    This is a list of minerals which have Wikipedia articles. Minerals are distinguished by various chemical and physical properties. ... Gemstone Toxicity Table

  3. Metal toxicity - Wikipedia

    en.wikipedia.org/wiki/Metal_toxicity

    Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. [ 1 ]

  4. Toxic heavy metal - Wikipedia

    en.wikipedia.org/wiki/Toxic_heavy_metal

    A toxic heavy metal is a common but misleading term for a metal-like element noted for its potential toxicity. [4] Not all heavy metals are toxic and some toxic metals are not heavy. [ 5 ] Elements often discussed as toxic include cadmium , mercury and lead , [ 6 ] all of which appear in the World Health Organization 's list of 10 chemicals of ...

  5. Mineral (nutrient) - Wikipedia

    en.wikipedia.org/wiki/Mineral_(nutrient)

    Finally, although mineral and elements are in many ways synonymous, minerals are only bioavailable to the extent that they can be absorbed. To be absorbed, minerals either must be soluble or readily extractable by the consuming organism. For example, molybdenum is an essential mineral, but metallic molybdenum has no nutritional benefit.

  6. Nickel - Wikipedia

    en.wikipedia.org/wiki/Nickel

    Nickel carbonyl [Ni(CO) 4] is an extremely toxic gas. The toxicity of metal carbonyls is a function of both the toxicity of the metal and the off-gassing of carbon monoxide from the carbonyl functional groups; nickel carbonyl is also explosive in air. [143] [144] Sensitized persons may show a skin contact allergy to nickel known as a contact ...

  7. Palladium - Wikipedia

    en.wikipedia.org/wiki/Palladium

    Palladium is a metal with low toxicity as conventionally measured (e.g. LD 50). Recent research on the mechanism of palladium toxicity suggests high toxicity if measured on a longer timeframe and at the cellular level in the liver and kidney. [ 75 ]

  8. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Visual symptoms distinctive enough to be useful in identifying a deficiency are rare. Most deficiencies are multiple and moderate. However, while a deficiency is seldom that of a single nutrient, nitrogen is commonly the nutrient in shortest supply. Chlorosis of foliage is not always due to mineral nutrient deficiency. Solarization can produce ...

  9. Chromium toxicity - Wikipedia

    en.wikipedia.org/wiki/Chromium_toxicity

    Chromium toxicity refers to any poisonous toxic effect in an organism or cell that results from exposure to specific forms of chromium—especially hexavalent chromium. [1] Hexavalent chromium and its compounds are toxic when inhaled or ingested. Trivalent chromium is a trace mineral that is essential to human
