The environment in which people live, work and interact has a profound impact on health and well-being. Environmental risk factors ranging from air and water pollution to climate change, chemical exposures and unsafe housing contribute significantly to the global burden of disease. According to the World Health Organization, nearly 24% of all global deaths are attributable to modifiable environmental factors. These risks often interact with social, economic and behavioral factors to disproportionately affect vulnerable populations, particularly in low- and middle-income countries. As such, addressing environmental determinants of health through preventive public health measures is not only a scientific and policy imperative but also a matter of environmental justice and human rights. Understanding and mitigating environmental risks through informed, evidence-based public health interventions is essential to creating healthier, safer and more equitable communities [1].
Environmental risk factors encompass a wide range of physical, chemical and biological hazards present in the environment. One of the most pressing concerns is air pollution, which remains a leading cause of respiratory and cardiovascular diseases, particularly in urban areas. Fine particulate matter (PM2.5), nitrogen dioxide (NOâ??) and ozone are known to exacerbate conditions such as asthma, bronchitis, stroke and heart disease. Long-term exposure to air pollutants has also been linked to adverse pregnancy outcomes and reduced life expectancy. Preventive measures include the implementation of clean air regulations, emission control standards for industries and vehicles and promotion of cleaner energy sources such as solar and wind. Urban planning that promotes green spaces, public transportation and reduced reliance on fossil fuels also contributes to improving air quality.
Water quality is another critical determinant of health. Contaminated water supplies can lead to outbreaks of waterborne diseases such as cholera, typhoid and dysentery. Industrial waste, agricultural runoff and inadequate sanitation systems contribute to the degradation of freshwater sources. Preventive strategies in this domain include the development of safe drinking water infrastructure, routine water quality monitoring, sewage treatment and hygiene promotion. Programs like point-of-use water purification and community water fluoridation have been particularly successful in improving health outcomes in resource-limited settings. Exposure to hazardous chemicals such as heavy metals (lead, mercury), pesticides and industrial pollutants also poses serious health risks. These substances can cause neurological disorders, developmental delays, reproductive problems and cancers.
Children, pregnant women and occupational workers are particularly vulnerable. Regulation of chemical use, environmental monitoring, enforcement of safety standards and community awareness campaigns are essential to minimize exposure. For example, global efforts to phase out lead in gasoline and paints have significantly reduced blood lead levels in children over recent decades. Climate change represents a growing environmental threat with wide-ranging health impacts. Rising temperatures, extreme weather events and changing disease vectors contribute to increased cases of heat-related illness, malnutrition and vector-borne diseases like malaria and dengue. Preventive public health measures in this context include strengthening climate-resilient healthcare systems, early warning systems for natural disasters, surveillance for emerging infectious diseases and public education on climate adaptation strategies [2]. Occupational environments also influence exposure to environmental risks. Workers in industries such as mining, agriculture and construction are often exposed to dust, chemicals and physical hazards.
Implementing occupational safety protocols, providing protective equipment and conducting regular health screenings are important preventive strategies. National occupational health policies, workplace safety legislation and employee training programs contribute to reducing workplace-related health risks. Built environments such as housing conditions, transportation infrastructure and neighborhood design can either mitigate or exacerbate environmental risks. Poor housing with inadequate ventilation, mold, pests and lack of clean water can lead to respiratory infections and other health problems. Crowded urban areas with little access to green space or recreational facilities can contribute to physical inactivity, obesity and mental health issues. Preventive actions include enforcing housing codes, investing in affordable and safe housing and promoting community design that supports healthy living through walkability, accessibility and social cohesion. Noise pollution is another often-overlooked environmental risk factor. Chronic exposure to excessive noise, especially in urban areas and near transportation hubs, has been linked to sleep disturbances, stress, hearing loss and even cardiovascular issues. Urban planning policies that regulate noise levels create buffer zones around high-noise areas and establish quiet public spaces can help address this issue.
Environmental risk factors are among the most significant and preventable contributors to global disease burden. Through strategic, evidence-based public health measures, it is possible to mitigate these risks and promote healthier environments for all populations. From clean air and water to climate adaptation and urban planning, preventive actions must be proactive, inclusive and sustainable.
Addressing environmental determinants of health requires coordinated efforts at the local, national and global levels. It also demands a commitment to equity, ensuring that all communities regardless of socioeconomic status can live in safe and health-promoting environments. As we confront complex environmental challenges in the 21st century, the integration of environmental health into public health planning will be key to protecting current and future generations.
