Increasing our understanding of coastal microplastics and mesoplastics: a comparison of sampling methodologies using volunteer researchers

Researchers compared three different methods for sampling coastal microplastic and mesoplastic pollution using trained volunteers at three locations in southern England. They found that one citizen science method, the Big Microplastic Survey, consistently detected more plastic pollution and fewer zero counts than the other approaches. The study underscores the challenge of standardizing sampling methods and the importance of enabling meaningful comparisons across global monitoring efforts.

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.

The baseline for micro- and mesoplastic pollution in open Baltic Sea and Gulf of Riga beach

Researchers established a baseline for microplastic and mesoplastic pollution along 24 beaches on the Latvian coastline of the Baltic Sea, using data collected with the help of up to 250 citizen science volunteers. They found that beaches on the open Baltic Sea contained more plastic particles than those in the semi-enclosed Gulf of Riga. The study analyzed wave patterns, currents, and tourism intensity as factors driving pollution distribution and highlights citizen science as a valuable tool for large-scale microplastic monitoring.
