Easy to mix with look-alikes
The spelling risk for ppm is neighbouring look-alikes ("PS", "Pr", …), not just typos; it is anabbreviation pronounced [peːpeːˈʔɛm]. Frequency #40,761 among 3,409 “P” headwords. Gloss: "Mengeneinheit/Quotient, die die Konzentration eines Stoffs in einem anderen Stoff angibt; für Englisch parts per million, für Anzahl Teilchen in einer Million Teilchen; 1 ppm = 0,001 ‰ = 0,0001 %; ...".
ppm has no tracked misspelling variants, since its letter sequence doesn't invite the usual edit-distance slips. It also participates in 20 confusable-pair relationships, "PS", "Pr", "PV", and more, since the words sound or look close enough that writers reach for the wrong one mid-sentence.
No borrowing history is documented for this entry, so spelling patterns must be inferred from the word's phoneme-to-grapheme mapping rather than from a documented borrowing chain. The correct German form is ppm, spelled P-P-M.

Recorded use
Wiktionary examplesThese source excerpts show how ppm appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.
„Im Jahr 2001 schätzte der Weltklimarat (IPCC), dass die CO₂-Konzentration in der Atmosphäre vor der industriellen Ära mehrere tausend Jahre lang bei 280 Millionstel (ppm) gelegen hatte. Bis 1999 war sie auf 367 ppm angestiegen, so der IPCC.“
„Die Zunahme der CO₂-Konzentration in der Atmosphäre seit Beginn der industriellen Entwicklung (etwa 1850) von 290 ppm (ppm) auf jetzt etwa 360 ppm ist zum Teil durch Verwendung fossiler Brennstoffe (Kohle, Erdöl, Erdgas) erklärbar.“
