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 Contribution of Citizen Scientists to the Monitoring of Marine Litter

Researchers compared 40 citizen science marine litter monitoring studies with 40 professional science studies, finding that citizen science projects have mainly focused on beach surveys and successfully generated large-scale distribution data, while professional studies have contributed more to composition analysis and ecological impact assessment. The review highlights the complementary strengths of both approaches and the value of citizen participation in long-term litter monitoring.

Citizen Science for Assessment of Microplastics on Beaches: A Case Study in Mexico

Researchers used a citizen science approach involving 26 volunteers to assess microplastic abundance and type on Mexican beaches, providing broad geographic coverage at lower cost than traditional monitoring. Participants used standardized materials and training to collect and identify microplastics, generating a representative database that also raised public awareness of coastal plastic pollution.
