(1) Background: The increasing contribution of anthropogenic electromagnetic radiation has altered the Earth’s electromagnetic landscape and poses a serious problem for electromagnetic ecology and medicine. The aim of this study was to develop a working theoretical framework to describe the current state of interaction between the human body and electromagnetic fields in the external environment and to facilitate transdisciplinary collaboration among scientists in studying and addressing this problem. (2) Methods: Extensive research has been conducted in the literature to provide a comprehensive presentation of data, enabling a working concept of the interaction between the human body and electromagnetic fields in the external environment. (3) Results: General data, theoretical foundations, mechanisms, and results of the interaction of external electromagnetic fields with the human body were presented. (4) Conclusions: There is a proven interaction between the human body and external electromagnetic fields, as the body is part of the Earth’s electromagnetic landscape and has biophysical mechanisms for coupling with it. The increase in anthropogenic electromagnetic radiation is an electromagnetic environmental problem, and this requires further study of the safety issues and the impact of anthropogenic electromagnetic fields on the human body, and a reassessment of their biological impact on the human body, tightening the standards and requirements for electromagnetic safety in places where people live, a moratorium on further deployment of 5G, urgent application of the precautionary principle, and stricter exposure limits, especially for Wireless Communication Electromagnetic Fields.

The advancement of sustainable energy is a key component of the achievement of the Sustainable Development Goals. Technology advancements have made tidal current energy (TCE) a promising renewable energy source. China possesses abundant TCE resources and has gradually incorporated TCE into its energy and marine development policies. In China, TCE projects are currently being implemented on a large scale. However, despite policy-level recognition, TCE development in China has received limited regulatory attention, particularly with respect to environmental protection and ecological risk governance. Existing governance frameworks largely rely on general marine environmental and ecological policies, which are insufficient to address the three-dimensional, underwater characteristics and cumulative ecological risks. This study analyzes the evolution of China’s TCE-related laws and policies and identifies key deficiencies in current environmental regulation. To promote the sustainable TCE projects, the paper proposes tentative recommendations to promote the sustainable development of TCE in China, including the formulation of specialized environmental impact assessment guidelines grounded in the precautionary principle, future policies for addressing the cumulative environmental impact of large-scale TCE deployment, and the establishment of an environmental risk assessment system tailored to the data limitations and ecological characteristics of TCE exploitation.

Background: E-cigarette use has risen sharply among young never-smokers, largely driven by the availability of several thousand appealing flavours. This narrative review synthesises evidence on the health effects of vaping, flavour toxicology and attractiveness, designs and outcomes of flavour bans, and complementary measures. Methods: Peer-reviewed publications and institutional reports (up to January 2026) were retrieved from PubMed, Web of Science, Google Scholar, and reference lists of included articles. Evidence from about 200 references was synthesised by a multidisciplinary working group. Results: Although flavouring substances are generally considered safe for ingestion, their inhalation toxicity remains uncertain. In vitro and in vivo studies have reported oxidative stress, inflammation, cytotoxicity, impaired ciliary function, transcriptomic changes, genotoxicity, and DNA damage. These findings—along with the strong youth appeal of fruit/sweet flavours, the inconclusive effects of flavours on smoking cessation, and persisting uncertainties—support banning non-tobacco e-cigarette flavours under the precautionary principle. Flavour bans can reduce e-cigarette use and initiation, especially among young adults, although partial substitution towards combustible cigarettes has been reported in some U.S. states. Policy success requires effective enforcement, prevention of industry circumvention, curbing cross-border sales, and closing regulatory loopholes—ideally at the international level (e.g., EU-wide). Conclusions: E-cigarette flavours may increase vaping toxicity and strongly appeal to youth, justifying flavour bans to prioritise youth protection. To maximise effectiveness, accompanying measures and sustained investment in tobacco prevention, youth education, and accessible evidence-based smoking cessation support are essential. Full article

