The calculation* by the American Academy of Pediatrics were based on paint film thickness such that an average film weighed 89 mg./cms. But these were probably high lead paints with a specific gravity of ~ 2.5. Our present day paints have a specific gravity of ~ 1.5. Thus a film of equal thickness (~14 mils or 35u) of present day paint would only weigh 3/5 * such as old high lead paints. If films of equal thickness are put down (\4>ich would be more chan equal coverage) we gain another factor of 5/3. So we could raise the quantity of chips eaten per day to 6-1/2 cms/day.
