Το μονοξείδιο του άνθρακα βρέθηκε σε διάφορα φυσικά και τεχνητά περιβάλλοντα. Οι τυπικές συγκεντρώσεις που μετρήθηκαν σε [[Ppm (μονάδα μέτρησης)|μέρη ανά εκατομμύριο]] είναι ως ακολούθως:

The NASA total was 17 ppmv over 100%, and CO<sub>2</sub> was increased here by 15 ppmv. To normalize, N<sub>2</sub> should be reduced by about 25 ppmv and O<sub>2</sub> by about 7 ppmv.</ref>
