Can we shop ourselves to a clean sea? An experimental panel approach to assess the persuasiveness of private labels as a private governance approach to microplastic pollution

An experimental consumer survey in Norway, Germany, and Portugal found that people are willing to pay a premium for products certified as microplastic-free, suggesting that private certification schemes could be an effective market-based tool for reducing microplastic pollution. However, willingness to pay was influenced by country, trust in certifiers, and how the certification was framed.

Nudging consumers about the issue of microplastics: an experimental auction study on valuation for sustainable food packaging

Researchers used an experimental auction to study whether informing consumers about microplastic pollution changes how much they are willing to pay for sustainable food packaging. They found that consumers offered significantly more for pasta products packaged in biodegradable materials with environmental footprint labels, especially after learning about microplastic risks. The study suggests that transparent labeling combined with consumer education could be an effective way to shift purchasing behavior toward more sustainable options.

Microplastics in seafood: Consumer preferences and valuation for mitigation technologies

A consumer survey in Chile found that people were willing to pay about US$4 extra for mussels certified to have 90% lower microplastic content, and informing consumers about health risks increased that price premium by 56%. This signals a market opening for microplastic mitigation technologies in seafood and highlights how public awareness of health risks can drive demand for cleaner food products.

Microplastics in seafood: Consumer preferences and valuation for mitigation technologies

A consumer study in Chile found that people were willing to pay significantly more for mussels certified to have reduced microplastic contamination, with information about health risks increasing willingness to pay by 56%. However, combined health and environmental information also made some consumers less likely to buy mussels at all, suggesting that microplastic awareness could reduce seafood consumption. These findings highlight the economic importance of developing microplastic mitigation technologies for the seafood industry.

Filling Discrepancies between Consumer Perception and Actual Piped Water Quality to Promote the Potable Use of the Municipal Water Supply in Indonesia

This paper is not about environmental microplastics in an ecological or health context; it studies consumer trust and drinking water preferences in Indonesian cities to encourage tap water use over bottled water, with the plastic waste angle being secondary and policy-focused rather than scientific.

Public Willingness to Pay for Sustainable Consumption: Case of Bioplastic Medical Masks

This paper is not relevant to microplastics research; it uses a discrete choice experiment to measure consumers' willingness to pay for bioplastic medical masks, focusing on sustainable purchasing behavior rather than microplastic pollution science.

Perceptions about potential microplastic interventions: a study on knowledge, concerns, and willingness to pay

Researchers surveyed Oregon residents about microplastic pollution and found that fewer than 25% were willing to pay full price for washing machine filters that capture plastic microfibers before they reach waterways, suggesting that government subsidies and targeted outreach to early adopters may be needed to scale up this promising pollution prevention tool.

Analysis of intention to purchase environmentally friendly packaging in the city of Ribeirão Preto, Brazil

Despite its title referencing environmentally friendly packaging, this paper is a consumer behavior survey studying what factors drive Brazilians to intend to buy eco-friendly packaging — not original research on microplastic pollution or its effects. It examines environmental concern and personal values as predictors of purchasing decisions and is not directly relevant to microplastic contamination or human health.

Early screening of suspected microplastics in bottled water in the Santiago Metropolitan Region of Chile

Researchers screened multiple brands of bottled water sold in Santiago, Chile, for microplastic contamination using fluorescence microscopy. They detected suspected microplastic particles in all tested brands, with concentrations varying significantly between products. The findings add to growing global evidence that bottled water, often perceived as a cleaner alternative to tap water, may be a meaningful source of human microplastic exposure.

Drivers of green purchasing behaviour: a systematic review and a research agenda

This systematic review of 41 studies found that environmental concern, health consciousness, social influence, and perceived value are the strongest drivers of green purchasing behavior. While not directly about microplastics, the findings are relevant to understanding what motivates consumers to choose plastic-free or reduced-plastic products.

The Impacts of Environmental Knowledge on Aqua Product Purchase: The Role of Environmental Concerns

Researchers examined how environmental knowledge and environmental concerns influence bottled water purchasing behavior among residents of Bandung, Indonesia, focusing on the Aqua brand as a proxy for plastic-packaged aqua products. Results indicate that stronger environmental awareness correlates with altered purchase decisions, highlighting the role of consumer education in reducing plastic consumption.

Everyday storage and handling of PET bottled water increase human exposure to nano- and microplastics: Influence of socio-economic factors

Researchers tested eight major U.S. bottled water brands and found that everyday conditions like heat exposure and shaking dramatically increased nano- and microplastic release from PET bottles, with nanoparticle concentrations rising over ninefold under combined heat and agitation. A survey of over 1,600 people in Nebraska revealed that higher awareness of microplastics and education levels correlated with behaviors that reduce exposure, such as avoiding bottled water storage in hot conditions.

Microplastic in Food and Water: Current Knowledge and Awareness of Consumers

This study surveyed 410 highly educated young consumers and found that while awareness of microplastics in food and water is growing, significant knowledge gaps remain about contamination sources, exposure levels, and associated health risks.

Is the public really concerned about microplastics? The importance of measuring everyday relevance and behavioral intentions as well as stated concern

Researchers surveyed over 2,200 citizens in Germany and Italy to examine whether public concern about microplastics translates into everyday relevance and behavioral change. While stated concern was high in both countries, most people reported thinking or talking about microplastics only rarely, though they still expressed willingness to take action to reduce exposure. The study found that both stated concern and everyday relevance mediated the link between knowledge about microplastics and intentions to change behavior.
