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…

Animal health is central to food security, public health, and environmental sustainability. The health of livestock, poultry, aquaculture species, and companion animals influences not only agricultural productivity but also zoonotic disease risks, trade dynamics, and the stability of food systems worldwide. Outbreaks of animal disease — whether highly pathogenic avian influenza, swine fever, or parasitic…

Fine particulate matter (PM2.5) is one of the most harmful air pollutants, linked to respiratory illness, cardiovascular disease, and premature mortality. Arising from vehicle emissions, industrial processes, biomass burning, and natural events such as wildfires, PM2.5 penetrates deep into the lungs and bloodstream, posing serious risks even at low concentrations. Managing PM2.5 is particularly challenging…

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…

Pressure vessels — including boilers, storage tanks, and industrial process equipment — are indispensable to modern industry but carry inherent risks if improperly designed, maintained, or operated. Failures can result in catastrophic explosions, toxic releases, or widespread service disruptions, with serious consequences for worker safety, public health, and infrastructure resilience. Regulation of pressure vessels is…

Lithium has become a strategic material in the global transition to renewable energy, powering batteries for electric vehicles, consumer electronics, and grid storage systems. Demand is growing exponentially, raising both opportunities and risks. While lithium plays a central role in decarbonization, its extraction, processing, and disposal raise concerns about environmental impacts, worker safety, and geopolitical…

Understanding aggregate exposure has become increasingly important in public health, regulatory policy, and consumer safety. Unlike assessments that focus on a single source of risk, aggregate exposure considers the combined effects of multiple routes and pathways — such as air, water, food, consumer products, and occupational environments — by which individuals may encounter a chemical…

Bovine spongiform encephalopathy (BSE), or “mad cow disease,” remains one of the most notable examples of how animal health risks can escalate into public health and economic crises. Linked to variant Creutzfeldt-Jakob disease in humans, BSE outbreaks in the late 20th century caused widespread alarm, disrupted international trade, and reshaped food safety regulation globally. The…

Country foods — the traditional foods harvested, hunted, or fished by Indigenous and rural communities — are central to cultural identity, nutrition, and food security. They provide essential nutrients, support community resilience, and reinforce connections to land and heritage. However, these foods can also present risks due to environmental contamination, overharvesting pressures, or changing ecosystems…

The media plays a pivotal role in shaping public understanding of risks, influencing how individuals perceive, prioritize, and respond to threats. Whether covering public health crises, environmental hazards, or technological innovations, media narratives can amplify accurate information — or spread misinformation that erodes trust and undermines protective action. The challenges of media and risk are…
