A toxicological risk assessment found tampon metals pose negligible systemic risk. But bioavailable there means absorbed into the blood, and the vaginal microbial community on the tampon surface was never assessed.
A full review of Jaeggi et al. (Gut 2015): iron-fortified porridge increased pathogenic E. coli and enterobacteria, cut bifidobacteria, and inflamed the gut in Kenyan infants.
Metals change microbial ecology; microbes change metal chemistry; inflammation changes local metal access. Follow the mechanisms connecting exposure, nutritional immunity, and disease.
How heavy-metal exposure may reshape the gut microbiome and feed gut-first alpha-synuclein pathology in Parkinson's disease - a metallomic-microbiome view.
How gut microbes methylate and demethylate mercury via hgcAB and merB, how mercury reshapes the microbiome, and why this shapes methylmercury neurotoxic risk.
Low-dose arsenic, cadmium, and lead may reshape the gut microbiome, depleting SCFA producers and promoting obesity and metabolic syndrome. Evidence examined.

The metals atlas now covers 70 elements in 62 sourced profiles. Each entry separates microbial mechanisms, community or host evidence, chemical form, and uncertainty. Search accessibility and newsletter input validation have also been improved.
Scientific corrections address a nickel reference-point unit, the limits of tobacco and Parkinson’s evidence, and three bibliography mismatches. See the dated correction notes in the affected essays and reviews, including nickel, Parkinson’s, prenatal tobacco, and the tampon commentary.
