping Wang from the Institute of Tibetan Plateau Research of the Chinese Academy of Sciences have adapted our flow-through sampler for collecting microplastics from the atmosphere and have tested its performance in Lhasa. Read about it in ES&T.

Measuring KOA of volatile chemicals with the generator column technique

December 12, 2022

Another paper from Sivani’s PhD research was published in the J. Chem. Eng Data today. We show that the generator column technique can be used to measure log KOA values as low as ~4.5.

What is feasible when sampling GEM in the remote atmosphere using passive samplers?

December 12, 2022

Working with French colleagues, we tested our passive air sampler’s performance in some of the harshest environments on Earth: Dome C in Antarctica, Amsterdam Island and on La Reunion. We did not always succeed, but now we know what can be done and how to do it. Read all about it in our first paper in Env. Sci.: Atmos.

deltaUoa = -8.75 log Koa – 5.07

November 8, 2022

Building on Sivani’s large Koa database, Akshay, Sivani and Alessandro developed a new, very simple equation to predict the temperature dependence of partitioning between octan-1-ol and the gas phase. This work just appeared in a contribution to a special issue honouring Michael Abraham in the J. Solution Chem.

Dr. Baskaran now a postdoc in Norway

October 27, 2022

Congratulations to Sivani who successfully defended her PhD thesis this summer. She is now working at the Norwegian Geotechnical Institute in Oslo on the ZeroPM project.

Leslie starts new position in Brussels

October 27, 2022

Best wishes to Postdoc Leslie Saunders, who is leaving the research group to start as a Science Associate with Concawe in Brussels, where she will be working on the environmental assessment of UVCBs under REACH. Stay tuned for a number of papers over the next few month with all the cool stuff she did while with the Wania group.

Using our passive sampler to study mercury uptake in lichen

September 16, 2022

Our collaborator Fabrizio Monaci and his colleagues have studied the uptake of gaseous elemental mercury in lichen by co-locating lichen transplants and passive air samplers along spatial gradients of Hg contamination in the vicinity of the Abbadia San Salvatore mercury mine in Italy. Read about it in Environmental Pollution.

Introducing New Metrics for Long Range Transport Assessment

August 11, 2022

In a collaboration with Knut Breivik and Michael McLachlan, published by Environ. Sci. Technol. today, we introduce a novel approach to assess the potential of organic chemicals for LRT, which distinguishes between the potential for (i) dispersion, (ii) transfer and (iii) accumulation in remote environments.