Advances in affordable genetic engineering have accelerated the creation and large-scale environmental release of genetically modified microorganisms (GMMs). While beneficial applications exist, GMMs may present unique, long-term risks to human and environmental health. Unlike static chemicals, GMMs are biologically active, self-replicating entities capable of rapid mutation and global dispersal. Current regulatory frameworks place responsibility on each country to regulate GMMs, without a clear, coordinated international policy. This review details critical risk scenarios, including horizontal gene transfer to native species and the possible disruption of vital human microbiomes (gut, oral, and infant), which could increase resistance to degradation, promote traits that expand a microbe’s range of hosts or ecological niches, and enhance the production of novel metabolites with unexpected biological activity. In soil, GMMs may support the emergence of “super bugs” or destabilize carbon sequestration cycles, potentially impacting climate resilience. Engineered microbial enzymes in the food supply may also act as environmental drivers of autoimmunity. Given the limited understanding of microbial ecology, we propose a decision-based biosafety workflow emphasizing pre-release risk assessment and continuous post-release monitoring. We urge national and international regulators to adopt the precautionary principle to better protect human health and the environment from the potential negative outcomes of GMMs. Full article

This scoping review examined published evidence linking environmental and industrial exposures to breast cancer, synthesizing studies conducted between 2015 and 2025. Using the Arksey and O’Malley framework, 51 peer-reviewed studies were identified and analyzed across five domains: study design, evidence quality, pollutant associations, geographic emphasis, and research gaps. Most studies used retrospective designs, primarily case–control, ecological, cross-sectional, and cohort approaches, which identified associations but could not establish causation. Evidence of quality varied due to heterogeneous environmental modeling methods, exposure to misclassification concerns, and unmeasured confounding, even though 86 percent of studies had sample sizes larger than 1000 cases. Pesticides, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs) were consistently associated with breast cancer, and nitrogen oxides (NOx), particulate matter (PM), and endocrine-disrupting chemicals (EDCs) also showed frequent significant associations. Research was geographically concentrated in North America and Europe, and few studies examined industrial hotspots or low-income regions. Gaps included the need for stronger epidemiological designs, multipollutant models, standardized exposure metrics, and clearer integration of significant environmental findings into public health protections. Overall, while evidence of pollution-related breast cancer risk continued to accumulate, the precautionary principle remained largely unimplemented. Advancing environmental policy, improving exposure transparency, and incorporating hotspot-based approaches are critical for reducing pollutant burdens and strengthening cancer prevention.

Inflammatory bowel disease (IBD) comprises mainly Crohn’s disease (CD) and Ulcerative Colitis (UC). The Western model suggests that environmental factors, immunological factors, the gut microbiome, and genetic disposition all contribute to the onset and sustained symptoms that define CD, although the pathogenesis of CD remains unresolved. Current studies propose that in individuals who are genetically susceptible, genetic factors linked to immune dysregulation, in combination with environmental exposure, can result in dysbiosis of the gut microbiome and intestinal barrier dysfunction, leading to immune dysregulation. In Malaysia, the incidence of IBD is rising with CD increasing disproportionally compared to UC, and the incidence of CD currently mirrors that of the United Kingdom in the 1930s, which now has one of the highest incidences worldwide. Given the suggested role of Mycobacterium avium subspecies paratuberculosis (MAP) in CD in Western countries, which is subject to some controversy, this review summarises for the first time the current evidence on genetic, environmental, and microbial factors that could contribute to the rise of Crohn’s disease in Malaysia and proposes preventive approaches. We note the increasing reliance of Malaysia on imported cattle and milk products from areas of high Johne’s Disease prevalence to meet increasing demand and changes in milk preferences in the Malaysian population, both key indicators for human-MAP exposure in the Western model. Therefore, should MAP be shown to be associated with CD in Malaysia, some preventative measures are suggested, such as screening imported and native beef and dairy cattle, dairy products and ultimately water, both recreational and potable.

