Summary
How do microplastics impact aquatic ecosystems? What can happen if an entire food web of aquatic organisms is exposed to microplastic contaminants?
Garth Covernton, a researcher who studies the interactions between microplastic pollution and aquatic ecology, joins the podcast today to enlighten us on these critical questions…
Garth is a University of Toronto Arts and Sciences Postdoctoral Fellow working in the Rochman lab and the McMeans lab as part of the pELAstics project. Through his work, Garth is on a mission to "provide conservation managers and policymakers with the simplified frameworks required to protect aquatic ecosystems".
Join us now to learn about:
- The types of freshwater that Garth is conducting his research in.
- What food webs are, and what they can tell us about microplastic contamination.
- The most commonly used and produced polymers that contaminate aquatic systems.
- The mechanisms of analysis used to determine how microplastics move through different ecosystems.
- Animals that are more at risk for ingesting microplastics.

| 0:00.0 | when I'm working on involves food webs. |
| 0:02.5 | And so I'm really interested in actually, |
| 0:04.4 | like the structure of who is eating |
| 0:06.5 | who was in an aquatic system. |
| 0:09.5 | So if you think of a lake, |
| 0:11.0 | you often have these like small zooplighting |
| 0:13.6 | they're feeding tiny little microscopic algae. |
| 0:17.0 | Those zooplighting are being eaten |
| 0:18.8 | by smaller or medium sized fish. |
| 0:21.3 | And then those fish are being eaten by overfish. |
| 0:23.8 | And that's what we kind of call it food web. |
| 0:25.6 | And there's this interconnectivity. |
| 0:27.4 | And also in there you have these other |
| 0:29.4 | like insect larvae and things swimming around |
| 0:31.6 | or in the sediments. |
| 0:32.8 | There's all forms of food web. |
| 0:34.2 | But a lot of our understanding so far |
| 0:35.9 | of how microplastics invites. |
| 0:38.3 | Forget frequently asked questions. |
| 0:40.1 | Common sense, common knowledge, or Google. |
| 0:42.6 | How about advice from a real genius? |
| 0:44.8 | 95% of people in any profession |
