Hi Bob,

Tucson lab is currently testing HFCS for mercury.

In general, they found HFCS to be variable, especially in pH.  Low pH, plus
heat, in an iron tank leads to rapid HMF formation, and can cause bee
toxicity.

Further studies have been confounded by the loss of their chemist, and by
problems with greenhouse studies due to lack of a pollen supplement that
will sustain more than two brood cycles.

They are currently looking at the complex sugars in HFCS, but may be limited
by funding.
