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.
