![]() ![]() What Does REACH Stand For? REACH is a European Regulation relating to One of our recent articles provided an introduction to REACH, and here we’ll look in more detail at the obligations the chemical industry has in meeting REACH regulations. The Obligations of the Chemical Industry in Meeting REACH Regulations.The chemicals being combined can be of varying states: liquid or powder, organic or inorganic, etc. Both processes involve combining different chemicals to create a new chemical. What Is The Difference Between Chemical Blending and Chemical Mixing?Ĭhemical blending and chemical mixing are two common and similar chemical processes.We minimise risks by only selling to established businesses, but we still need to provide the appropriate documentation with chemical sales. Selling chemicals is a highly regulated activity and it’s not without its risks. Chemical Sales: Documentation in the Chemical Industry.Nowadays, the main industrial use of phosphorous is as a fertiliser, and it’s also used as a pesticide, additive, and nerve agent. Phosphorus is also found in the human body and makes up 1% of our body weight – phosphates are a component of DNA. Both are so reactive that they are never found as free elements, but phosphorous does occur naturally in minerals as phosphate, which can be found in the earth’s crust. There are two main forms of elemental phosphorus, white phosphorus and red phosphorus. Brand called it phosphorus mirabilis, meaning ‘miraculous bearer of light’. However, a by-product of this grim experiment was a white substance that glowed in the dark and burned with a brilliant light. He believed that these vapours would then condense into gold. Rather disgustingly, Brand left the urine to rot before boiling it into a paste, heating this paste, and passing the heat vapours through water. To do this, he was experimenting with urine by evaporating it to produce salts. At the time, Brand was trying to create the philosopher’s stone, a legendary alchemical substance that was thought to turn metal into gold. Phosphorous (P) was the first chemical element to be discovered after the ancient times by German alchemist Hennig Brand in 1669. Of course, they weren’t recognised as elements as we know them today, but sulphur (S), silver (Ag), tin (Sn), antimony (Sb), gold (Au), carbon (C) mercury (Hg), and lead (Pb) have all been known materials for thousands of years.įor example, we have evidence of the use of copper from as early as 9,000BC when it was used to make beads and ornaments, and gold artefacts and decorations have been dated to before 6,000BC. You can also hear Dr Blackman on this Elemental special edition Most Boring Element podcast.ĭownload a poster of the periodic table here.There are really two answers to the question ‘which chemical element was first discovered?’ because there are a number of elements that we’ve known about since ancient times. But some have better stories than others, and this made us think about which is most boring.” “This process has highlighted the fact that every element, no matter how abundant or obscure, has its own story – the discovery, history, uses and quirks of each are unique. The Most Boring Chemical Element, a tongue-in-cheek waltz through the elements, came out of Dr Blackman’s Radio New Zealand short podcast series Elemental which he produces with science journalist Alison Ballance.Īs part of the International Year of the Periodic Table of Chemical Elements, and the 150 th anniversary of its creation by Dmitri Mendeleev, Dr Blackman has been investigating the 118 known chemical elements through the podcasts. But which element is the most boring?Ī fascinating quest for the ‘not interesting’ by AUT Professor Allan Blackman and University of Auckland’s Dr Rebecca Jelley has been published in the journal Nature Chemistry. Some are spectacularly dangerous while others, such as the indium in touchscreen technology, are running out. Many elements, like the americium found in smoke detectors, make our lives easier. The chemical elements hydrogen and carbon are necessary for life. AUT Professor Allan Blackman's quest for the most boring chemical element has been published in nature chemistry. ![]()
