Dear Or. Conard:
fam enclosing 4 fabfe of the complete data thet we have on the
Marshall tstand food samples, These samples were analyzed in
our laboratory and afi Information avaliable to us is reported,
ft Is my personal feeling that these values ere extremely high
tf we are to consider them as being a steady diet. if we had
to estimate the present average level of Stronttum90 in. the
Amertean diet #4 would be below 10 pyc $r99/G Ca. The average
vatue in the Marshatlese samples is of the order of 900 and
this might
tead to a bone confent in children of greater than
100 ppc Sr9°/g Ca.
Naturatty these figures are purely conjec
tural but are based on comparison of the appropriate fevels In
American food and bone, and the food samples mentioned.
We would be happy to analyze further samples ff they are required
to clarify the general picture.
Sincerely,
John H, Harley, Chief
Analytica! Branch
