Abstract

Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant of global concern due to its environmental presence,bioaccumulative potential and toxicological impacts. This review synthesizes current knowledge regarding PFOS exposure, bioaccumulation patterns and adverse health outcomes in human population. Analysis of worldwide biomonitoring data, and epidemiological studies reveals PFOS systemic effects, including immunological dysfunction (decreased vaccine response), developmental toxicity (reduced birth weight), hepatic metabolic disruption, potential carcinogenogenicity, and reproductive abnormalities. At the molecular level, PFOS induces toxicity through multiple pathways, including PI3K/AKT/mTOR pathway inhibition, PPARα activation, NF-κB signaling modulation, and oxidative stress induction. Recent advances in analytical methodologies have enhanced our understanding of PFOS distribution and fate, while evolving egulatory frameworks attempts to address its risk. This review identifies critical research gaps and emphasized the need for coordinated multidisciplinary approaches to address this persistent environmental contaminant.

期刊介绍： The Journal of Hazardous Materials serves as a global platform for promoting cutting-edge research in the field of Environmental Science and Engineering. Our publication features a wide range of articles, including full-length research papers, review articles, and perspectives, with the aim of enhancing our understanding of the dangers and risks associated with various materials concerning public health and the environment. It is important to note that the term "environmental contaminants" refers specifically to substances that pose hazardous effects through contamination, while excluding those that do not have such impacts on the environment or human health. Moreover, we emphasize the distinction between wastes and hazardous materials in order to provide further clarity on the scope of the journal. We have a keen interest in exploring specific compounds and microbial agents that have adverse effects on the environment.
