Sulphur

Sulphur is a non-metal that is abundant, tasteless, and odourless. Sulphur is a yellow crystalline solid in its natural state. It can be found as a pure element or as sulphide and sulphate minerals in nature. Although sulphur is known for its foul stench, which is sometimes compared to rotten eggs, that odour is really caused by hydrogen sulphide (H2S).

Sulphur has a complicated crystallography. Sulphur allotropes can take on a variety of crystal forms depending on the environment.

Sulphur is the ninth most abundant element in the universe, accounting for just one out of every 20,000–30,000. Sulphur is found in uncombined form as well as in combination with other elements in widely scattered rocks and minerals, despite being categorised as a small component of the earth’s crust, with a percentage of 0.03 to 0.06 percent. It has been proposed that deeper layers of Earth have a substantially bigger amount of sulphur based on the discovery that certain meteorites contain roughly 12% sulphur. Sulphur in the form of sulphate is found in around 0.09 percent of seawater. The sulphur in subterranean deposits of highly pure sulphur found in domelike geologic formations is thought to have been created by bacteria acting on the mineral-chemical complex anhydrite, which contains sulphur, oxygen, and calcium. Sulphur deposits in volcanic areas are thought to have started from gaseous hydrogen sulphide produced under the Earth’s surface and turned into sulphur by interaction with oxygen in the air.

Chemical and physical characteristics:

Sulphur is a colourless, odourless, and tasteless substance. It is a reactive element that can mix with all other elements except gases, gold, and platinum under the right conditions. Sulphur may be found in a variety of allotropic forms, including rhombic, monoclinic, polymeric, and others. Bright, orthorhombic alpha-sulphur with puckered S8 rings is the most prevalent type. Solubility, specific gravity, crystalline, crystalline organisation, and other physical parameters vary by allotropic form. Depending on temperature and pressure, these distinct allotropes can also exist in defined amounts in equilibrium.

Applications:

Cobalt is utilised in a variety of alloys (superalloys for gas turbine engine components, corrosion resistant alloys, high-speed steels, cemented carbides), magnets and magnetic recording media, petroleum and chemical industry catalysts, and paint and ink drying agents. Cobalt blue is a popular colour among artists, and it may be seen in porcelain, pottery, stained glass, tiles, and enamel jewellery. Cobalt-60, a radioactive isotope, is utilised in medical treatment as well as to irradiate food to preserve it and safeguard consumers.

Sulphur is an easy element to locate on the earth, and even easier to find on the periodic table. It’s at the sixteenth position, right below oxygen (O). Sulphur is a yellowish colour when discovered naturally, and it is commonly found as crystal. At room temperature, sulphur is non-reactive.

Sulphur plays an important role in the body and is required for the creation of a number of important proteins. Sulphur, for example, is required for the production of glutathione, a powerful antioxidant that protects your cells from harm.

 While sulphur found in diet is beneficial to the body, there is little evidence that taking sulphur supplements is beneficial.

Sulphur is an FDA-approved substance for use in over-the-counter dandruff treatments. It is frequently used in conjunction with salicylic acid. However, there is just a smattering of evidence to back up that claim.

Sulphur supplements are frequently used to treat osteoarthritis. MSM may help those with osteoarthritis in their knees.

 It’s conceivable that sulphur can be administered topically without causing harm. Sulphur-containing products at concentrations up to 10% have been used successfully in clinical tests lasting up to eight weeks.

Sulphur’s health impacts :

Sulphur is required by all living organisms. It’s especially vital for humans since it’s a component of the amino acid methionine, which is a must-have in our diet. Sulphur is also found in the amino acid cysteine. Sulphur intake for the average human is roughly 900 mg per day, mostly in the form of protein.

Many simple sulphur derivatives, such as sulphur dioxide (SO2) and hydrogen sulphide, are poisonous, whereas elemental sulphur is not.

Sulphur is typically found in nature as sulphides. Several activities release sulphur bonds into the environment, which are harmful to both animals and humans. These harmful sulphur bonds are also formed in nature by a variety of processes, most commonly when compounds that are not usually present are introduced. They are unwelcomed due to their foul odours and are frequently poisonous.

Sulphuric chemicals’ consequences on human health on a global scale:

•  Neurological consequences and alterations in behaviour
•  Disturbance of blood circulation
•  Damage to the heart
•  Effects  on the eyes and vision
•  Inability to reproduce
•  Immune system impairment
•  Irritable bowel syndrome and other gastrointestinal    problems
•  Damage to the liver and kidneys
•  Defects in hearing

Environmental effects of sulphur:

Sulphur absorption via inhalation of sulphur in the gaseous phase can cause irritation of the eyes and throat in animals. Due to the limited ways of destroying the sulphur bonds that are applied, sulphur is commonly used in industry and discharged into the air.

The detrimental effects of sulphur in animals are largely brain damage, through dysfunction of the hypothalamus, and damage to the nervous system.

Laboratory investigations with test animals have suggested that sulphur can cause substantial vascular damage in veins of the brains, the heart and the kidneys.

Sulphur Dioxide (SO2):

Sulphur dioxide (SO2) is a hazardous inorganic chemical that is heavy, colourless, and heavy. It is created in large quantities during intermediary processes in the production of dioxide and has a strong, unpleasant odour similar to that of a freshly struck match.

Conclusion :

Sulphur has distinct properties that distinguish it from oxygen, such as a larger atomic size that gives sulphur a lower electronegativity. Sulphur metabolites are consumed by all living creatures and depending on the function are dispersed in the different kingdoms from marine organisms to terrestrial plants and animals. Humans, for example, are unable to fix inorganic sulphur in biomolecules and must rely

entirely on preformed organic sulphurous compounds to meet their sulphur requirements.
