Toxicological Perspectives on Endocrine-Disrupting Chemicals and Xenobiotic Biotransformation: Mechanistic Insights, Clearance Bottlenecks, and Mitigation Strategies
AI summary Read the abstract
This paper reviews existing research on chemicals like bisphenols, phthalates, PFAS, and microplastics that can disrupt hormone signaling in the body. It describes how the body normally breaks down and clears such chemicals through a three-step internal process, and discusses factors that can make this clearance less effective.
Modern agricultural systems and consumer supply chains heavily depend on synthetic compounds, including plastic packaging, specialized surfactants, and agrochemical formulations. Although acute toxicity risks are closely monitored, chronic low-dose exposure to endocrine-disrupting chemicals (EDCs) poses significant challenges to human and animal physiology. These compounds, such as bisphenols, phthalates, per- and polyfluoroalkyl substances (PFAS), microplastics, and synthetic pesticide residues, can disrupt endogenous hormonal communication through receptor agonism, antagonism, and non-monotonic dose responses. Biological systems counteract these disruptions through a three-phase xenobiotic detoxification network: Cytochrome P450 monooxygenases (Phase I), transferase conjugations (Phase II), and ATP-binding cassette efflux pumps (Phase III). Nonetheless, factors such as carbon-fluorine bond stability, enterohepatic circulation, and mixture effects can hinder effective clearance. This article elucidates the mechanisms of EDCs, examines internal clearance pathways, and identifies actionable mitigation strategies for sustainable food handling and daily living.

The Impact of Endocrine Disruptions on Animal and Human Organism
AI summary Read the abstract
This review examines how endocrine-disrupting chemicals, including bisphenol A, phthalates, and micro- and nanoplastics, interfere with hormonal balance in animals and humans. Researchers describe how these substances interact with hormone receptors, induce epigenetic changes, and disrupt cell signaling pathways affecting reproduction, metabolism, and neurological function. The study highlights that nanoparticles, including microplastics, may amplify endocrine disruption and calls for more research into the molecular pathways involved.
Endocrine disrupting chemicals and their impact on child development: mechanisms, vulnerability windows, and health consequences
AI summary Read the abstract
This review pulls together existing research on "endocrine disruptors", chemicals found in everyday products (including micro- and nanoplastics) that can interfere with hormones, and how they affect children, who are especially vulnerable because their bodies and brains are still rapidly developing. The research suggests these chemicals may disrupt growth, brain development, and puberty, and some effects might even be passed down to future generations, though more studies are still needed to fully confirm this. The takeaway: since these chemicals are nearly impossible to completely avoid, understanding and reducing exposure during pregnancy and childhood could matter for long-term health.
Microplastics as Emerging Contaminants: Investigating their Potential to Alter Human Metabolic and Endocrine Systems
AI summary Read the abstract
This review investigated the potential of microplastics to alter human hormone signaling, synthesizing evidence that plastic particles and their chemical additives can act as endocrine disruptors at environmentally relevant concentrations. The paper highlighted reproductive and metabolic pathways as areas of particular concern.
Chemical behaviour and environmental fate of emerging contaminants: Persistence, transformation, and advanced remediation approaches
AI summary Read the abstract
This review examines the chemical behavior and environmental fate of emerging contaminants including pharmaceuticals, PFAS, microplastics, and engineered nanomaterials. The study highlights that these substances persist in environmental systems at trace concentrations yet can cause significant toxicological effects including endocrine disruption and immunotoxicity, and discusses advanced remediation approaches for addressing these pollutants.
Molecular Mechanisms of Endocrine-Disrupting Chemicals and Emerging-Pollutant Toxicity in Human Reproduction: From Xenobiotic Exposure to Fertility Impairment and Reproductive Carcinogenesis
AI summary Read the abstract
This review pulls together existing research to show that everyday chemicals, including plastics ingredients, pesticides, flame retardants, and even microplastics, seem to disrupt fertility and increase cancer risk through the same underlying biological pathways, like messing with hormones and damaging cell DNA. This matters because it suggests these aren't separate problems but two stages of one process, and it reveals that even "non-persistent" pollutants (like microplastics and personal-care product residues that constantly wash into our environment) can cause lasting harm through repeated low-level exposure, not just chemicals that linger in the body for years.
