Citizen science against the plastic soup: background, motivation and expectations of volunteers studying plastic pollution on Dutch riverbanks

Researchers surveyed 122 citizen scientists in the Dutch Clean Rivers project before and after one year of monitoring plastic pollution on riverbanks, finding that participants were predominantly middle-aged, highly educated, and motivated by activist goals of tackling plastic pollution at its source, while more personal motivations such as learning and enjoyment declined significantly over the participation period.

Comparison of the macro-, meso- and microplastic pollution in French riverbanks and beaches using citizen science with schoolchildren

Researchers conducted a citizen science initiative with French schoolchildren to compare macro-, meso-, and microplastic pollution across 86 riverbank and beach sites, finding that riverbanks accumulated distinct plastic assemblages compared to beaches. The study demonstrated that schoolchildren can generate reliable comparative litter data, and highlighted rivers as underrepresented yet critical plastic transport pathways to the ocean.

Sharing communication insights of the citizen science program Plastic Pirates—best practices from 7 years of engaging schoolchildren and teachers in plastic pollution research

The Plastic Pirates citizen science program in Germany engaged schoolchildren and teachers in monitoring plastic pollution in rivers over seven years, and this paper shares the communication strategies that made the program work at scale. Effective participant recruitment, guidance, and feedback loops enabled the program to generate peer-reviewed scientific data while building environmental literacy. The lessons offer a replicable model for using citizen science to expand microplastic monitoring coverage beyond what professional researchers can achieve alone.

Plastic Hotspot Mapping in Urban Water Systems

A simple citizen science method for mapping plastic hotspots in urban waterways was tested in two Dutch cities, finding similar average plastic densities but different spatial distributions. The study highlights the need for long-term monitoring to better understand how cities contribute to plastic pollution in rivers and oceans.

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.

A nationwide assessment of plastic pollution in the Danish realm using citizen science

Researchers conducted a nationwide citizen science assessment of plastic pollution across Denmark, Greenland, and the Faeroe Islands, with approximately 57,000 school students collecting 374,082 plastic items across eight nature types in 94 of 98 Danish municipalities. The study demonstrated that student-led citizen science can fill important knowledge gaps in land-based plastic litter monitoring beyond beach surveys.

Psychological outcomes from a citizen science study on microplastics from household clothes washing

Researchers conducted a pre-registered three-month citizen science study in the Netherlands where participants used microfiber-capturing laundry bags and completed pre/post surveys on environmental concern, perceived responsibility, and washing behavior. High baseline environmental concern was found but did not strongly predict behavior change, suggesting psychological interventions beyond awareness are needed to reduce laundry microfiber emissions.

Plastic Detectives Are Watching Us: Citizen Science Towards Alternative Single-Use-Plastic-Related Behaviour

This study used citizen science initiatives to engage the public in reducing single-use plastic consumption two years after the start of the COVID-19 pandemic. Researchers found that most existing citizen science projects focused on beach clean-ups and litter surveys, while none addressed consumer behavior directly. Their "Plastic Detective" project collected behavioral data on plastic use and found that young people were particularly receptive to adopting alternatives to single-use plastics.
