• Copernicium is calculated to have several properties that differ from its lighter homologues in group 12, zinc, cadmium and mercury; due to relativistic effects, it may give up its 6d electrons instead of its 7s ones, and it may have more similarities to the noble gases such as radon rather than its group 12 homologues.
• In a January 16, 2011, news story featured in the online edition of the Peoria Journal Star, Associated Press reporter Tammy Webber reported that the oxbow lake, surrounded by a Superfund site, is polluted by high levels of metals such as zinc, lead, arsenic, cadmium, and chromium because of the smelting activity that takes place there for the automotive and appliance industries, chiefly by New Jersey Zinc and Mobil Chemical.
• In April 2016, the US Environmental Protection Agency added the Old American Zinc Fairmont City site to the National Priorities List following the Illinois EPA discovering high levels of lead, arsenic, cadmium and zinc in soil samples.

• The nickel–cadmium battery (Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes.
• The mines were reworked in the late 19th century by French and Greek companies, but mainly for lead, manganese and cadmium.
• MTs have the capacity to bind both physiological (such as zinc, copper, selenium) and xenobiotic (such as cadmium, mercury, silver, arsenic, lead) heavy metals through the thiol group of its cysteine residues, which represent nearly 30% of its constituent amino acid residues.
• For his Doctor of Philosophy thesis on "Neutron beam spectrometer studies of boron, cadmium, and the energy distribution from paraffin", written under Dunning's supervision, he built a neutron spectrometer and developed techniques for its use.
• Its list includes—in addition to copper, lead, nickel, and zinc—the following metals: iron and steel (an alloy), aluminium, tin, tungsten, molybdenum, tantalum, cobalt, bismuth, cadmium, titanium, zirconium, antimony, manganese, beryllium, chromium, germanium, vanadium, gallium, hafnium, indium, niobium, rhenium, and thallium, and their alloys.
• Up until the 1960s they could be eaten, but the State of New York currently recommends against attempting to do so on a regular basis, due to bioaccumulation of PCBs and cadmium that were discovered in the crabs in the 1970s.
• Their compositions include chemical elements such as boron, cadmium, silver, hafnium, or indium, that are capable of absorbing many neutrons without themselves decaying.
• As a bulk metal, cadmium is insoluble in water and is not flammable; however, in its powdered form it may burn and release toxic fumes.
• The principal pigments are a family of yellow, orange and red cadmium sulfides and sulfoselenides, as well as compounds with other metals.
• Based on these results, As You Sow filed notices with over 20 companies, including Ghirardelli and Trader Joe's, for failing to provide the legally required warning to consumers that their chocolate products contain cadmium, lead, or both.
• Up until 1948, cadmium was discarded as waste into the Jinzū River due to it being of no industrial value, exacerbating the levels of the element's release into the waterbody.
