It consists of three categories: health impacts, air quality, and water and sanitation. The health impacts category includes the environmental risk exposure indicator. Environmental health is the branch of public health concerned with all aspects of the natural and built environment affecting human health.
In 2022, the most comprehensive study of pharmaceutical pollution of the world's rivers found that it threatens "environmental and/or human health in more than a quarter of the studied locations". It investigated 1,052 sampling sites along 258 rivers in 104 countries, representing the river pollution of 470 million people.
While both environmental exposures and genetics are known to play important roles in shaping human aging, living conditions and lifestyle choices impact human health much more than genetics ...
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

The effects of microplastics on human health are a growing concern and an actively increasing area of research. Tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
Major forms of pollution include air pollution, water pollution, litter, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, light pollution, and visual pollution. [2] Pollution has widespread consequences on human and environmental health, having systematic impact on social and economic systems.
Water pollution is an environmental issue that affects many water bodies. This photograph shows foam on the New River as it enters the United States from Mexico. Environmental issues are disruptions in the usual function of ecosystems. [1] Further, these issues can be caused by humans (human impact on the environment) [2] or they can be natural ...
