Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. Chemicals in the water also have negative effects on our health. Pesticides – can damage the nervous system and cause cancer because of the carbonates and organophosphates that they contain.

On human health To put it bluntly: Water pollution kills. ... 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.

If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer.

Health Effects of Environmental Degradation Some urban environmental problems include inadequate water and sanitation, lack of rubbish disposal, and industrial pollution. Unfortunately, reducing the problems and ameliorating their effects on the urban population are expensive.

The effects of air pollution are alarming. It causes global warming, acid rains, respiratory and heart problems, and eutrophication. ... This type of contamination influence health of humans, affects the growth of plants, decreases soil fertility, and changes the soil structure.

The lack of care on surface water affects all oceans, rivers, and lakes directly, where pollution like agricultural chemicals affect ground water, which eventually makes it to the sea. Causes of pollution include oil (35% from city runoff), agriculture pesticides and fertilizer runoff, garbage misplacement, and mining.

Increased runoff reduces groundwater recharge, thus lowering the water table and making droughts worse, especially for agricultural farmers and others who depend on the water wells. When anthropogenic contaminants are dissolved or suspended in runoff, the human impact is expanded to create water pollution.

Some 80 percent of the world's wastewater is dumped—largely untreated—back into the environment, polluting rivers, lakes, and oceans. This widespread problem of water pollution is jeopardizing our health. Unsafe water kills more people each year than war and all other forms of violence combined.

Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil and therefore ...

Microbial pollutants from sewage often result in infectious diseases that infect aquatic life and terrestrial life through drinking water. Microbial water pollution is a major problem in the developing world, with diseases such as cholera and typhoid fever being the primary cause of infant mortality.

Health risk associated with polluted water includes different diseases such as respiratory disease, cancer, diarrheal disease, neurological disorder and cardiovascular disease [21]. Nitrogenous chemicals are responsible for cancer and blue baby syndrome [22].

Water and health. Contaminated water and poor sanitation are linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid, and polio. Absent, inadequate, or inappropriately managed water and sanitation services expose individuals to preventable health risks.

Water pollution harms fish populations in various ways. When nutrients wash into waterways through storm runoff, they deplete oxygen in the water that fish need to survive. ... Heavy metals created when fossil fuels are burned enter the atmosphere, eventually making their way into bodies of water.

Human activities can contribute excess amounts of nitrogen and phosphorus into water. Therefore, human causes of eutrophication include the use of agricultural fertilizers. Other causes include sewage and aquaculture, which is the growing or farming of fish, shellfish and aquatic plants.

Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. ... They may use the same polluted river water for drinking or bathing or irrigation.

Clean drinking water, hygiene, and sanitation play an important part in maintaining health. Contaminated water causes many water-borne infections like diarrhoea, and also serves as a carrier for vectors such as mosquitoes spreading epidemics. ... It results in control of enteric diseases, and boosts child health.
