We present predictions of altered primordial abundances around PBHs massive enough to seed SMBHs at 𝑧≈6–7.5. We find that if PBHs with initial masses of ∼105  M⊙ are responsible for such SMBHs, they may produce primordial deuterium and Helium fractions enhanced by ≥10%, and lithium abundance depleted by ≥10%, at distances of up to ≈ a comoving kiloparsec away from the black hole after decoupling. We estimate that ∼108  M⊙ of gas is enhanced (or depleted) by at least one percent. Evidence of these modified primordial deuterium, helium, and lithium abundances could still be present if this circum-PBH gas remains unaccreted by the SMBH and in or near the host galaxies of high-redshift quasars. Measuring the abundance anomalies will be challenging, but could offer a novel way to reveal the primordial origin of such SMBH seeds.","lang":"eng"}],"publication_status":"published","article_processing_charge":"No","scopus_import":"1","month":"11","quality_controlled":"1","doi":"10.1103/physrevd.104.103022","publication":"Physical Review D","year":"2021","publication_identifier":{"issn":["2470-0010","2470-0029"]},"oa":1,"date_updated":"2024-09-19T08:12:35Z","article_number":"103022","citation":{"apa":"Sanderbeck, P.
