what are some negative effects of water pollution?
445057
The main problem caused by water pollution is that it kills organisms that depend on these water bodies. Dead fish, crabs, birds and sea gulls, dolphins, and many other animals often wind up on beaches, killed by pollutants in their habitat (living environment). Pollution disrupts the natural food chain as well.

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].

Thermal pollution decreases water quality through any process which causes changes in ambient water temperature. ... This simple use of heating or cooling water can have large effects to the oxygen levels in a body of water which impacts local ecosystems and the environment.

Effects on environment The resulting water overuse that is related to water scarcity, often located in areas of irrigation agriculture, harms the environment in several ways including increased salinity, nutrient pollution, and the loss of floodplains and wetlands.

Waterborne organisms (Cryptosporidium, Giardia and E. coli) can cause symptoms such as nausea, vomiting and diarrhea. Spring water could also contain chemicals that can cause long-term health effects, such as kidney and liver damage, nervous system disorders and birth defects.

Effects of Air Pollution High levels of air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose, and throat. Air pollution can also cause worsening of existing heart problems, asthma, and other lung complications.

Polluted water in the ground actually washes the essential nutrients plants need out of the soil. ... Without these nutrients, plants become more susceptible to drought, fungal infections and insects. Water pollution also leaves large amounts of aluminum in the soil, which can be harmful to plants.

Health effects of leachates on humans Water could be rain, or contained in the waste itself. The leachate then pollutes the water with these substances, making nearby water sources unusable for consumption. Health effects could be from an acute/short exposure, or long term chronic exposure to leachates from landfills.

Dangers to our Environment There are many different types of water pollution and all have a different adverse effect on the environment. Heavy metals from industrial processes can accumulate in nearby lakes and rivers. These are toxic to marine life such as fish and shellfish, and can affect the rest of the food chain.

Extensive irrigation of polluted water can not only leach down the soil but also has a negative effect on ground water quality [4]. ... When toxins are in the water, the toxins travel from the water the animals drink to humans when the animals' meat is eaten so the pollutants enter the food chain.

Soil Problems Water pollution makes the soil acidic and negatively affects the solubility of nutrient ions, such as iron, magnesium, potassium and calcium ions. As a result, water removes these nutrients more quickly from the soil and sends them into streams and lakes, according to Cornell University in New York.

Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000 diarrhoeal deaths each year. By 2025, half of the world's population will be living in water-stressed areas.

Chemical exposure through drinking water can lead to a variety of short- and long-term health effects. Exposure to high doses of chemicals can lead to skin discoloration or more severe problems such as nervous system or organ damage and developmental or reproductive effects.

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.
