Plastic Pellets in the Sandy Sediment of Beaches on the Middle Coast of Rio Grande do Sul, Brazil

This study evaluated plastic pellet (nurdle) abundance in beach sediments along the middle coast of Rio Grande do Sul, Brazil — a region with low urbanization — and examined how proximity to the port of Rio Grande affected pellet density. Pellets are pre-production plastic granules that escape into the environment during manufacture and transport, and serve as a direct indicator of industrial plastic pollution pathways.

Occurrence, distribution, and associated pollutants of plastic pellets (nurdles) in coastal areas of South Texas.

Plastic pellets (nurdles) were found at 24 sites along the south Texas coast, and analysis revealed they accumulated polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and other chemical pollutants from their environment. Nurdles act as concentrators and vectors for toxic chemicals, raising concerns for marine life and human health in coastal communities.

Microplastic Pollution in the Coast of Tarragona, Spain: A Western Mediterranean Study

Researchers, including students as part of a citizen science project, collected and analyzed water and sand samples along the Tarragona coast of Spain, finding that tiny microplastics under 3mm dominated sea water samples and that plastic pellets — called nurdles — made up over half the anthropogenic waste by weight found in beach sand. The study highlights significant microplastic contamination in a Western Mediterranean coastal zone.

Citizen Science for Monitoring Plastic Pollution from Source to Sea: A Systematic Review of Methodologies, Best Practices, and Challenges

This systematic review examines how citizen science programs track plastic pollution from land to sea. The research found that while public participation greatly expands data collection, inconsistent methods and data quality issues limit the scientific usefulness of the results. Better-designed citizen science programs could help communities monitor and respond to the microplastic pollution in their local environments.
