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.

Community Science-informed Local Policy: a Case Study in Pinole Creek Litter Assessment

This community science project assessed trash pollution in Pinole Creek, California, using volunteer data collection to support local policy changes. The findings are relevant to microplastic concerns because urban creek litter is a significant source of plastic debris that fragments into microplastics, eventually contaminating the water systems that communities depend on.

Governance Strategies for Mitigating Microplastic Pollution in the Marine Environment: A Review

This review assessed the sources, spread, and impacts of microplastic pollution in marine environments and evaluated existing governance strategies for addressing the problem. Researchers found significant gaps in management approaches, including limited community involvement in monitoring and a lack of standardized mitigation strategies for coastal areas. The study calls for stronger policy interventions, more citizen science initiatives, and coordinated international efforts to reduce microplastic pollution in the oceans.
