PFAS measurements for the Whale Initiative at Tadoussac, Quebec

During the month of June 2022, I was fortunate to participate in field work alongside Alessia Colussi in Tadoussac, Quebec. The area is located on the north shore of the St. Lawrence. We traveled from Toronto to Quebec City via plane and drove from Quebec City directly to Tadoussac, taking a ferry to cross the Saguenay Fjord. This fieldwork is a part of the Whale Initiative launched by the government of Canada on improving our knowledge on the transport and deposition of contaminants, such as per- and polyfluoroalkyl substances (PFAS), in at-risk whale habitats. PFAS have been found to be problematic due to their persistence in the environment and harmful effects on mammals, including whales. The field site, called the Hovington Farm, contained instruments such as a Medium Volume Particle Sampler for the collection PFAS in the atmosphere and Precipitation Collection Units for the collection of PFAS from wet and total deposition. In addition, the field site had passive samplers for the collection of gas-phase perfluoroalkyl carboxylic acids (PFCAs), a sub-class of PFAS. Unique to passive samplers is their low cost and lack of the need of a power source, making them ideal for remote areas and large spatial scale deployment. Our goal at the Hovington Farm was to test and ensure the instruments were functional and perform any required maintenance. We also started a new sampling period for Medium Volume Samplers, Precipitation Collection Units and Passive Samplers by swapping new samples. In addition, we trained the new local site operators from Explos-Nature on how to properly exchange the samples for new upcoming sampling periods. They were very lovely people and we had full confidence in them after our training. Overall, I really enjoyed this field work experience. While we were not fortunate to see any whales, I had the opportunity to take a hike at the beautiful Saguenay Fjord National Park and to eat delicious French-Canadian food.
