    The 2015 Gold King Mine waste water spill was an environmental disaster that began at the Gold King Mine near Silverton, Colorado, [2] when Environmental Protection Agency (EPA) personnel, along with workers for Environmental Restoration LLC (a Missouri company under EPA contract to mitigate pollutants from the closed mine), caused the release of toxic waste water into the Animas River watershed.

  4. Copper zinc water filtration - Wikipedia

    en.wikipedia.org/wiki/Copper_zinc_water_filtration

    Copper zinc water filtration. Copper zinc water filtration is a high-purity brass water filtration process that relies on the redox potential of dissolved oxygen in water in the presence of a zinc anode and copper cathode. It uses dissolved impurities within water as constituent substrate, which are reduced to more physiologically inert compounds.

  6. Metal toxicity - Wikipedia

    en.wikipedia.org/wiki/Metal_toxicity

    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] In the case of lead, any measurable amount ...

  7. Diethylzinc - Wikipedia

    en.wikipedia.org/wiki/Diethylzinc

    Diethylzinc (C 2 H 5) 2 Zn, or DEZ, is a highly pyrophoric and reactive organozinc compound consisting of a zinc center bound to two ethyl groups. This colourless liquid is an important reagent in organic chemistry. It is available commercially as a solution in hexanes, heptane, or toluene, or as a pure liquid.

  8. Zinc deficiency - Wikipedia

    en.wikipedia.org/wiki/Zinc_deficiency

    Zinc deficiency is defined either as insufficient zinc to meet the needs of the body, or as a serum zinc level below the normal range. However, since a decrease in the serum concentration is only detectable after long-term or severe depletion, serum zinc is not a reliable biomarker for zinc status. [1] Common symptoms include increased rates of ...
