    en.wikipedia.org/wiki/Lead_poisoning

    Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. [2] Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, and tingling in the hands and feet. [1]

  3. Marsh test - Wikipedia

    en.wikipedia.org/wiki/Marsh_test

    The most common test (and used even today in water test kits) was discovered by Samuel Hahnemann. It would involve combining a sample fluid with hydrogen sulfide (H 2 S) in the presence of hydrochloric acid (HCl). A yellow precipitate, arsenic trisulfide (As 2 S 3) would be formed if arsenic was present. [6]

  4. Simultaneously extracted metals and acid-volatile sulfide

    en.wikipedia.org/wiki/Simultaneously_extracted...

    When dissolved in water, sulfide has a high affinity for numerous heavy metal ions. [5] That is, the solubility-product constants (K sp ) for the sulfides of these metals are very small, meaning they will precipitate as solids when a heavy metal ion and sulfide ion come into contact, as in Equation 2, where M 2+ is a generic metal in the +2 ...

  5. Zinc toxicity - Wikipedia

    en.wikipedia.org/wiki/Zinc_toxicity

    Zinc toxicity is a medical condition involving an overdose on, or toxic overexposure to, zinc. Such toxicity levels have been seen to occur at ingestion of greater than 50 mg of zinc. [1] [unreliable medical source?] Excessive absorption of zinc can suppress copper and iron absorption. The free zinc ion in solution is highly toxic to bacteria ...

  6. Zinc protoporphyrin - Wikipedia

    en.wikipedia.org/wiki/Zinc_protoporphyrin

    Zinc protoporphyrin (ZPP) refers to coordination complexes of zinc and protoporphyrin IX. It is a red-purple solid that is soluble in water. It is a red-purple solid that is soluble in water. The complex and related species are found in red blood cells when heme production is inhibited by lead and/or by lack of iron .

  9. Qualitative inorganic analysis - Wikipedia

    en.wikipedia.org/wiki/Qualitative_inorganic_analysis

    The sodium carbonate test (not to be confused with sodium carbonate extract test) is used to distinguish between some common metal ions, which are precipitated as their respective carbonates. The test can distinguish between copper (Cu), iron (Fe), and calcium (Ca), zinc (Zn) or lead (Pb). Sodium carbonate solution is added to the salt of the ...
