Question

name the following

an inorganic salt which is rich in particular nutrients ​

Answer 1

Answer:

The inorganic salt forms of divalent lead, the species of direct interest for toxic exposures of nonoccupational human populations, appear to be very poorly absorbed through the skin in humans. Absorption in this context refers to transdermal passage and entry into the bloodstream. Intradermal binding of inorganic lead followed by exfoliation or extended retention would not be uptake in the systemic toxicological sense. Moore et al. (1980) examined 203Pb-labeled lead acetate uptake in eight adult volunteers when contained in cosmetic preparations and applied in dry or wet forms. Absorption rates ranged from undetected to 0.3% based on label applied. These authors calculated that conventional use of such Pb-containing cosmetics would be associated with 0.06% uptake.
