Water Pollution 2.4

Biomagnification

the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.

Aquaculture

the rearing of aquatic animals or the cultivation of aquatic plants for food.

Organic Pollutant

are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of their persistence, POPs bioaccumulate with potential adverse impacts on human health and the environment.

Biological Pollutant

can travel through the air and are often invisible. Some common indoor biological pollutants are: animal dander (minute scales from hair, feathers, or skin); dust mite and cockroach parts; infectious agents (bacteria and viruses).

Eutrophication

excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.

irrigation

he supply of water to land or crops to help growth, typically by means of channels.

grey water

is gently used water from your bathroom sinks, showers, tubs, and washing machines. It is not water that has come into contact with feces, either from the toilet or from washing diapers. Grey water may contain traces of dirt, food, grease, hair, and certain household cleaning products.

Saltwater Intrusion

is the movement of saline water into freshwater aquifers, which can lead to contamination of drinking water sources and other consequences. Saltwater intrusion occurs naturally to some degree in most coastal aquifers, owing to the hydraulic connection between groundwater and seawater.

Wetlands

land consisting of marshes or swamps; saturated land.

inorganic Pollutant

one of the easiest ways to tell how the environment is reacting to different types of pollutants. While organic pollution occurs naturally, inorganic pollution is a result of some human interaction or doing (such as fluoride in the water supply which is used to help teeth health).

Point source pollution

pollution is a single identifiable source of air, water, thermal, noise or light pollution. A point source has negligible extent, distinguishing it from other pollution source geometries. ... Water pollution from an oil refinery wastewater discharge outlet.

Non point Soures Pollution

pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground.

Hydro-thermal Pollution

a rise in the temperature of rivers or lakes that is injurious to water-dwelling life and is caused by the disposal of heated industrial waste water or water from the cooling towers of nuclear power plants. thermal pollution in Culture.
