High salt concentrations within drinking water sources can result in many harmful effects on human health. [14] A study on two coastal villages in Bangladesh showed that when freshwater contaminated with high salinity concentrations is consumed, it can result in health issues such as hair loss, skin diseases, gastric problems, diarrhea, and ...
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
Salinity is an ecological factor of considerable importance, influencing the types of organisms that live in a body of water. As well, salinity influences the kinds of plants that will grow either in a water body, or on land fed by a water (or by a groundwater). [19] A plant adapted to saline conditions is called a halophyte.
On the other side, some plants show adaptations to changes in soil salinity, in that the plant's exposure to salt initiates certain mechanisms for cell osmotic regulation and causes changes in this plant's water obtaining and loss behaviors. [1] One of such plants is the model plant Arabidopsis thaliana, a member of the family Brassicaceae.
Factors such as climate, features of landscape, soils, drainage, aspect and the effects of human activities; all impact on the severity and occurrence of dryland salinity. Dryland salinity effects human and natural resources, such as native vegetation and crops, animals, infrastructure, agricultural inputs, biodiversity, aquatic ecosystems and ...
Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it can be damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific ...
where water tables are shallow, the irrigation applications are reduced. As a result, the soil is no longer leached and soil salinity problems develop; stagnant water tables at the soil surface are known to increase the incidence of water-borne diseases like malaria, filariasis, yellow fever, dengue, and schistosomiasis (Bilharzia) in many ...
The degree of salinity in an estuary or delta is an important control upon the type of wetland (fresh, intermediate, or brackish), and the associated animal species. Dams built upstream may reduce spring flooding, and reduce sediment accretion, and may therefore lead to saltwater intrusion in coastal wetlands.
