CANADALAND Carney Cuts The Scientists Who Test For Toxins
20 snips
Mar 3, 2026 Shirley Tagalik, a community researcher who runs the Akumivik Society in Arviat, Nunavut, blends Inuit knowledge with Western science. Christine Bishop, a retired federal ecotoxicologist with decades at Environment and Climate Change Canada, explains contaminant monitoring. They discuss microplastics testing, community-led sample collection, long-term national monitoring, and what losing lab capacity means for public safety and policy.

Episode notes
One Lab Is The Country's Contaminant Hub
- A single ECCC ecotoxicology lab analyzes contaminants nationwide and could shrink from nine PhD scientists to one.
- That central hub processes samples (bird stomachs, tissues) that inform policy and health decisions across Canada.
Grad Student Demonstrates Microplastics Testing
- Sam toured the lab and watched a grad student scan microplastics from Great Shearwater samples into an FTIR machine.
- The student handled tens of samples showing pencil-eraser sized plastics found in gull stomachs collected across Canada.
Tissue Testing Reveals Food Chain Plastic Risks
- The polymer lab detects micro- and nanoplastics in tissues, revealing human-health risks from eating contaminated fish and mammals.
- Machines can identify polymers in muscle or liver from polar bears, walrus, and fish without locating each particle.
