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…

Cadmium is a naturally occurring heavy metal that has become a global concern due to its widespread industrial use and persistence in the environment. Found in batteries, pigments, plastics, and as a byproduct of mining and smelting, cadmium can contaminate air, soil, and water. Human exposure primarily occurs through food, tobacco smoke, and occupational settings,…

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…

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…

Sulfur dioxide (SO₂) is a major air pollutant generated primarily from the combustion of fossil fuels and certain industrial processes. Exposure is linked to respiratory irritation, asthma exacerbation, and cardiovascular effects, while also contributing to acid rain, which damages ecosystems, infrastructure, and agriculture. Although emissions have declined in many regions due to regulations, SO₂ remains…

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…

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…

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…

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…

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…
