Manganese is an essential trace element necessary for human health, industrial processes, and steel production, yet it also poses risks when exposure levels exceed safe thresholds. Occupational exposure in mining, welding, and manufacturing, as well as environmental contamination from industrial emissions or water supplies, can lead to neurological effects, including manganism — a Parkinson’s-like disorder.…

Flooding is one of the most common and destructive natural hazards, affecting millions of people each year. Whether caused by heavy rainfall, snowmelt, storm surges, or river overflow, floods can result in loss of life, property damage, infrastructure failure, and long-term economic disruption. Climate change is intensifying flood risks by altering precipitation patterns, raising sea…

Cannabis regulation has rapidly evolved in recent years, shifting from prohibition toward medical and recreational legalization in many jurisdictions. While legalization brings opportunities for economic growth and social justice reforms, it also raises significant public health and safety questions. Concerns include impaired driving, adolescent use, product contamination, and the long-term health effects of high-potency formulations.…

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…

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…

Plant protection is essential for safeguarding global food security, biodiversity, and economic stability. Crops face threats from pests, diseases, weeds, and invasive species, all of which can reduce yields, disrupt supply chains, and increase reliance on pesticides. Climate change compounds these risks by shifting pest ranges and intensifying outbreaks, while global trade accelerates the spread…

Air quality is one of the most visible and persistent environmental health concerns worldwide. Poor air quality, whether driven by industrial emissions, transportation, energy production, or natural phenomena such as wildfires, is directly linked to respiratory illness, cardiovascular disease, and premature mortality. Beyond health, degraded air quality undermines economic productivity, reduces quality of life, and…

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,…

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…

Artificial intelligence (AI) has become a transformative force in decision-making across sectors ranging from healthcare and finance to energy, transportation, and regulation. The promise of AI lies in its ability to process vast amounts of data quickly, uncover hidden patterns, and support evidence-informed decisions in ways that humans alone cannot easily achieve. Yet the risks…
