Marine microplastic pollution & misinformation in the public sphere: a systematic review
AI summary Read the abstract
This systematic review examines how scientific findings about marine microplastic pollution are communicated to the public, identifying gaps where misinformation can take hold. Accurate public understanding of microplastic risks matters because it drives consumer choices and policy decisions that affect human health protection.
Marine microplastic pollution is a persistent global issue that has gained scientific attention for over two decades. Nevertheless, knowledge gaps remain, particularly in how inconsistencies in communicating scientific evidence can lead to misinformation. A systematic review was conducted to identify how previous research has examined miscommunication about microplastics in the public sphere. Of the 274 scientific publications identified, 15 were found eligible for inclusion in the study. These publications were analysed to establish (i) the methodologies employed to investigate microplastic communication in the public sphere, (ii) how existing information contributes to microplastic miscommunication, and (iii) what level of awareness and knowledge around microplastic pollution has been established. Our analysis revealed two primary study types: participant-based (e.g., via surveys, focus groups) and text-based studies of media content (e.g., newspapers, digital platforms). The participant-based studies showed misperceptions about impacts on human health and their pathways into the natural environment, even among well-informed or professionally involved individuals. The text-based studies revealed inexact media reporting involving scientific referencing, content accuracy, representation of microplastic pollution, and sensationalist tones. The findings highlight the need for further research into the miscommunication of microplastic pollution to facilitate best practice in the communication of scientifically accurate information across audiences.

Researchers surveyed 1,681 respondents globally and found significant uncertainty about microplastic health risks not only among the general public but also among scientists who study plastics, reflecting the genuine knowledge gaps in current research on microplastic hazards.
From Ocean to Table: How Public Awareness Shapes the Fight Against Microplastic Pollution
AI summary Read the abstract
This literature review synthesized global studies on public awareness of microplastic pollution, finding that while scientific knowledge has expanded significantly, public understanding and behavioral change remain limited. The study identified effective communication strategies and policy approaches to bridge the gap between scientific evidence and public action.
The influence of media narratives on microplastics risk perception
AI summary Read the abstract
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.
Bridging the gap between microplastic research and social awareness of microplastic pollution through science communication: A call for action
AI summary Read the abstract
Researchers examined the gap between scientific knowledge of microplastic pollution and public awareness, calling for improved science communication strategies. The study found that despite an enormous body of research documenting microplastics in soil, water, air, and organisms, effective translation of these findings into public understanding and policy action remains inadequate.
Internet User Awareness Assessment on the Impact of Microplastics on Health
AI summary Read the abstract
A survey of 281 internet users aged 15–50 across diverse demographics assessed public awareness of microplastic health risks. Results revealed significant gaps in understanding — most respondents had heard of microplastics but underestimated their prevalence in food and water and were unaware of specific health effects. The study highlights that public health messaging about microplastics lags well behind the scientific evidence, which matters because consumer behaviour and policy support both depend on informed public understanding.
