Natural abundances
Natural abundance of chemical elements by weight of their atoms in ppb (parts per billion; reference value: one billion) in different environments.
Universe
The natural abundance of chemical elements in the universe by weight of their atoms in ppb (parts per billion; reference value: one billion). Real values can deviate strongly from the information given.
Sun

Meteorite
The natural abundance of chemical elements on a carbonaceous meteorite by weight of their atoms in ppb (parts per billion; reference value: one billion). Real values can deviate strongly from the information given.
Earth’s crust
The natural abundance of chemical elements in the Earth’s crust by weight of their atoms in ppb (parts per billion; reference value: one billion). Real values can deviate strongly from the information given.
Oceans
The natural abundance of chemical elements in the oceans by weight of their atoms in ppb (parts per billion; reference value: one billion). Real values can deviate strongly from the information given.
Flowing water
The natural abundance of chemical elements in flowing waters by weight of their atoms in ppb (parts per billion; reference value: one billion). Real values can deviate strongly from the information given.
Human body
The averaged natural abundance of chemical elements in the human body by weight of their atoms in ppb (parts per billion; reference value: one billion). Real values can deviate strongly from the information given.
