There is data at the USDA
http://www.nal.usda.gov/fnic/foodcomp/index.html
that is claimed to be in ug/100g (there is a note at the end that
agrees that this is ppm*100).
Some is available from the US Agricultural Research Service via
http://64.177.90.157/pfpc/html/f-_in_food.html
that is claimed to be in ppm, but has very similar numbers to the USDA.
References to studies are provided by the BC government
http://wlapwww.gov.bc.ca/wat/wq/BCguidelines/fluoride/fluoridetoo-14.html#P1425_142839
with ranges that seem to indicate that it is the USDA study that is
mislabelled as to units, but the ranges are so large that's not
certain.
I'd appreciate pointers to any independent references on the net to
fluoride in food that might help me resolve this problem.
