Name Location Dependent population Description Sources of pollution Impact Bharalu River: Assam, India: One of the most polluted rivers in the state of Assam. [19] The biochemical oxygen demand of the river is 52 mg/L in compared to the permissible limit set by the National River Conservation Directorate (NRCD) at 3 mg/L. [20]
This equates to around 7% of the population that is drinking contaminated groundwater. Five mg/L is half of the EPA limit of allowed nitrogen in water. [4] There are two primary sources of pollution for nitrogen: agriculture and septic systems. Agriculture can contribute
Water contaminated by the animal urine carrying the bacteria Begins with flu-like symptoms then resolves. The second phase then occurs involving meningitis, liver damage (causes jaundice), and kidney failure: Otitis Externa (swimmer's ear) Caused by a number of bacterial and fungal species. Swimming in water contaminated by the responsible ...
Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water. Meat is obtained through a variety of methods, including organic farming , free-range farming , intensive livestock production , and subsistence agriculture .
Stagnant water can be contaminated with human and animal feces, particularly in deserts or other areas of low rainfall. [2] Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. [3] Stagnant water may be classified into the following basic, although overlapping, types:
A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
Mushroom-shaped cloud and water column from the underwater nuclear explosion of July 25, 1946, which was part of Operation Crossroads November 1951 nuclear test at the Nevada Test Site, from Operation Buster, with a yield of 21 kilotons. It was the first U.S. nuclear field exercise conducted on land; troops shown are 6 mi (9.7 km) from the blast.
This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect. There are many types of pollution-related diseases, including those caused by air pollution, contaminated soil, water pollution and lacking water, sanitation and hygiene (WASH). Air pollution can be reduced.
