In this article these constraints are applied to baryon Inhomogeneous (IBBN) models. A depletion factor of 3.4 applied to the Li7 constraints will bring Li7, deuterium and He4 constraints in concordance for both the SBBN and IBBN models. A depletion factor of 6.1 will bring concordance for the IBBN model alone.4 pages, 2 figures, to be published in "Frontier in Astroparticle Physics and Cosmology (ResCEU6)"Astrophysicstext
