The United Nations has declared 2019 the “International Year of the Periodic Table of the Chemical Elements,” to celebrate the 150th anniversary of the first periodic table and recognise the important role chemistry plays today in promoting sustainable development and providing solutions to global challenges.
Dimitri Mendeleev (1834-1907) created his early periodic table in 1869. He took the 63 known elements and arranged them into a table, mainly by their atomic mass. Although he was not the first person to do this, his interpretation involved a leap of ingenuity, in that he put those with similar properties below each other into groups and left gaps for new elements to be slotted in.
This has since formed the basis for scientists to search for or synthesise the missing elements. In the current periodic table of the chemical elements there are now 118 elements, laid out in order of increasing atomic number. There are repeating patterns in the properties of the elements, which give the periodic table its name.
From a Periodic Table of the Chemical Elements to Chemical Management
Of course, modern chemistry has become about much more than the elements on the periodic table with complex formulations used every day in the manufacture of the products we consume. Chemical formulations such as these can be tested and verified through MRSL testing within the Chem-MAP® programme.
Chem-MAP® is the future of chemical management in the leather, textile and synthetic material supply chains and has bespoke systems to support and reward brands, retailers, manufacturers and chemical companies with the development of robust chemical management systems. Audits, testing and training form the foundation of module content as well as best practice guides.

This month, the Chem-MAP® team have produced their final article highlighting MRSL chemicals such as Short Chained Chlorinated Paraffins (SCCPs), Volatile Organic Compounds (VOCs), Halogenated Solvents, Chlorobenzenes and Chlorotoluenes. These MRSL chemicals can be found within the ZDHC MRSL CAS Chemicals list which the Chem-MAP® team can test to through...Published 28th May 2019 Read more
