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.
Malachite green is also used in endospore staining, since it can directly stain endospores within bacterial cells; here a safranin counterstain is often used. Malachite green is a part of Alexander's pollen stain. Malachite green can also be used as a saturable absorber in dye lasers, or as a pH indicator between pH 0.2–1.8. However, this use ...
Health and safety risks occur because consumers are unable to purchase certain seafood products to protect themselves against these risks based on the product label. Escolar has the potential for toxic side effects and Italy and Japan have banned it from sale. [69] [70] However, in the US restaurants have been found marketing escolar as "white ...
Toxicity studies have shown that this chemical can have serious toxic side effects. [22] Malachite green is not actually an antibiotic, but has antibiotic properties. Malachite green is somewhat stable within the environment and, therefore, is detectable in fish that were treated with the chemical at some point even after treatment has ...
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 ]
"Like MG (malachite green), CV (crystal violet) is readily absorbed into fish tissue from water exposure and is reduced metabolically by fish to the leuco moiety, leucocrystal violet (LCV). Several studies by the National Toxicology Program reported the carcinogenic and mutagenic effects of crystal violet in rodents. The leuco form induces ...
"The potential dangers of using at-home LED masks include headaches, eye strain, sleep disturbances, insomnia and mild visual side effects," she explained. "It’s essential to go to a board ...
