Boron - 5B: biological information
Boron is probably not required in the diet of humans but it might be a necessary "ultratrace" element. Boron is required by green algae and higher plants.
Levels in humans
- Human abundance by weight: 700 ppb by weight
- Human abundance by atoms: 410 atoms relative to C = 1000000
