Use of scientific evidence to inform environmental health policies and governance strategies at the local level
Summary
Researchers examined how scientific evidence informs environmental health policies at the local governance level, finding gaps between available research on emerging contaminants like microplastics and their translation into effective regulatory strategies.
A major public health challenge facing local administrations is reducing the preventable burden of non-communicable diseases making cities more resilient against environmental threats. The objective of this work was to conduct a synthesis of scientific evidence relating to the local context and implement a translational process to support the Department of the Environment in order to improve integration with concurrent policy sectors to urban health and sustainability goals. The first phase reviewed the studies on the association between environmental risk factors and human health and on the contamination levels of the environmental matrices; the second phase synthesised the data in key messages according to the concerns formulated with the collaboration of the Environmental Department. A total of 31 studies were assessed: 21 investigated environmental risk factors, and 9 measured the presence of pollutants in the environmental matrices. The findings identified air and noise pollution as the most important threats associated with respiratory and cardiovascular diseases, together with significant contamination levels of the urban environment from microplastics and hydrocarbons. Based on the review findings, a layman's report for the City Council and the citizens, explicitly addressing emerging issues, was made publicly accessible. A lack of specific, updated and exchangeable data for city health profiling in a deteriorated environmental context represented the main barrier to a resilient community. The suggested recommendation for the local administration was to adopt an environmental policy integration framework to strengthen the monitoring of the impact on citizens' health.

Human Health, Environmental Quality and Governance Quality: Novel Findings and Implications From Human Health Perspective
Researchers assessed microplastic contamination in urban street runoff during rainfall events, finding particle concentrations 10-fold higher than in dry-weather flows. Road markings, tire wear, and litter were identified as the dominant source categories.
Time to strengthen the governance of new contaminants in the environment
Researchers argue that despite existing laws, hundreds of emerging environmental contaminants — including microplastics — remain unregulated, posing serious risks to ecosystems and human health. They propose a global roadmap combining proactive chemical identification, risk assessment, and international collaboration to close the governance gaps before harms become irreversible.
Editorial: Bridging the Gap between Policy and Science in Assessing the Health Status of Marine Ecosystems
This editorial introduces a research collection focused on bridging the gap between policy and science in assessing health impacts of environmental contaminants including microplastics. It highlights the need for better integration of scientific evidence into regulatory and public health decision-making frameworks.
Bridging the gap between microplastic research and social awareness of microplastic pollution through science communication: A call for action
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.
Microplastics: A Review of Policies and Responses
This critical review assembled current knowledge on policies and regulatory responses to plastic pollution globally, including legislative measures, economic instruments, and voluntary commitments. The authors identify a gap between scientific evidence and policy action and call for stronger, more coordinated international governance of plastic pollution.
