How Do Information Resources Influencethe Public Environmental Risk Perception?A National Survey in China
Summary
This paper is not about microplastics — it is a survey-based study of how different information channels (social media, traditional news, government sources) shape Chinese citizens' environmental risk perception, finding that online information has the strongest effect on perceived environmental threats.
Information shapes people's psychological risk perception and attitude to governmental policies, which provides managerial insights to risk communications.Due to the variance in the content, timing, and frequency of information channels, each risk information channel gains different credibility from the public.In turn, information channels with high credibility might have a stronger effect on the public's risk perception than channels with low credibility.We conducted a nationwide survey (Asia Barometer Survey 2015) to explore citizens' fundamental understanding of general environmental risk perceptions and to examine the informational factors that influents residents' risk perception.The results reveal that environmental information exposure to netizens is strong, online information is easily accepted by citizens, and other information channels do not have significant effects.Factors such as age, educational attainment, household income, and location (urban/rural) were found to be related to the degree of risk perception, but gender was not.The provision of information over social media reshapes public risk perception by increasing self-reported knowledge, reducing trust, and making people more fearful.The study revealed the diverse effects of information sources of media on risk communication.

The impact of perceived risk of online takeout packaging and the moderating role of educational level
Researchers surveyed 336 consumers in China and found that awareness of packaging pollution risk significantly dampened their willingness to order online takeout food, with attitudes and social norms partially explaining the effect. Higher education levels sharpened this response, suggesting that better-informed consumers are more likely to factor plastic pollution risk into food purchasing decisions.
Who worries about microplastics? The relative importance of personal values and individual risk judgements / ¿A quién le preocupan los microplásticos? La importancia relativa de los valores personales y los juicios individuales de riesgo
Researchers surveyed nearly 700 people in Norway to understand what drives public worry about microplastic pollution. They found that personal values and individual risk perceptions were the strongest predictors of concern, more so than demographic factors or general environmental attitudes. The study suggests that communication strategies about microplastic risks should account for how people personally evaluate threats rather than relying solely on scientific information.
Risk Perception of Plastic Pollution: Importance of Stakeholder Involvement and Citizen Science
Researchers examine how people perceive the risk of plastic pollution and find that eight key factors — including visibility, familiarity, and severity — shape public and policy responses. Greater involvement of citizens and stakeholders in science could improve risk understanding and lead to more effective regulations.
The influence of media narratives on microplastics risk perception
Researchers examined how media narratives about microplastic pollution influence public risk perception. The study argues that accurate and balanced reporting is essential to prevent misinformation and ensure people clearly understand the risks associated with microplastics. The findings suggest that understanding public perceptions can help design better interventions to reduce plastic consumption and its associated health and environmental impacts.
