Summary

This study applied a ray-tracing particle tracking model to numerically simulate how microplastics of varying sizes and densities are transported through Saguenay Fjord, a deep stratified fjord system in Quebec. Accurate transport simulations are essential for predicting where microplastics accumulate in aquatic food webs and ultimately reach the fish and seafood that humans consume.

Microplastics are ubiquitous pollutants in oceans, rivers, lakes, estuaries, and coastal areas, and pose a serious threat to aquatic ecology and natural ecosystems. Predicting the fate and transport of microplastics in these water systems, which are typically driven...
