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.
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.
