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.
Uses of Nickel. 1  Nickel is used in many products some of you may use everyday including electric guitar strings, magnets and rechargeable batteries. 2  The magnetic properties of nickel actually make it very important for use in computer hard drives.
Nickel is a white metal, with a faint tinge of yellow. It is used widely in making alloys, including copper-nickel (75% copper, 25% nickel) which is used in coinage. Nickel is used in the production of the strongly ferromagnetic alloy alnico which is used to make strong permanent magnets. Alnico alloys iron, nickel, cobalt and aluminum. Stainless steel contains 12-18% chromium and usually about 8% nickel. Iron objects can be plated with nickel for corrosion resistance.
