Human health: drinking water pollutants cause cancer and skin disease
Water pollution has a direct impact on human health and is a major research topic in health economics. Water pollution is caused by human activity and its consequences, such as rising global temperatures caused by CO2 emissions, heat the water, reducing its oxygen content. Felling forests can exhaust water resources and generate organic residue which becomes a breeding ground for harmful bacteria. Chemical dumping from these sectors is one of the main causes of eutrophication of water.
7 billion people use drinking water sources with fecal contaminants. Contaminated water can harbor bacteria, such as those responsible for diarrhea, cholera, dysentery, typhoid, hepatitis A, and polio. Chemical pollutants, such as pesticides, fertilizers, and heavy metals, can cause serious health problems if ingested.
Microplastics are another major pollutant that can be ingested through drinking water or by eating contaminated seafood. One 2020 study estimated that humans ingest between 0.1 and 5 grams of microplastics weekly. Studies show that microplastics may cause oxidative stress, inflammatory reactions, and metabolic disorders in humans.
The impact of drinking water pollutants on cancer is complex. Epidemiological studies have shown that drinking water contaminants, such as chlorinated by-products, nitrates, arsenic, and radionuclides, are associated with cancer in humans.
Water pollution can also cause skin disease. Studies show that water pollution and human health are important research topics in health economics, and scholars have conducted in-depth research on the effects of water pollution on human health and disease heterogeneity.

Water quality: industrialisation, agriculture and urban life degrade water
Water pollution is a major issue that has a direct impact on human health. Water quality is facing severe challenges due to the increase in water consumption and human activity. Industrialization, agricultural production, and urban life have resulted in the degradation and pollution of the environment, adversely affecting the water bodies (rivers and oceans) necessary for life.
Rising global temperatures caused by CO2 emissions heat the water, reducing its oxygen content. Felling forests can exhaust water resources and generate organic residue which becomes a breeding ground for harmful bacteria. Chemical dumping from these sectors is one of the main causes of eutrophication of water. The UN says that more than 80% of the world's sewage finds its way into seas and rivers untreated. Much of the plastic pollution in the ocean comes from fishing boats, tankers and cargo shipping.

Governments should strengthen water intervention management and carry out intervention measures to improve water quality and reduce water pollution’s impact on human health.

Eutrophication: chemical dumping from industry causes algal blooms
Water pollution is a major issue that has a negative impact on human health. Water pollution is caused by human activity and its consequences. Rising global temperatures caused by CO2 emissions heat the water, reducing its oxygen content. Felling forests can exhaust water resources and generate organic residue which becomes a breeding ground for harmful bacteria. Chemical dumping from these sectors is one of the main causes of eutrophication of water. The UN says that more than 80% of the world's sewage finds its way into seas and rivers untreated.
Eutrophication is a process where nutrients such as nitrogen and phosphorus are added to a water body in excess. This can be caused by agricultural runoff, sewage, and industrial waste. The excess nutrients can cause algal blooms, which are uncontrolled growths of algae that can block sunlight and deplete oxygen levels in the water. This can lead to the death of fish and other aquatic organisms and create dead zones in the water.
Chemical dumping from industry is a major cause of eutrophication. Industrial waste often contains high levels of nutrients that can accelerate the growth of algae. When this waste is discharged into water bodies, it can lead to excessive algal growth and create harmful conditions for aquatic life.
The impact of eutrophication can be devastating for aquatic ecosystems. Algal blooms can block sunlight and deplete oxygen levels in the water, leading to the death of fish and other aquatic organisms. Dead zones can form in the water, where there is little to no oxygen and no life can exist. This can have a cascading effect on the entire food chain and lead to the collapse of aquatic ecosystems.
To mitigate the effects of eutrophication, it is important to reduce the amount of nutrients entering water bodies. This can be achieved by implementing better waste management practices, reducing agricultural runoff, and improving industrial waste treatment. Educating communities about the impacts of eutrophication and promoting sustainable practices can also help to prevent further damage to aquatic ecosystems.

Microplastics: drinking water and seafood contain microplastics
A 2020 study estimated that humans ingest between 0.1 and 5 grams of microplastics weekly. Microplastics can be found in drinking water and seafood. Studies show that microplastics may cause oxidative stress, inflammatory reactions, and metabolic disorders in humans. However, further research is needed to confirm these effects.

Water pollution can be caused by chemical pollutants, such as pesticides, fertilizers, and heavy metals. These chemicals can cause serious health problems if ingested.
Water pollution can also have a direct impact on human health through drinking water contaminants. Epidemiological studies have shown that drinking water contaminants, such as chlorinated by-products, nitrates, arsenic, and radionuclides, are associated with cancer in humans. Water pollution can also cause diarrhea, skin disease, and other health issues.
Governments should strengthen water intervention management and carry out intervention measures to improve water quality and reduce water pollution's impact on human health. Water is an essential resource for human survival, and water quality is facing severe challenges due to industrialization, agricultural production, and urban life.
