we used experimental animal data to derive a human acute reference dose of 1.33 g/ kg body weight, which corresponds to maximum concentration of TTX in shellï¬sh of 200 g/kg.
Where & Why Nickel is Used. Nickel-containing materials play a major role in our everyday lives â food preparation equipment, mobile phones, medical equipment, transport, buildings, power generation â the list is almost endless.
However, even before it was put to use for creating these types of objects, nickel was utilized in the creation of national currency. The five-cent nickel coin in U.S. currency is made of nickel, even though the element only makes up 25 percent of each individual coin. The bulk of the coin's material is actually copper. Nickel is also used to manufacture specific types of industrial equipment. One application of nickel in an industrial environment is the construction of turbine parts. Many of the components of a turbine, including guide nozzles and different stages of rotors are partially composed of nickel.
