Learning from the last decade of microplastics research in the Laurentian Great Lakes

Stormwater runoff studies show that low-income and commercial areas contribute significantly higher amounts of macro-litter and microplastics to the Great Lakes, highlighting the need for targeted waste management.

Lisa Sonnenburg manages cultural resources for the Lake Superior National Marine Conservation Area, documenting and protecting submerged archaeological landscapes through collaboration with Indigenous communities.

The Synthetic Collective's collaboration between scientists and artists has raised awareness of plastic pollution in the Great Lakes through exhibitions, data visualization, and the discovery of plastiglomerate.

Harris Phiri, a retired fisheries director from Zambia, shares his extensive experience in Lake Tanganyika research and his passion for conservation and interacting with the global aquatic science community.

The Clean Shores, Great Lakes project mobilized thousands of volunteers to clean up plastic litter from Tanzanian shorelines, using citizen science to identify hotspots and advocate for policy change.

Plastic pollution is a full life-cycle issue, from fossil fuel extraction to end-of-life, with significant impacts on the Great Lakes and human health, requiring systemic solutions beyond just recycling.

Research reveals that microplastics can trigger the release of substances from cyanobacteria, altering buoyancy and potentially fueling harmful algal blooms, creating a complex nexus between plastics and algae.

The IJC's Great Lakes Science Advisory Board is developing coordinated frameworks for monitoring microplastics and assessing their ecological risks in the Laurentian Great Lakes basin.
