Water pollution is a serious issue that can have a detrimental impact on human health. It occurs when harmful substances contaminate bodies of water, rendering them unsafe for human use. These contaminants can include toxic waste, petroleum, disease-causing microorganisms, and chemicals such as pesticides and fertilizers. Polluted water can cause a range of health issues, from metabolic disorders to serious diseases such as cholera and typhoid. With finite sources of drinkable water and increasing pollution, it is a growing concern that jeopardizes the health and safety of people worldwide.

What You'll Learn
- Polluted water can contain microplastics, which may cause oxidative stress, inflammatory reactions, and metabolic disorders
- Polluted water can contain disease-causing bacteria and viruses, which can cause cholera, giardia, and typhoid
- Polluted water can contain chemical pollutants, such as pesticides, fertilisers, and heavy metals, which can cause serious health problems
- Polluted water can contain toxic waste, petroleum, and poisonous substances, which can be harmful to humans
- Polluted water can contain sewage, which can promote algae growth and create eutrophic dead zones where aquatic life cannot survive
Polluted water can contain microplastics, which may cause oxidative stress, inflammatory reactions, and metabolic disorders
In addition to microplastics, polluted water can contain a range of other contaminants, including toxic waste, petroleum, and disease-causing microorganisms. These contaminants can have devastating impacts on both human health and the environment. For example, sewage can promote algae growth, leading to eutrophic "dead zones" where aquatic life cannot survive due to a lack of oxygen.
Water pollution is a widespread problem that jeopardises human health. Unsafe water kills more people each year than war and all other forms of violence combined. Contaminated water can harbour bacteria and viruses responsible for various diseases, including cholera, dysentery, typhoid, hepatitis A, and polio. Chemical pollutants, such as pesticides, fertilisers, and heavy metals, can also cause serious health problems if ingested.
Low-income communities are disproportionately affected by water pollution as their homes are often closest to the most polluting industries. Accidental or illegal releases from sewage treatment facilities and runoff from farms and urban areas contribute harmful pathogens to waterways, even in wealthy nations.

Polluted water can contain disease-causing bacteria and viruses, which can cause cholera, giardia, and typhoid
Water pollution occurs when harmful substances, often chemicals or microorganisms, contaminate a body of water. These contaminants can include toxic waste, petroleum, and disease-causing microorganisms. Human activities that generate domestic sewage and toxic waste are a major source of water pollution, as they contaminate water with disease-causing microorganisms and poisonous substances.
Waterborne pathogens, in the form of bacteria and viruses from human and animal waste, are a significant cause of illness from contaminated drinking water. In addition to cholera, giardia, and typhoid, waterborne pathogens can also cause diarrhoea, dysentery, hepatitis A, and polio.
Chemical pollutants, such as pesticides, fertilisers, and heavy metals, can also cause serious health problems if ingested. Microplastics, which are ingested through drinking water or contaminated seafood, may cause oxidative stress, inflammatory reactions, and metabolic disorders in humans. However, further research is needed to confirm these effects.

Polluted water can contain chemical pollutants, such as pesticides, fertilisers, and heavy metals, which can cause serious health problems
Water pollution occurs when harmful substances, often chemicals or microorganisms, contaminate a body of water, degrading water quality and rendering it toxic to humans. This widespread problem jeopardises our health, with unsafe water killing more people each year than war and all other forms of violence combined.
Waterborne pathogens, in the form of disease-causing bacteria and viruses from human and animal waste, are a major cause of illness from contaminated drinking water. Diseases spread by unsafe water include cholera, giardia, and typhoid. Even in wealthy nations, accidental or illegal releases from sewage treatment facilities, as well as runoff from farms and urban areas, contribute harmful pathogens to waterways.
Additionally, a person may ingest microplastics through drinking water or by eating contaminated seafood. Studies show that microplastics may cause oxidative stress, inflammatory reactions, and metabolic disorders in humans, although further research is needed to confirm these effects.

Water pollution can have a direct impact on human health. For example, a person may ingest microplastics through drinking water or by eating contaminated seafood. Studies show that microplastics may cause oxidative stress, inflammatory reactions, and metabolic disorders in humans. Further, contaminated water can harbour bacteria, such as those responsible for diarrhoea, cholera, dysentery, typhoid, hepatitis A, and polio.

Sewage contains disease-causing microorganisms and poisonous substances. These microorganisms can cause diseases such as cholera, dysentery, typhoid, hepatitis A, and polio. In addition, chemical pollutants, such as pesticides, fertilisers, and heavy metals, can cause serious health problems if ingested.
Unsafe water kills more people each year than war and all other forms of violence combined. In 2015, water pollution caused 1.8 million deaths, according to a study published in *The Lancet*. Contaminated water can also make people ill; unsafe water sickens about 1 billion people annually.
