Water pollution increases the risk of waterborne diseases
Water pollution is a significant contributor to infant mortality, with one in four infant deaths attributed to unhealthy environments. According to the World Health Organization (WHO), environmental risks such as unsafe water claim the lives of 1.7 million children under the age of five each year. Water pollution increases the risk of waterborne diseases, which is a leading cause of infant mortality.
Waterborne diseases are illnesses caused by pathogenic microorganisms transmitted through contaminated water. These diseases include cholera, dysentery, typhoid fever, and hepatitis A, among others. Contaminated water sources, such as rivers, lakes, or wells, serve as breeding grounds for disease-causing bacteria, viruses, and parasites. When infants consume water from these sources, they ingest harmful microorganisms, leading to severe gastrointestinal infections.
In developing countries, particularly in Sub-Saharan Africa, water pollution poses a grave threat to infant health. Limited access to clean water and sanitation facilities exacerbates the problem. For instance, in Nigeria, approximately 66 million people lack access to improved water sources, and this shortage contributes to a high number of childhood deaths. The risk of mortality from waterborne diseases is significantly elevated for infants in these regions.
Water pollution by industrial effluents and untreated sewage further exacerbates the problem. Toxic chemicals, heavy metals, and other pollutants discharged into water bodies can have detrimental effects on infant health. Exposure to these contaminants, even at low levels, can lead to developmental issues, respiratory problems, and increased susceptibility to diseases.
Furthermore, water pollution can indirectly affect infant mortality by impacting the health of pregnant women. Drinking contaminated water or exposure to polluted environments during pregnancy can increase the risk of premature birth and low birth weight, which are associated with higher infant mortality rates.
To mitigate the impact of water pollution on infant mortality, it is imperative to implement effective water treatment and sanitation measures. This includes investing in water purification technologies, improving wastewater treatment processes, and promoting better waste disposal practices. Additionally, raising awareness about the dangers of water pollution and educating communities about safe water handling practices can help reduce the risk of waterborne diseases.

Water pollution is linked to diarrhoea
Water pollution is a major contributor to infant mortality, with one in four infant deaths attributed to unhealthy environments. According to the World Health Organization (WHO), environmental risks such as unsafe water take the lives of 1.7 million children under the age of five every year. Water pollution is especially detrimental to infants and young children due to their developing organs, immune systems, and smaller bodies.
The impact of water pollution on diarrhoeal diseases is significant. Contaminated water sources expose children to pathogens that cause diarrhoea. This is particularly harmful during the post-neonatal period when children are more mobile and likely to come into contact with contaminants. Additionally, during this period, weaning foods are often prepared using unimproved water, further transmitting pathogens that cause diarrhoea.
The relationship between water pollution and diarrhoea is also influenced by socioeconomic factors. Households in rural areas and low-income households are more likely to have unimproved water sources and sanitation facilities, increasing the risk of waterborne diseases. In Nigeria, for instance, the number of people with access to improved water and sanitation is very low, particularly in rural areas.
Access to improved water and sanitation is crucial for reducing the impact of water pollution on diarrhoeal diseases and infant mortality. Interventions such as providing safe water, improving sanitation, and promoting good hygiene practices can prevent children's deaths and diseases. These interventions are included in the Sustainable Development Goals (SDGs), which aim to end preventable deaths of newborns and children under five by 2030.

Unimproved water sources cause childhood mortality
Unimproved water sources are a leading cause of childhood mortality, with nearly a billion people lacking access to improved drinking water sources globally. This is especially true in Sub-Saharan Africa, where nearly half the population lacks access to clean water, and it is the worst-affected region according to the World Health Organization (WHO).
In Nigeria, for example, approximately 66 million people lack access to clean water. A study examining the impact of water and sanitation on childhood mortality in the country found that the risk of mortality from unimproved water sources was significantly higher, at 38% for post-neonatal mortality and 24% for child mortality.
In India, heavily polluted rivers are known to have a heavy disease burden. Official estimates suggest that 37.7 million Indians are affected by waterborne diseases each year, and 1.5 million children die of diarrhea alone. The Ganga, India's holiest river, is one of the most polluted, with 501 million liters of industrial effluent emptied into it daily.
The impact of unimproved water sources on childhood mortality is significant, and it is crucial to address this issue to prevent preventable child deaths, especially in developing countries.

