Toxicological Effects and Health Impacts of Per- and Polyfluoroalkyl Substances (PFAS) in Humans.
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing mechanistic and health outcome literature without systematic methodology or new human data
PubMed 42198500 · doi:10.3390/toxics14050374
What was done
This was a narrative review synthesizing published literature on the toxicokinetic behaviors, molecular pathways, and multisystem health risks associated with per- and polyfluoroalkyl substances (PFAS) in humans.
What was found
The abstract reports no quantitative values or effect sizes. It qualitatively describes PFAS toxicokinetics as characterized by efficient absorption, strong protein binding, limited metabolism, and slow excretion leading to long biological half-lives and bioaccumulation. Reported adverse health outcomes include endocrine disruption, immune suppression, liver damage, reproductive toxicity, carcinogenic potential, and cardiovascular disease.
Why it matters
The review compiles multisystem toxicological mechanisms to provide a basis for public health prevention strategies, risk assessment, and regulatory decision-making regarding PFAS exposure.
Limits
As a narrative review, it lacks a systematic search methodology, risk of bias assessment, or quantitative pooling of evidence. No specific exposure levels, compound-specific risk estimates, or numbers of reviewed studies are reported in the abstract.
