  2. 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 for

  3. Toxic heavy metal - Wikipedia

    en.wikipedia.org/wiki/Toxic_heavy_metal

    Toxicity reduction attempts to oxidise or reduce the toxic heavy metal ions, via chemical or biological means into less toxic or mobile forms. Physical separation involves the removal of the contaminated soil and the separation of the metal contaminants by mechanical means.

  4. Metals in medicine - Wikipedia

    en.wikipedia.org/wiki/Metals_in_medicine

    Fluid and electrolyte balance, in which fluid balance and electrolyte balance are intertwined homeostatically, is necessary to health in all organisms.It includes reference ranges for cation concentrations of biometals, which in reference to human medicine and veterinary medicine principally includes those for blood serum ion concentrations in humans and in livestock and pets.

  5. Fluoride toxicity - Wikipedia

    en.wikipedia.org/wiki/Fluoride_toxicity

    Fluoride toxicity is a condition in which there are elevated levels of the fluoride ion in the body. Although fluoride is safe for dental health at low concentrations, [1] sustained consumption of large amounts of soluble fluoride salts is dangerous.

  6. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    Forming an ionic bond, Li and F become Li + and F − ions. An ion (/ ˈ aɪ. ɒ n,-ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge ...

    One of the biggest cleanup challenges from the Southern California fires is lithium-ion batteries, which can explode after damage or exposure to heat. The batteries are found in electric vehicles ...

  8. Heavy metals - Wikipedia

    en.wikipedia.org/wiki/Heavy_metals

    A different chemistry-based approach advocates replacing the term "heavy metal" with two groups of metals and a gray area. Class A metal ions prefer oxygen donors; class B ions prefer nitrogen or sulfur donors; and borderline or ambivalent ions show either class A or B characteristics, depending on the circumstances. [32]

  9. Hydrogen ion - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_ion

    The concentration of hydrogen ions and pH are inversely proportional; in an aqueous solution, an increased concentration of hydrogen ions yields a low pH, and subsequently, an acidic product. By definition, an acid is an ion or molecule that can donate a proton, and when introduced to a solution it will react with water molecules (H 2 O) to ...
