just make sure you do your own research as well. while i believe the link posted is very helpful, it is a blog entry, not the FDA website.
|Estimates of Pb exposures for all products were below the PTTI levels for the at-risk population groups of children, pregnant and lactating women and adult women. Table 1 lists the PTTI levels and summarizes results for mass fraction and estimated exposure by population group. Median and maximum values were used instead of mean and standard deviation due to the skewed distribution of results toward lower mass fraction and exposure as seen in Figures 1 and 2. Table 2 provides a complete listing of Pb mass fractions and estimated Pb exposure values for the samples.|
