Join us on Wednesday January 29th from 5-7pm for our first pub night of the year in Ottawa! Dr. Jillian Rohonczy (Carleton University) will present on the effects of short-chain PFAS on northern leopard frogs. Talk begins at 6pm at Mike's Place Pub. RSVP here: www.laurentiansetac.ca/event-detail...
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.
