Aluminium, the third most common element in the Earth's crust (after oxygen and silicon), serves no function in living cells, but is toxic in large amounts, depending on its physical and chemical forms and magnitude, duration, frequency of exposure, and how it was absorbed by the human body. [38] Transferrins can bind aluminium. [39]
Native aluminium metal is extremely rare and can only be found as a minor phase in low oxygen fugacity environments, such as the interiors of certain volcanoes. [71] Native aluminium has been reported in cold seeps in the northeastern continental slope of the South China Sea.
It can enter the body through inhalation, skin absorption, and ingestion, [5] with the latter of the bunch being the most common. The mucosal cells of the digestive tract contain metallothionein proteins that store the zinc ions. [1] Nearly 90% of zinc is found in the bones, muscles, [5] and vesicles in the brain. [1]
The alkali metals all have the same crystal structure (body-centred cubic) [10] and thus the only relevant factors are the number of atoms that can fit into a certain volume and the mass of one of the atoms, since density is defined as mass per unit volume. The first factor depends on the volume of the atom and thus the atomic radius, which ...
Aluminium poisoning is treated by avoiding aluminium exposure and attempting to remove the element from the body's reserves by chelation. [1] A serum aluminium level of 50-60 mcg/L indicates aluminium overload, may correlate with toxicity, and can be used to initiate chelation therapy in symptomatic individuals.
Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56. How many aluminum cans are in a pound?
Lighter silicates of aluminium are found in the crust, with more magnesium silicate in the mantle, while metallic iron and nickel compose the core. The abundance of elements in specialized environments, such as atmospheres, oceans, or the human body, are primarily a product of chemical interactions with the medium in which they reside.
