safety manager, I’ve identified that workers were exposed to cadmium and lead. Cadmium is a soft malleable transition metal. It is silvery bluish-white in color. Although toxic by nature, this chemical element is commonly used to create dry cell batteries. Like mercury, cadmium has the lowest melting point of groups three through eleven transition metals. Lead is a malleable soft heavy metal that is denser than most common materials. It bluish-white in color when freshly cut, and stains to dull…

Metal poisoning came to the foreground of the American consciousness when a spotlight was shown on the high lead levels in Flint’s water system in Michigan. Although many steps have been performed to reduce lead poisoning, namely in children, such as removing lead paint from homes in 1978, removing lead from gasoline, and proposing stricter laws on imported toys containing lead, heavy metal poisoning still exists. Chelation therapy is still the preferred medical treatment for such heavy metal…

Introduction Transition elements are defined by the IUPAC as atoms that have an incomplete d-subshell, most commonly referring to the d-block.1 When transition metals are not bonded to any other molecule, the d-orbitals are degenerate.2 However, when the metal starts bonding with other ligands, effects on the electrons attached to the metal are induced. Specifically, the d-orbitals split, obtain different energy…

“…And bring back Springsteen, Madonna way before Nirvana there was U2 and Blondie and music still on MTV…” I credit my Dad for influencing the style of music I enjoy listening to. To this day he enjoys reliving his high school and college days listening to songs from his generation. Therefore, the exposure to his music has now made my dad’s style of music my personal favorite.
