67The Metal Content of Bees
- Mar 13, 2007
The lab next door to mine has a new portable x-ray gizmo that takes accurate readings of metals from samples. These are usually soil samples, but I gave him a batch of surplus dried bees to see what would happen. Here are the results.
Everything is in p.p.m. A "<" symbol indicates that the metal was below detection level.
Zinc 80.29 +/- 12.26
Iron 27.21 +/- 27.21
Chromium 66.55 +/- 26.39
Scandium 118.61 +/- 61.19
Calcium 2327.3 +/- 313.53
Potassium 19159.42 +/- 859.55
Some ranges for humans
- Bone/p.p.m: 0.001
- Liver/p.p.m: 0.0004-0.0014
- Muscle/p.p.m: n/a
- Bone/p.p.m: 170000
- Liver/p.p.m: 100-360
- Muscle/p.p.m: 140-700
- Bone/p.p.m: 2100
- Liver/p.p.m: 16000
- Muscle/p.p.m: 16000
- Bone/p.p.m: 0.1-033
- Liver/p.p.m: 0.02-3.3
- Muscle/p.p.m: 0.024-0.84
- Bone/p.p.m: 3-380
- Liver/p.p.m: 250-1400
- Muscle/p.p.m: 180
- Bone/p.p.m: 75-170
- Liver/p.p.m: 240
Not sure what to make of the results, but if anyone had bees nesting on contaminated site it would be an interesting comparison. I wonder what is going on with the high scandium levels. This is supposed to be very rare metal.

The Ungrateful Garden
Midas watched the golden crust
That formed over his streaming sores,
Hugged his agues, loved his lust,
But damned to hell the out-of-doors
Where blazing motes of sun impaled
The serried roses, metal-bright.
"Those famous flowers," Midas ailed,
"Have scorched my retina with light."
This gift, he'd though, would gild his joys,
Silt up the waters of his grief;
His lawns a wilderness of noise,
The heavy clang of leaf on leaf.
Within, the golden cup is good
To heft, to sip the yellow mead.
Outside, in summer's rage, the rude
Gold thorn has made his fingers bleed.
"I strolled my halls in golden shift,
As ruddy as a lion's meat.
Then I rushed out to share my gift,
And golden stubble cut my feet."
Dazzled with wounds, he limped away
To climb into his golden bed.
Roses, roses can betray.
"Nature is evil," Midas said.
