After applying the iodine tool for a number of years, in 1983 I  proposed this iodine mechanism.  I published and described this
mechanism in 1986 in the first APGE bulletin. Although I have tested the mechanism continually over the years I have found
nothing that would seriously challenge or contradict the basics of the original theroy. cg

Most of what has been published about iodine in the environment has come from the studies of the
consequence of human iodine deficiency referred to as endemic goiter. Goiter has almost disappeared
with the recognition of the importance of dietary iodine and it's routine addition to table salt. Some iodine
data from goiter studies and subsequent iodine research results are listed below:
Evaporative salts .........................avg.                        10 ppb (Roeber)
Ocean ...................................................                       50 ppb (Rankama, Sahama)
Igneous rocks ...............................avg.                      100 ppb (R. Fuge)
Average Crustal Content ...................                       300 ppb (Manson)
Sedimentary rocks .......................avg.                      1800 ppb (Itkina, Lygalova)
Soils ..............................................avg.                      4800 ppb (Goudge, 350,000 + soil samples)