Water pollution affects the respiratory system
Water pollution has a detrimental impact on the respiratory system, causing a range of health issues and contributing to infant mortality. Here are some key ways in which water pollution affects respiratory health:
Waterborne Diseases: Contaminated water sources, such as polluted rivers or unsafe drinking water, can lead to the spread of waterborne diseases. These diseases can have a direct impact on the respiratory system, causing infections and inflammation. For example, water pollution can lead to the transmission of pathogens that cause diarrheal diseases, which have been associated with respiratory complications.
Indoor Air Pollution: The use of unclean fuels, such as coal or dung for cooking and heating, can result in indoor air pollution. This is particularly relevant in households without proper ventilation. The pollutants released from these fuels can irritate the respiratory tract and increase the risk of respiratory infections, including pneumonia.
Outdoor Air Pollution: Water pollution often contributes to outdoor air pollution as well. Industrial effluents discharged into water bodies can emit harmful pollutants into the air, including particulate matter and toxic chemicals. These pollutants can be inhaled, causing respiratory issues, especially in children whose respiratory systems are still developing.
Asthma and Chronic Respiratory Diseases: Exposure to air pollution, including pollutants from water contamination, has been linked to an increased risk of developing asthma and other chronic respiratory diseases. Water pollution can contribute to poor air quality, triggering asthma symptoms and making the condition more severe in children.
Respiratory Infections in Early Life: Infants and young children are particularly vulnerable to the effects of water pollution on the respiratory system. Exposure to polluted water sources and air pollution can lead to respiratory infections during the early stages of life, increasing the risk of neonatal and infant mortality.
Overall, water pollution has a significant impact on respiratory health, especially in vulnerable populations such as infants and young children. The consequences of water pollution on the respiratory system contribute to the high infant mortality rates observed in areas with unhealthy environments, particularly in regions like Sub-Saharan Africa.

Water pollution impacts the digestive system
Water pollution has a detrimental impact on the digestive system, which can be fatal for infants. Waterborne diseases, such as diarrhoea, are a significant cause of infant mortality, with 1.4 million child deaths globally each year. In Nigeria, for instance, approximately 150,000 children under five years old die from diarrhoea annually. Unsafe water, inadequate sanitation, and poor hygiene practices expose infants to harmful pathogens, which can lead to deadly diarrhoeal diseases.
The digestive system of infants is still developing, making them more susceptible to waterborne diseases. Their immune systems are not fully mature, and they are more vulnerable to infections and diseases caused by contaminated water. Moreover, infants may ingest contaminated water or touch surfaces polluted with harmful pathogens, increasing their risk of contracting waterborne illnesses.
Water pollution can contain various contaminants, including bacteria, viruses, and parasites, which can cause gastrointestinal infections. These pathogens can invade the digestive system, leading to inflammation, fluid loss, and malnutrition. In severe cases, waterborne diseases can cause dehydration, electrolyte imbalances, and even septic shock, which can be life-threatening for infants.
Additionally, water pollution can introduce toxic chemicals into the digestive system, such as heavy metals and pesticides. These toxins can interfere with the normal functioning of the digestive system, leading to nausea, vomiting, abdominal pain, and diarrhoea. In some cases, toxic chemicals can have long-term effects, impacting the development and health of the infant's digestive system.
Furthermore, water pollution can also impact the nutritional quality of food prepared with contaminated water. Contaminants in water can affect the nutritional value of food, reducing the availability of essential nutrients for infants. This can lead to malnutrition, compromising the infant's digestive and overall health.
