Three polytypes of chrysotile are known. [8] These are very difficult to distinguish in hand specimens, and polarized light microscopy [6] must normally be used. Some older publications refer to chrysotile as a group of minerals—the three polytypes listed below, and sometimes pecoraite as well—but the 2006 recommendations of the International Mineralogical Association prefer to treat it as ...
Amosite and crocidolite are considered the most hazardous asbestos fiber types; [5] however, chrysotile asbestos has also produced tumors in animals and is a recognized cause of asbestosis and malignant mesothelioma in humans, [6] and mesothelioma has been observed in people who were occupationally exposed to chrysotile, family members of the ...
Chocolate is dangerous for dogs because they are unable to break down theobromine and caffeine, both present in chocolate. Darker chocolate and baking chocolate contain a higher amount of theobromine, thus they are more dangerous than milk chocolate or white chocolate. Small amounts of chocolate may cause vomiting or diarrhea, but larger ...

Here are the toxic plants you should keep away from your pup, including houseplants and landscape plants.
There are three important mineral polymorphs of serpentine: antigorite, lizardite and chrysotile. Serpentine minerals are polymorphous , meaning that they have the same chemical formulae , but the atoms are arranged into different structures, or crystal lattices . [ 7 ]
“While this dog population is 30 or more generations removed from the one present during the 1986 disaster, mutations would likely still be detectable if they conferred a survival advantage to ...
Toxic in humans, dogs, and cats alike. Extremely dangerous to dogs (and children) due to its sweet taste. The antifreeze itself is not toxic, but is metabolized via the liver to the toxins glycolate and oxalate, which cause intoxication and vomiting, metabolic acidosis, and finally acute kidney failure leading to seizures and death. By the time ...
