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.

Citizen science in environmental and ecological sciences

This review describes how citizen science, where non-professional volunteers help collect data, is being applied in environmental and ecological research. Citizen science projects have contributed to monitoring pollution, biodiversity, and water quality across large geographic areas. The approach is relevant to microplastic research because trained volunteers can help sample and catalog microplastic contamination across many locations that professional scientists cannot cover alone.

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.
