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.
SETAC Founders Award for Frank
November 22, 2022
Frank is very honoured to have received the Founders’ Award of the Society of Environmental Toxicology and Chemistry (SETAC) at the Annual North America Meeting in Pittsburgh last week.
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.
