Titanium is valued for its strength, light weight, and corrosion resistance, making it indispensable in aerospace, medical devices, construction, and consumer goods. While titanium itself is generally considered safe, its extraction, processing, and use in certain forms raise potential health and environmental risks. Occupational exposures to titanium dusts and nanoparticles, as well as environmental impacts…

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…

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…

Legal metrology — the regulation of measurement in trade, safety, and compliance — underpins trust in markets and everyday transactions. From weighing goods in grocery stores to calibrating medical devices, fuel pumps, and utility meters, accurate measurement ensures fairness, safety, and accountability. Failures in measurement systems can erode consumer confidence, distort markets, and introduce risks…

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…

Drug safety is a cornerstone of modern healthcare, ensuring that medicines deliver therapeutic benefits while minimizing risks of harm. Adverse drug reactions, drug interactions, counterfeit products, and manufacturing quality lapses all pose significant challenges. At the same time, the rapid pace of pharmaceutical innovation — from biologics to gene therapies — creates both opportunities and…

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…

Nuclear energy is one of the most powerful and controversial sources of electricity in the modern world. It offers a low-carbon alternative to fossil fuels, supporting climate change mitigation, but also raises enduring concerns about reactor safety, radioactive waste, proliferation risks, and public trust. High-profile accidents, such as Chernobyl and Fukushima, have shaped global perceptions,…

Public transport systems are critical to economic productivity, urban mobility, and environmental sustainability, but they also present complex safety, health, and operational risks. Accidents, infrastructure failures, overcrowding, and infectious disease transmission all pose potential threats to passenger safety and public trust. Meanwhile, climate change adds further stress, with extreme weather events disrupting services and damaging…
