Le terme anglais «billion» n'a pas la même signification aux États-Unis : 109 et en Europe : 1012, d'où le risque de confusion. Le ppb américain correspond à une concentration de 1 X 10-9, soit une partie par milliard dans la terminologie française. D'après la norme NF-X20-101 de l'AFNOR, l'emploi de puissances négatives de 10 suivies de l'indication de masse, volume, pression ou mole élimine toute confusion éventuelle. 1, record 1, French, - partie%20par%2010%5Bexposant%209%5D

Selon la source MOUSY (Guide pratique pour le système SI, de M. Moureau), les abréviations «p.p.M.» et «p.p.b.» sont interdites et il convient d'employer 10-9. Il faut souligner, cependant, que l'abréviation «ppb» est tout de même d'emploi très courant en français, en France et au Canada. Selon M. Claude Marchand et Mme Lise Bélair, traducteurs de la section Biologie du Bureau de la traduction à Montréal, l'expression «cinq parties par milliard» doit être abrégée de la façon suivante : 5 p.p. 109 (meilleure solution), ou 5 X 10-9, ou 5/p109, s'il faut absolument éviter l'emploi de «5 ppb». 1, record 1, French, - partie%20par%2010%5Bexposant%209%5D
