Simple process extracts valuable magnesium salt from seawater

Since ancient times, humans have extracted salts, like table salt, from the ocean. While table salt is the easiest to obtain, seawater is a rich source of different minerals, and researchers are exploring which ones they ...

Microalgae purify water and produce valuable compounds

Chemists at Umeå University within the MicroBioRefine consortium show that Nordic microalgae that are allowed to grow in salt water both purify this water efficiently and produce valuable compounds, so-called carotenoids. ...

California and the West broil in record heat wave

A record-setting heat wave made life miserable in much of the West on Tuesday, with California stretching into its second week of excessive heat that taxed the state's power supply with record-setting demand and brought it ...

Researchers reveal how salt may play into climate warming

A team of Skoltech researchers has published a series of three papers dealing with various aspects of how salt from the ocean water and other salts penetrate into frozen soil that contains gas hydrates—icelike crystals ...

Plants can measure the intensity of salt stress

Unfavorable environmental conditions represent considerable stress for plants. A high level of salt content (sodium chloride, NaCl) in the soil is just such a stressor that has a negative impact on plants. Salinization is ...

Salt

Salt is a dietary mineral composed primarily of sodium chloride that is essential for animal life, but toxic to most land plants. Salt flavor is one of the basic tastes, an important preservative and a popular food seasoning.

Salt for human consumption is produced in different forms: unrefined salt (such as sea salt), refined salt (table salt), and iodized salt. It is a crystalline solid, white, pale pink or light gray in color, normally obtained from sea water or rock deposits. Edible rock salts may be slightly grayish in color because of this mineral content.

Chloride and sodium ions, the two major components of salt, are necessary for the survival of all known living creatures, including humans. Salt is involved in regulating the water content (fluid balance) of the body. Salt cravings may be caused by trace mineral deficiencies as well as by a deficiency of sodium chloride itself. Conversely, overconsumption of salt increases the risk of health problems, including high blood pressure.
