Cobalt is important for the human organism because vitamin B12 contains cobalt. Like many other metals, cobalt has a shiny grey metallic appearance. It is a heavy metal due to its high density.<\/p>\n<p><!--more--><\/p>\n<h4>How could I come in contact with it?<\/h4>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\" wp-image-21609 alignright\" src=\"https:\/\/materialneutral.info\/wp-content\/uploads\/2023\/11\/Kobalt-Periodensystem_natros-adobestock--300x200.jpg\" alt=\"Kobalt auf Periodensystem der Elemente. Bildquelle: \" width=\"350\" height=\"233\"\/>As cobalt is used in some everyday applications, you may also come into frequent contact with it. Guitar strings and permanent magnets can contain cobalt. Tools that have to withstand particularly high loads also often contain cobalt (as <a href=\"https:\/\/nanopartikel.info\/wissen\/materialien\/wolframcarbid-cobalt\/\" target=\"_blank\" rel=\"noopener\">tungsten carbide-cobalt<\/a>). Cobalt improves the mechanical properties of prostheses, so you can have cobalt in your own body. Deep blue glass objects often contain cobalt as a colour pigment.<\/p>\n<h4>How dangerous is the material for humans and the environment?<\/h4>\n<p>Cobalt is not dangerous to humans or animals in low doses. As it is used in steel, glass or comparable solid materials, it normally remains firmly bound and no large quantities of cobalt or its compounds are released. If larger quantities of cobalt are ingested, this can lead to poisoning. As with <a href=\"https:\/\/nanopartikel.info\/wissen\/materialien\/nickel\/\" target=\"_blank\" rel=\"noopener\">nickel<\/a>, cobalt can also trigger a contact allergy.<\/p>\n<p>In small quantities, cobalt is vital for most living organisms, including humans. It is contained in the vitamin B12 group. A deficiency of this vitamin can lead to changes in the blood count, damage to the central nervous system and other diseases.<\/p>\n<h4>Conclusion<\/h4>\n<p>Cobalt is a good example of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Paracelsus\" target=\"_blank\" rel=\"noopener\">Paracelsus<\/a>&lsquo; still valid saying &ldquo;The <span class=\"glossaryLink\"  aria-describedby=\"tt\"  data-cmtooltip=\"cmtt_d36a28054105689b80e1a46a42023f27\"  data-gt-translate-attributes='[{\"attribute\":\"data-cmtooltip\", \"format\":\"html\"}]' tabindex='0' role='link'>dose<\/span> makes the poison&rdquo;: small amounts are vital, larger amounts can be harmful to health. Under normal living conditions, a high uptake of cobalt is unlikely.<\/p>\n<h6>By th way&#x2026;<\/h6>\n<h6>Vegans should have the vitamin B12 level in their blood checked occasionally, as there is no vitamin B12 in a purely plant-based diet. However, it can be supplemented vegan via freely available preparations.<\/h6>\n<h6><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Cobalt is used in most modern batteries such as the lithium-ion battery or the nickel-metal hydride batteries that have been [&hellip;]<\/p>\n","protected":false},"featured_media":0,"template":"","usage":[],"absorption":[],"exposition":[],"effect":[],"class_list":["post-20734","element","type-element","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
