ECHA est more

  • New device can measure toxic lead within minutes

    Rutgers researchers have created a miniature device for measuring trace levels of toxic lead in sediments at the bottom of harbors, rivers and other waterways within minutes - far faster than currently available laboratory-based tests, which take days. The affordable lab-on-a-chip device could also more

  • Lots of lead in the water? Maybe manganese is to blame

    Manganese is not a particularly toxic mineral. In fact, people need a little in their diets to remain healthy. Research at Washington University in St. Louis has shown however, that in conjunction with certain other chemicals, naturally occurring manganese can lead to big changes in the water in lea more

Group 4 Elements

This latest infographic focuses on the Group 4 (Group 14 in IUPAC nomenclature) elements. One extra fact to add for the curious: although tin has the greatest number of stable isotopes, Xenon trumps it comprehensively if unstable isotopes are also included in the count, with well over 30 possible is more

Lead Iodide & ‘Golden Rain’

Kicking off an occasional new series of graphics with today’s post, which’ll be looking at common chemical reactions encountered in schools. Today kicks off with one of my favourite reactions, the ‘Golden Rain’ demonstration, which involves the synthesis and recrystallisation of lead (II) iodide, an more

The Chemistry of Petrol & The Tetraethyl Lead Story

18th May marks the date of birth of Thomas Midgley, who made significant contributions to something many of us make use of on a regular basis: petrol. Midgley was the research assistant to Charles Kettering, and the duo were responsible for the addition of the compound tetraethyl lead to petrol, an more
