Laurentian SETAC Ottawa Pub Night - April 23, 2025 from 5 to 7 pm.

Title: Out of the non-stick pan, into our waters: Maternal transfer of perfluoroctane sulfonate (PFOS) in the Great Lakes' salmonid species and effects on oxidative stress levels throughout embryo development

Speaker: Geneviève Haché, Carleton University

Where: Mike's Place Pub, Ottawa, Ontario https://gsacarleton.ca/mikes-place/
Accessibility: https://carleton.ca/campus/buildings/nideyinan/

Abstract: Extensive industrial and commercial use of per- and polyfluoroalkyl substances (PFAS) has led to their widespread contamination of the Great Lakes. Previous studies suggest maternal offloading of PFOS in wild-caught Lake Michigan salmonid species. This project evaluates PFOS exposure effects throughout the development of rainbow trout eggs: a salmonid species important to the Great Lakes. We exposed rainbow trout eggs at varying concentrations of PFOS (0, 0.03, 0.3, 3,0 & 30 µg/ml in Cortland’s solution). We assessed the following markers of oxidative stress at various timepoints: lipid peroxidation levels, superoxide dismutase (SOD) activity and relative glutathione (GSH) abundance. Preliminary results show a general decrease in lipid peroxidation levels, varying SOD activity that lowers significantly in the 0.3 ppm treatment group at week 4 (76% lower than control) and an increase in GSH levels across treatments at week 4 increase (up to 11% above control). PFOS compartmentalization will be tracked through LC-MS/MS analysis of embryo content. The resulting data will provide key insight into the toxic effects of PFOS on salmonid embryo development and its mechanism of accumulation, as well as its broader environmental and ecological impact.

March is #WomensHistoryMonth! We encourage you to take time to learn about the women who have made important contributions to the sciences throughout history, such as the pioneers of toxicology shown here. Tell us about the women in science who inspire you!

Drawing of a women in a lab coat working with test tubes and Erlenmeyer flasks. Text above on a blue background says, "LSETAC celebrates Women's History Month - Let's learn about 3 trailblazing women in toxicology!"

Image of a smiling woman surrounded by drawings of test tubes on a blue background. Text says "Rachel Carson - the mother of the modern environmental movement. In 1962, Carson published 'Silent Spring', where she revealed the dangers of DDT on human health and the environment and advocated for safer chemical use. This groundbreaking work was one of the major contributing factors to the creation of the US Environmental Protection Agency."

Image of a woman and drawings of Erlenmeyer flasks on a blue background. Text says "Dr. Mary Amdur - the mother of air pollution toxicology. Dr. Amdur's research revealed the toxic effects of sulfur dioxide and trioxide from industrial sources on human health. Despite severe harassment and intimidation from industries, she continued her research. Her findings contributed to the creation of the US Clean Air Act in 1963 and shaped decades of anti-pollution research.

Image of a woman and drawings of microscopes on a blue background. Text says "Dr. Alice Hamilton - pioneer in the field of industrial toxicology. Despite facing significant barriers due to her gender, Dr. Hamilton made groundbreaking contributions by studying industrial toxic disorders, such as lead, mercury, and carbon monoxide poisoning. This work ultimately laid the groundwork for the creation of the Occupational Safety and Health Administration (OSHA).

Laurentian SETAC pub night
Title: Effects of short-chain per-and polyfluoroalkyl substances (PFAS) on northern leopard frog (Rana pipiens) developmental, physiological, and immunological responses
Speaker: Dr. Jillian Rohonczy, Carleton University
When: Wednesday, January 29, 2025 | 5:00 to 7:00 pm – talk begins at 6:00 pm
Where: Mike’s Place Pub, 209 Nideyinàn (Formerly UC) at Carleton University – 1125 Colonel By Drive, Ottawa
Abstract: The chronic toxicity of short-chain (≤ 7 perfluorinated carbons) per- and polyfluoroalkyl substances (PFAS) is relatively understudied despite their prevalence and persistence in the environment. We conducted two exposure studies to examine the chronic toxicity and bioconcentration of short-chain PFAS using northern leopard frog (Rana pipiens) tadpoles. The first exposure study examined the effects of two short-chain perfluoroalkyl carboxylic acids (PFCAs), perfluorobutanoic acid (PFBA) and perfluorohexanoic acid (PFHxA), on northern leopard frog tadpole growth and development endpoints. The second study investigated the effects of two short-chain perfluoroalkyl sulfonic acids (PFSAs), perfluorobutanesulfonic acid (PFBS) and perfluorohexanesulfonic acid (PFHxS), on northern leopard frog tadpole growth, development, stress, and immune metrics. We found that that some short-chain PFAS influence tadpole growth, hepatic health, and lipid metabolism, and can exert endocrine-disrupting effects on tadpoles during early development. These studies furthered our understanding of the effects of short-chain PFAS exposure on aquatic organisms and provided essential information for ecological risk assessments of these compounds.
