Element Scarcity, Periodic Table of

The European Chemical Society Periodic Table depicting element scarcity was unveiled and discussed at a EuChemS event in the European Parliament on Tuesday 22nd January 2019.

The event, chaired by MEPs Catherine Stihler and Clare Moody, presented an encompassing overview of what element scarcity means for us: both on a scientific level, but also economically and politically. A presentation from speaker Natalia Tarasova, IUPAC Past President, contextualised EuChemS' work within the celebrations of the International Year of the Periodic Table, whilst M Pilar Gil, from the University of St Andrews, delivered a remarkable and exhilarating talk on how the recently discovered oldest known wallchart of the Periodic Table was uncovered and dated.

An article in The Conversation, by David Cole-Hamilton of the University of St Andrews, uses this periodic table to look at elements that are overexploited in the modern world.

"Red indicates that dissipation will make the elements much less readily available in 100 years or less: helium (He), silver (Ag), tellurium (Te), gallium (Ga), germanium (Ge), strontium (Sr), yttrium (Y), zinc (Zn), indium (In), arsenic (As), hafnium (Hf) and tantalum (Ta).

"Helium is used to cool the magnets in MRI scanners and to dilute oxygen for deep sea diving. Vital rods in nuclear reactors use hafnium. Strontium salts are added to fireworks and flares to produce vivid red colours. Yttrium is a component of camera lenses to make them shock and heat resistant. It is also used in lasers and alloys. Gallium, meanwhile, is used to make very high-quality mirrors, light-emitting diodes and solar cells."
