Zeev,

<<<I calculated back the grams/ton (PPM) values from the grams value given (multiplying
each figure by 2200 and dividing by the appropriate weights (900, 452 and 400
respectively) and then translated the oz/ton to gram/ton by multiplying by 31.3 and
there is a standard deviation of between 7% to 13% between these values (the figures
quoted in grams yielding consistently higher concentrations). Any reason for that? Am I
using the wrong conversion factors?>>>>

As was pointed out 1 ton = 2000 lbs. not 2200 for a 10% difference.
