Wood smoke is a significant contributor to air pollution, especially in regions where wood burning is used for residential heating or where wildfires are prevalent. Fine particulates and toxic compounds in wood smoke are linked to respiratory illnesses, cardiovascular disease, and increased mortality. In addition to health impacts, wood smoke contributes to climate change through…

The societal risk aspects of chemical safety have become a focal point of concern for the public, governments, and the chemical industry. This concern stems from the increasing awareness of the vast number of chemicals present in everyday life, such as in household products, foods, and workplaces. Some of these chemicals have been linked to…

Contamination of water sources — whether from industrial discharges, agricultural runoff, mining, or natural events — poses significant risks to human health, ecosystems, and economic activity. Pollutants such as heavy metals, pathogens, nitrates, pesticides, and emerging contaminants like PFAS can persist in water systems, creating both acute and chronic health threats. Incidents of contamination often…

Cognitive decline, encompassing conditions such as dementia and Alzheimer’s disease, represents a growing public health challenge with profound social and economic consequences. As populations age worldwide, the prevalence of cognitive impairment is expected to rise sharply, straining healthcare systems, families, and communities. Beyond direct health impacts, cognitive decline affects workforce participation, caregiving demands, and quality…

Mitigating flood risk goes beyond response and recovery — it involves proactive strategies to reduce the likelihood and severity of impacts before disasters occur. Measures range from physical infrastructure, such as levees, dams, and green stormwater systems, to policy interventions including zoning, building codes, and managed retreat. Climate adaptation and resilience planning now make flood…

Aluminium is among the most widely used metals globally, valued for its light weight, versatility, and role in industries ranging from packaging and construction to transportation and consumer goods. Yet its ubiquity has also raised questions about potential health and environmental risks. Aluminium exposure can occur through food, water, consumer products, and occupational settings, and…

The protection of native species is central to biodiversity, ecosystem resilience, and cultural heritage. Native plants, animals, and microorganisms provide critical ecosystem services such as pollination, water purification, and soil stability. Yet these species face mounting risks from habitat loss, climate change, pollution, and invasive species. The decline or disappearance of native species not only…

Safe drinking water is a fundamental public health necessity. Contamination incidents — whether microbial, chemical, or physical — can rapidly undermine community trust and cause acute or long-term health harms. Challenges range from aging infrastructure and source water contamination to emerging contaminants such as pharmaceuticals, PFAS, and microplastics. Climate change further stresses water systems by…

Public health is the foundation of population well-being, addressing risks that range from infectious disease outbreaks and chronic conditions to environmental hazards and social determinants of health. The COVID-19 pandemic highlighted the essential role of public health systems in managing crises, but also revealed vulnerabilities in preparedness, equity, and trust. The sector’s complexity arises from…

Baby formula represents a uniquely sensitive area of food safety and nutrition, given its role as the primary or sole source of sustenance for many infants. Ensuring the safety, quality, and adequacy of infant formula is critical to supporting early childhood development and preventing health risks during a period of profound vulnerability. Contamination incidents, supply…
