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.
Over the years, the vaste expansion of plastic manufacturing has dramatically increased the environmental impact of microplastics [MPs] and nanoplastics [NPs], making them a threat to marine and terrestrial biota because they contain endocrine disrupting chemicals [EDCs] and other harmful compounds. MPs and NPs have deleteriouse impacts on mammalian endocrine components such as hypothalamus, pituitary, thyroid, adrenal, testes, and ovaries. MPs and NPs absorb and act as a transport medium for harmful chemicals such as bisphenols, phthalates, polybrominated diphenyl ether, polychlorinated biphenyl ether, organotin, perfluorinated compounds, dioxins, polycyclic aromatic hydrocarbons, organic contaminants, and heavy metals, which are commonly used as additives in plastic production. As the EDCs are not covalently bonded to plastics, they can easily leach into milk, water, and other liquids affecting the endocrine system of mammals upon exposure. The toxicity induced by MPs and NPs is size-dependent, as smaller particles have better absorption capacity and larger surface area, releasing more EDC and toxic chemicals. Various EDCs contained or carried by MPs and NPs share structural similarities with specific hormone receptors; hence they interfere with normal hormone receptors, altering the hormonal action of the endocrine glands. This review demonstrates size-dependent MPs' bioaccumulation, distribution, and translocation with potential hazards to the endocrine gland. We reviewed that MPs and NPs disrupt hypothalamic-pituitary axes, including the hypothalamic-pituitary-thyroid/adrenal/testicular/ovarian axis leading to oxidative stress, reproductive toxicity, neurotoxicity, cytotoxicity, developmental abnormalities, decreased sperm quality, and immunotoxicity. The direct consequences of MPs and NPs on the thyroid, testis, and ovaries are documented. Still, studies need to be carried out to identify the direct effects of MPs and NPs on the hypothalamus, pituitary, and adrenal glands.

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.
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.
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.
