How Water Pollution Affects Human Health?

Imagine turning on your tap expecting fresh water, only to find toxic chemicals invisible to the naked eye. Every drop, every bath, and every dish cooked could mean a change in health status. Pollution of water not only poses a threat to the environmental system but also to human life. Its long-term impact ranges from severe fatal diseases to more chronic and permanent health complications. Knowing the causes and effects of water pollution, as well as the threats to human health, is necessary and can be crucial for action before it gets too late.

Reasons for Water Pollution

Water pollution is related to several causes, which include industrial waste and domestic sewage. The causes lead to the degradation of water quality, making water unsafe for drinking and use. Some of the major causes are as follows:

Industrial Wastewater 

Factories and industries dispose of chemicals, heavy metals, and hazardous wastes into the water bodies. These chemicals usually end up in the source of drinking water.

Agricultural Runoff 

Agricultural activities through the use of pesticides, herbicides, and fertilisers are washed into rivers and lakes and contribute to causing pollution in water bodies.

Household Waste 

Bacterial and chemical contamination of water sources results from households' sewerage and improper disposal of their waste.

Oil Spill 

Oil spills from ships and offshore drilling introduce toxic pollutants into oceans and rivers.

Plastic Wastes 

The non-biodegradable plastics choke waterways and release toxic microplastics into water, which thus makes water unfit for drinking.

Understanding these reasons can help in formulating a reduction of contamination and protecting human health.

Effects of Water Pollution on Human Health

The effects of water pollution on human health vary, while on the mild end, they may suffer from minor discomfort to life-threatening disease cases. Contaminated water conveys different pathogens, toxic chemicals, and heavy metals that negatively impact health. Some of the effects include:

Gastrointestinal Diseases 

Waterborne diseases could lead to severe stomach infections with symptoms such as diarrhoea, nausea, vomiting, and dehydration. It can be life-threatening in some situations, especially for children, the elderly, and people with weakened immune systems.

Skin and Eye Irritations

Chemically contaminated water causes rashes, itching, and allergic skin reactions. Contact with polluted water sources through swimming in infected rivers or lakes may also lead to a skin infection and inflamed eyes.

Respiratory Problems 

Polluted water can release harmful fumes and airborne toxins that negatively affect the respiratory system. Inhalation of volatile organic compounds (VOCs) and microbial pathogens can lead to lung infections, asthma, and chronic bronchitis.

Neurological Disorders 

Chronic exposure to heavy metals like lead, arsenic, and mercury causes devastating neurological damage. The toxins stored in the nervous system result in loss of memory, impaired thinking, delayed developmental functions in infants, and more risks of neurodegenerative diseases like Parkinson's and Alzheimer's.

Reproductive Health Issues 

Many chemicals and industrial pollutants, if present in water, can contribute to hormonal imbalances, disorders, and malformation during the pregnancy process. Increased exposure increases risks of sterility, miscarriage, and difficult pregnancies.

Weak Immunity 

Continuous contact with bacteria, parasites, and other toxic chemical exposure weakens one's internal mechanisms of immune resistance, exposing individuals to further diseases, such as infections, autoimmune diseases and chronic illnesses.

Increased Organ Damage Risk  

The accumulation of pollutants, including pesticides, nitrates, and industrial solvents, in the liver and kidneys would cause long-term damage. This might even lead to liver failure, kidney disease, and several fatal diseases.

The water pollution effects on humans are not limited to immediate illnesses. They cause chronic health conditions and a general decline in life expectancy.

Diseases Caused by Water Pollution

The following are water pollution effects on humans: millions of people, the majority of whom reside in developing countries, are diseased because of contaminated water and lack of proper sanitation. Some of the most common diseases include:

• Cholera: A serious bacterial infection that causes acute diarrhoea and dehydration, often resulting in death if not treated.
• Typhoid Fever: Typhoid Fever is a deadly infection due to the Salmonella bacterium, which causes severe fever, weakness, and other intestinal complications.
• Hepatitis A: This is a liver infection due to a virus. The disease symptoms include jaundice, paleness, and digestive disorder.
• Dysentery: This is a bacterial or parasitic disease that presents itself with heavy diarrheal conditions, fever, and abdominal pain.
• Guinea Worm Disease: This is a parasitic disease that causes painful blistering as well as long-term disabilities.
• Arsenicosis: Long-term exposure to arsenic in water causes skin lesions, cancer, and organ failure.
• Fluorosis: Fluorosis is damage to the teeth and bones caused by excessive fluoride in drinking water. These effects lead to deformities and chronic pain.

The World Health Organisation has reported that more than 1 million people die each year from diseases linked to water pollution. The lack of clean drinking water, improved sanitation, and public health policies are some of the barriers to preventing these illnesses.

What Measures Should Be Taken to Prevent Water Pollution?

Water pollution solution requires the collaboration of individuals, commercial ventures, and the government. Some ways with proven success are:

• Improvement in Waste Management: Proper disposal of hazardous materials and reduction of plastic use can significantly reduce water pollution.
• Investment in Treatment Plants: The water treatment plants and facilities for the filtration of wastewater will ensure potable drinking water.
• Governance of Industrial Effluents: Industries should be strictly regulated to limit the amount of toxic waste disposed directly into the water bodies.
• Sustainable Farming Practices: People should reduce the usage of pesticides and fertilisers to prevent harmful runoff into water sources.
• Community Awareness Programmes: People need to educate communities about the importance of clean water and promote responsible use of water.
• Supporting environmental policies: Governments should implement and enforce laws protecting water resources from pollution.

Reasons for water pollution must be addressed through sustainable solutions to protect public health and preserve clean water sources.

What Should Be Done to Avoid Water Pollution?

To avoid water pollution, people, industries, and governments should all join hands together. Some effective measures include the following:

• Proper Waste Disposal: All industrial, household, and medical waste must be disposed of properly, thereby stopping the chemicals that might pollute water sources.
• Decreased Plastic Intake: Lowered intake of plastics and better methods of waste disposal reduce the plastic quantity in water bodies.
• Treatment and Purification of Water: This is an investment in sophisticated filtration and purification systems that ensure that wastewater is treated before it enters the environment.
• Sustainable Agricultural Practices: Organic manures, lesser application of pesticides, and crop rotation techniques can be used to minimise agricultural runoff.
• Strict Industrial Regulation: Regulation for the release of toxic chemicals and heavy metals into water bodies should be applied more strictly to decrease contamination.
• Community Awareness Programmes: The public becomes aware of the significance of clean water and the means of preventing it from getting polluted, which can be put into practice using water responsibly.
• Afforestation and Soil Conservation: The development of trees and natural ecosystems prevents soil erosion and sedimentation in rivers and lakes.

The implementation of these measures is very crucial in reducing the impact of water pollution and ensuring safe drinking water for the next generations.

Conclusion

Water pollution, being one of the worst global issues, with devastating health-related consequences, portrays the seriousness of its effects on humans regarding its prevention and availability of drinking water. Addressing why water pollution needs to be resolved will decrease many diseases related to water pollution as well as create safe drinking water. The protection of water resources depends on both parties: the person and the government.
