Detrimental consequences of micropolymers associated plasticizers on endocrinal disruption
AI summary Read the abstract
This review details how microplastics, nanoplastics, and plastic-associated plasticizers act as endocrine-disrupting chemicals, interfering with signaling pathways in the pituitary, thyroid, adrenal, and gonadal glands in ways that disrupt hormones, metabolism, fertility, neural development, and fetal growth.
The prevalence of polymer usage in everyday activities has emerged as a detriment to both human life and the environment. A large number of studies describe severe impacts of micropolymers (MP) and nanopolymers (NP) on various organ systems, including the endocrine system. Additionally, plasticizers utilized as additives have been identified as endocrine-disrupting chemicals (EDCs). MP/NP, along with associated plasticizers, affect principal signalling pathways of endocrine glands such as the pituitary, thyroid, adrenal, and gonads, thereby disrupting hormone function and metabolic processes crucial for maintaining homeostasis, fertility, neural development, and fetal growth. This review delves into the sources, distribution, and effects of micropolymers, nanopolymers, and associated plasticizers acting as EDCs. Furthermore, it provides a detailed review of the mechanisms underlying endocrine disruption in relation to different types of MP/NP.

Nano and microplastics: unveiling their profound impact on endocrine health
AI summary Read the abstract
This review summarizes existing research showing that micro- and nanoplastics can disrupt the endocrine (hormone) system, altering reproductive hormones, thyroid function, and gene expression in lab and animal studies. Exposure to these particles triggered inflammation markers and oxidative stress in hormone-producing organs, suggesting that widespread plastic pollution may be contributing to rising rates of hormonal and reproductive health problems.
Microplastics as Emerging Contaminants: Investigating their Potential to Alter Human Metabolic and Endocrine Systems

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.
A review of the endocrine disrupting effects of micro and nano plastic and their associated chemicals in mammals
AI summary Read the abstract
This review summarizes how micro- and nanoplastics carry hormone-disrupting chemicals that can interfere with the thyroid, reproductive organs, and other parts of the endocrine system in mammals. Because these chemicals are not tightly bound to the plastic, they can leach into milk, water, and food, potentially disrupting hormone function in humans who consume them.
Micro- and Nanoplastics as Disruptors of the Endocrine System—A Review of the Threats and Consequences Associated with Plastic Exposure
AI summary Read the abstract
This review summarizes how micro- and nanoplastics carry endocrine-disrupting chemicals that interfere with hormones controlling reproduction, thyroid function, metabolism, and brain development. The reproductive system is especially vulnerable, with studies showing that plastic particle exposure can cause oxidative stress, cell death, and infertility, raising serious concerns given how widespread these particles are in food and the environment.
Implications of plastic-derived endocrine disruptors on human health
AI summary Read the abstract
This review summarizes how chemicals released from plastics, known as endocrine disruptors, can interfere with the body's hormone systems. Common substances like BPA and phthalates mimic or block hormones, contributing to obesity, diabetes, reproductive problems, and developmental issues in children. Micro- and nanoplastics make the problem worse because they can release these hormone-disrupting chemicals inside the body after being ingested or inhaled.