The capacity of the United Kingdom (UK) to prosecute technology-enabled financial and economic crime (FEC) is increasingly shaped by the Collingridge dilemma. Even though the dilemma was broadly conceptualized in technology governance, its application to prosecutorial and enforcement practice, evidentiary standards, and criminal liability attribution represents uncharted scholarly territory. Through socio-legal mixed methods combining doctrinal analysis, case studies, and comparative analysis, the paper shows how the dilemma’s two horns or pillars (i.e., early epistemic uncertainty and late institutional inertia) manifest in criminal law and regulatory contexts. The paper finds that just like the European Union and United States, the UK criminal enforcement ecosystem exhibits both horns across cryptocurrency, algorithmic trading, artificial intelligence (AI), and fintech domains. By integrating supplementary theories such as responsive regulation, precautionary principles and technological momentum, the study advances a socio-legal framework that explains enforcement inertia and doctrinal gaps in liability attribution for emerging technologies. The paper demonstrates how epistemic uncertainty and institutional entrenchment shape enforcement outcomes and proposes adaptive strategies for anticipatory governance including technology-literate capacity building, anticipatory legal reform, and data-driven public-private coordination. These recommendations balance ex-ante legal clarity (reducing uncertainty) with ex-post enforcement agility (overcoming entrenchment) to provide a normative framework for navigating the Collingridge dilemma in FEC prosecution.

Researchers are increasingly engaged in studies to determine and correct negative welfare consequences of animal husbandry and behaviour modification procedures, not least in response to industries’ growing need to maintain their social licence through demonstrable welfare standards that address public expectations. To ensure that welfare recommendations are scientifically credible, the studies must be rigorously designed and conducted, and the data produced must be interpreted with full regard to conceptual, methodological, and experimental design limitations. This commentary provides guidance on these matters. In addition to, and complementary with, the ARRIVE guidelines that deal with animal studies in general, there is a need for additional specific advice on the design of studies directed at procedures that alter behaviour, whether through training, handling, or restraint. The COMPASS Guidelines offer clear direction for conducting welfare-focused behaviour modification research. They stand for the following: Controls and Calibration, emphasising rigorous design, baseline measures, equipment calibration, and replicability; Objectivity and Open data, ensuring transparency, validated tools, and data accessibility; Motivation and Methods, with a focus on learning theory, behavioural science, and evidence-based application of positive reinforcers and aversive stimuli; Precautions and Protocols, embedding the precautionary principle, minimising welfare harms, listing stop criteria, and using real-time monitoring; Animal-centred Assessment, with multimodal welfare evaluation, using physiological, behavioural, functional, and objective indicators; Study ethics and Standards, noting the 3Rs (replacement, reduction, and refinement), welfare endpoints, long-term effects, industry independence, and risk–benefit analysis; and Species-relevance and Scientific rigour, facilitating cross-species applicability with real-world relevance and robust methodology. To describe these guidelines, the current article is organised into seven major sections that outline detailed, point-by-point considerations for ethical and scientifically rigorous design. It concludes with a call for continuous improvement and collaboration. A major purpose is to assist animal ethics committees when considering the design of experiments. It is also anticipated that these Guidelines will assist reviewers and editorial teams in triaging manuscripts that report studies in this context. Full article

Climate change is advancing, sea levels are rising, and peak river discharges are increasing. Accelerated sea level rise (SLR) may pose a significant threat to the long-term habitability of the Netherlands. In the short term, further reinforcement of flood defenses is required. However, the key long-term question is which adaptation strategy will most effectively manage flood risk in the Netherlands. As part of the SLR Knowledge Programme, research was conducted on various long-term strategies, focusing on the feasibility of three approaches: Protect, Advance, and Accommodate. The Protect and Advance strategies aim to reduce flood risk primarily through the prevention of flooding. The Accommodate strategy, particularly in its more extreme form, emphasizes Managed Retreat, following the precautionary principle, or seeks to mitigate flood consequences rather than invest in Prevention. This study examined the economic implications of two opposing cornerstone strategies, Protect and Managed Retreat, as well as hybrid strategies that integrate elements of both, across different sea level rise scenarios. Additionally, the study includes a forward-looking assessment of the potential impacts on the financial sector, with particular attention to catastrophe insurance and capital requirements aimed at mitigating default risk. The findings indicate that a Managed Retreat strategy represents a last-resort option and cannot be implemented effectively without concurrent protective measures. Furthermore, the annual flood risk is only marginally reduced under the Accommodate strategy, even when combined with protective interventions, while its associated costs significantly exceed those of the Protect strategy. A combined approach integrating protection with localized Accommodate measures that support multi-functional land use, such as nature-based solutions and water storage, appears to offer a more promising strategy, if these values cover the costs. The results can be used to evaluate the effectiveness of possible adaptation strategies to sea level rise. Full article

