I recall looking at the chemical profiles of commercial formic some many
years back, and concluding that the levels of contaminants in commercial
formic are only slightly different from higher grades and negligible when
considering the following:

1   how tiny an amount of formic is used
2   what a tiny part of the formic contaminants are
3   the long period of time between treatments
4   that it is used in the brood chamber only
5   the amount that is in the surrounding environment
6   that the formic is diluted with water that may contain the
           same minerals,
7   bees may carry similar amounts oif similar elements into the hive
           with water they gather
8   that most of the formic diffuses out of the hive
9   there is no proof that significant residues remain in the hive
10 the fact that bees consume most of the
         honey and pollen in the brood chamber

Of course, others might reach different conclusions, depending on their
assumptions and what they need to believe.
