Microplastics are widespread pollutants, but few studies have linked field prevalence in organisms to laboratory uptakes. Aquatic filter feeders may be particularly susceptible to microplastic uptake, with the potential for trophic transfer to higher levels, including humans. Here, we surveyed microplastics from a model freshwater shrimp, common caraidina () inhabiting the Crocodile River in South Africa to better understand microplastic uptake rates per individual.

- Microplastic pollution in aquatic environments, especially in freshwater systems of the Global South, is a growing concern due to rapid production and inadequate waste management.
- A study of microplastic dynamics in the Crocodile River, South Africa, revealed highest concentrations during the cool-dry season in surface water and hot-dry season in sediment, with dominant shapes being fibres and fragments.
- The findings suggest that wastewater is a significant source of microplastics, which poses risks to both local residents relying on the river for drinking water and the aquatic ecosystem.
