Witryna5 paź 2024 · Lead Exposure is Toxic in Any Quantity. Lead is one of the few chemicals known with no safe threshold for exposure. Even minute quantities cause harm. There is no known physiological role played by this element. One interesting fact is that the element is toxic to plants, not just animals. Lead(II) sulfide is so insoluble that it is almost nontoxic, but pyrolysis of the material, as in smelting, gives dangerous fumes. Lead sulfide is insoluble and a stable compound in the pH of blood and so is probably one of the less toxic forms of lead. A large safety risk occurs in the synthesis of PbS using lead carboxylates, as they are particularly soluble and can cause negative physiological conditions.