This systematic review examined the health risk assessment methods of studies of whole-body vibration exposure from occupational vehicles or machines utilizing the International Standard ISO 2631-1 (1997) and/or the European Machine Directive 2002/44. This review found inconsistent reporting of measurement parameters in studies on whole-body vibration (WBV) exposure. Although many authors treat the ISO 2631-1 HGCZ as a medical health standard with defined threshold levels, the epidemiological evidence for these limits is unclear. Similarly, the EU Directive offers more comprehensive risk management guidance, but the numeric limits are equal without supporting scientific evidence. Both guidelines likely represent the prevailing societal and interdisciplinary consensus at the time. Authors note discrepancies between international and national standards and adverse WBV exposure outcomes are reported below given boundaries. Future publications should report all relevant parameters from ISO 2631-1 and clearly state study limitations, exercising caution when applying ISO 2631-1 HGCZ in health and safety assessments and considering different susceptibility of diverse populations. We advise reducing WBV exposure to the lowest technically feasible limits wherever possible and applying the precautionary principle with attention to individual differences, instead of depending solely on numeric limits.

A global debate is underway about how to achieve economic growth, which has led to a push for even greater ‘better regulation’ than already exists in the US and UK, including Scotland. ‘Better regulation’ can include softer regulation, less regulation, or even deregulation. Another regulatory model involves the precautionary principle and there is tension between the two. The ‘better regulation agenda’ has influenced the environmental quality standards adopted for emamectin benzoate in Scottish sea lice treatment. To explore how these complex regulatory models have been used or advocated for and why over 25 years, a process tracing analysis focusing on Scottish Government and Parliament web entries was conducted. Such an analysis has both strengths, providing new perspectives, and weaknesses, regarding the possible quality and extent of information available. The results reveal the ‘better regulation’ model in practice was initially adopted in the 2000s, supported by Scottish Government advisors and implemented by its regulators. Gradually, however, the model was challenged, at times, by researchers, regulators, Members of the Scottish Parliament, environmental non-governmental organizations, and by investigative journalists. This resulted in new environmental quality standards on emamectin benzoate being proposed, then sometimes tightened or blocked. Hence, ‘better regulation’ remains highly influential in the sector, with the fish farming industry able to weaken precautionary policies and enforcement in practice, directly and indirectly.

Per- and polyfluoroalkyl substances (PFASs) have gained significant attention due to their widespread distribution in the environment and potential adverse health effects. While ingestion, especially through contaminated drinking water, is considered the primary route of human exposure, recent research suggests that other pathways, such as inhalation and dermal absorption, also play a significant role. This review provides a concise overview of the toxicological impacts of both legacy and emerging PFASs, such as GenX and perfluorobutane sulfonic acid (PFBS), with a particular focus on their effects on the liver, kidneys, and immune and nervous systems, based on findings from recent in vivo, in vitro, and epidemiological studies. Despite the transition to PFAS alternatives, much of the existing toxicity data focus on a few legacy compounds, such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), which have been linked to adverse immune outcomes, particularly in children. However, evidence for carcinogenic risk remains limited to populations with extremely high exposure levels, and data on neurodevelopmental effects remain underexplored. While epidemiological and experimental animal studies supported these findings, significant knowledge gaps persist, especially regarding emerging PFASs. Therefore, this review examines the visceral, neural, and immunotoxicity data for emerging PFASs and mixtures from recent studies. Given the known risks from well-studied PFASs, a precautionary principle should be adopted to mitigate human health risks posed by this large and diverse group of chemicals. Full article

