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.
In many of these applications there is no substitute for nickel without reducing performance or increasing cost. Nickel is essential for healthy plant life. As a result, it is found naturally in most vegetables, fruits and nuts, and in the food products derived from them, for example â chocolate and wine.
