Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.

Mycoremediation has proven to be a cheap and effective remediation technology for dyes such as malachite green, nigrosin and basic fuchsin with Aspergillus niger and Phanerochaete chrysosporium [43] and Congo red, a carcinogenic dye recalcitrant to biodegradative processes, [44] direct blue 14 (using Pleurotus).
Both malachite and azurite, as well as synthetic basic copper carbonate have been used as pigments. [10] One example of the use of both azurite and its artificial form blue verditer [ 11 ] is the portrait of the family of Balthasar Gerbier by Peter Paul Rubens . [ 12 ]
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 ]
Pseudomalachite is a phosphate of copper with hydroxyl, named from the Greek for "false" and "malachite", because of its similarity in appearance to the carbonate mineral malachite, Cu 2 (CO 3)(OH) 2. Both are green coloured secondary minerals found in oxidised zones of copper deposits, often associated with each other.
Groups that advocate for military personnel want the Pentagon to fix what they say are poor living conditions on U.S. bases, including mold, mice and bad water.
Zelyonka. Brilliant green has been used to color silk and wool.. It is indicated for disinfection of fresh postoperative and post-traumatic scars, umbilical cord of newborns, abrasions, cuts, and other violations of the integrity of the skin, in the treatment of purulent-inflammatory processes of the skin - hordeolum ("barley"), meibomite, blepharitis, pyoderma, local furunculosis ...