Background/Objectives: Auditory capacity plays a fundamental role in human emotional development from prenatal stages and persists as the last sensory modality to fade during terminal phases. In palliative sedation, uncertainty about preserved hearing—despite potential unconsciousness—underscores the need to evaluate current care recommendations for this critical sensory dimension. This review examines European guidelines to (i) assess auditory care integration in palliative sedation protocols and (ii) propose humanization strategies for sensory-preserving end-of-life care. Methods: Narrative review of evidence from the European Palliative Sedation Repository and the European Association for Palliative Care (EAPC). Results: Three key findings emerged: (i) lack of explicit protocols for auditory care despite acknowledging environmental sound management (e.g., music, family communication); (ii) limited consensus exists regarding hearing preservation during unconsciousness. Conclusions: Although auditory perception during palliative sedation remains scientifically uncertain, the precautionary principle warrants integrating auditory care into palliative sedation through (i) family education on potential hearing preservation; (ii) therapeutic sound protocols; and (iii) staff training in sensory-inclusive practices. This approach addresses current gaps in the guidelines while enhancing patient dignity and family support during end-of-life care. Further research should clarify auditory perception thresholds during sedation. Full article

This commentary evaluates contemporary equestrian sport governance through the lens of equine welfare science. Drawing on evidence from the FEI Sport Forum 2025 debates, the IFHA Racing Integrity Handbook, media coverage of horse sport, recent scientific presentations, regulatory texts, and published research, we identify systemic shortcomings in how horse welfare is assessed, prioritised, and protected. Key issues include reliance on performance as a proxy for welfare, inadequate “fit-to-compete” protocols, neglect of horses’ mental states, coercive tack and equipment practices (e.g., double bridles, tight nosebands, ear hoods), pharmacological and surgical interventions that mask pain, euphemistic regulatory language (e.g., whip “encouragement”), and inconsistent implementation of welfare rules. Through a series of case studies, from dressage and show jumping forums to racing integrity handbooks, we illustrate euphemistic language, defensive group dynamics, dismissive rhetoric towards evidence-based criticism, and a troubling “stable blindness” that sidelines the horse’s perspective. We conclude that meaningful reform requires (1) embedding validated behavioural and physical welfare indicators into all competition and pre-competition protocols, (2) transparent, evidence-inclusive rule-making under a precautionary principle, (3) genuine engagement with independent equine welfare experts, and (4) establishment of empowered, impartial oversight bodies to ensure that stated codes of conduct translate into consistent, enforceable practice. Only by catering to the horse’s subjective experiences and applying modern ethological and bioethical standards can equestrian sport retain its social licence and ensure integrity in all areas of competition management.

As lithium demand increases, lithium brine from hyper-arid salt flats is becoming increasingly important, although there are concerns about its extraction’s impact on the local water balance. Water footprinting could address these impacts, yet studies lack consensus on whether to classify brine as water or a mineral. This study aims to review perspectives on lithium brine accounting within and beyond the water footprint context, focused on the Salar de Atacama, Chile, and to establish accounting principles for water footprinting, following the relevant ISO standard. Outside water footprinting, four perspectives on brine classification are identified: hydro-social/perceptual, molecular–thermodynamic, precautionary, and legal. Adopting some of these perspectives, e.g., the rationale of brine’s molecular–thermodynamic similarity to freshwater, some water footprint studies argue for accounting brine as equivalent to freshwater. However, they are a minority. According to ISO, brine should not be classified as freshwater, and the type of water and its functionality should be distinguished. We suggest some saline waters below a specific salinity threshold may function as freshwater and could be included in freshwater accounting. Additionally, lithium brine extraction can induce effects on surrounding water compartments. Since conventional water footprints overlook such local effects, we propose testing a set of site-specific accounting principles through case studies. Full article
