Dioxins and the One Health Paradigm: An Interdisciplinary Challenge in Environmental Toxicology
AI summary Read the abstract
This review applies a One Health framework to examine the sources, environmental fate, and toxic effects of dioxins across human, animal, and ecosystem health. The study highlights that dioxins, as persistent environmental pollutants, accumulate through food webs and exert harmful effects even at low concentrations, and calls for integrated monitoring and policy approaches to address persistent gaps in surveillance and regulation.
Dioxins are legacy and persistent environmental pollutants that pose complex and far-reaching risks to human, animal, and ecosystem health. As unintentional byproducts of industrial and combustion processes, dioxins accumulate in the environment, biomagnify through food webs, and exert toxic effects even at low concentrations. This review applies a One Health lens to synthesize current knowledge on dioxin sources, environmental fate, exposure pathways, and toxicological impacts across species. We have critically examined existing surveillance systems, regulatory frameworks, and policy responses, highlighting both achievements and persistent gaps. A fully integrated One Health approach, linking environmental, animal, and human health domains, is essential for effective monitoring, risk assessment, and mitigation. It includes cross-sectoral collaboration, harmonized biomonitoring, evidence-based policy interventions, and transparent risk communication. Emerging evidence on climate-driven dioxin remobilization and microplastic interactions further underscores the urgency of adaptive, system-based strategies. Strengthening global capacity through such integrative approaches is vital to safeguard planetary health from these enduring contaminants. Quantitative insights and illustrative examples support these conclusions.

The study calls for integrated, cross-disciplinary approaches to address pollution as a shared threat across all domains of health.
Environmental pollution and One Health: An integrated threat to global health
AI summary Read the abstract
This review examines environmental pollution through the One Health lens, exploring how chemical contaminants, biological agents, and physical pollutants move between ecosystems, animals, and human populations. Researchers highlight that pollutants such as heavy metals, microplastics, and persistent organic compounds accumulate through food chains and disrupt biological systems across species.

Invisible Contamination: a One Health Perspective on Micro and Nanoplastics
AI summary Read the abstract
This systematic review takes a One Health approach to examine how micro- and nanoplastics affect humans, animals, and the environment as interconnected systems. The research shows that plastics accumulate across food chains and can cause toxic effects in multiple species, including humans. The One Health perspective is important because it recognizes that microplastic pollution in the environment inevitably becomes a human health problem.
