Mental Health Disorders Following Exposure to Endocrine Disruptor Chemicals
AI summary Read the abstract
This review examines how endocrine-disrupting chemicals (EDCs), particularly phthalates and bisphenols found in plastics, may contribute to major depressive disorder by disrupting the hypothalamic-pituitary-gonadal-adrenal axis. Growing evidence links EDC exposure to chronic inflammation and neuropsychiatric conditions, raising concern about plastics as an environmental driver of rising global depression rates.
There is growing scientific concern regarding how endocrine-disrupting chemicals (EDCs) impact central nervous system (CNS) disorders. Both anecdotal and preclinical studies suggest a link between EDC exposure and major depressive disorder (MDD), potentially leading to neurodegenerative outcomes. EDCs primarily exhibit their biological effects by interacting with hormone receptors. Nonetheless, there is scientific evidence pointing to dysfunction in the hypothalamic-pituitary-gonadal-adrenal axis, which is linked to neuropsychiatric conditions. Additionally, the global incidence of MDD has risen. Various factors like gender, genetic components, age, hormonal balance, and cultural influences may explain differences in MDD prevalence. Recently, environmental pollutants such as industrial chemicals, emollients, plastics, fungicides, and pesticides have emerged as critical factors influencing this disorder. This review delves into the influence of key phthalate and bisphenol compounds on chronic inflammation and MDD.

Environmental Pollution to Blame for Depressive Disorder?
AI summary Read the abstract
This review examines the link between endocrine-disrupting chemicals (EDCs) — many of which leach from plastics — and the development of major depressive disorder. Animal studies show EDC exposure can alter brain chemistry, cause neurodegeneration, and produce depression-like behaviors. The authors call for more research into whether plastic-associated chemicals contribute to rising rates of depression in the general population.
Human Exposure to Endocrine-Disrupting Chemicals: A Review of Sources, Health Effects, and Biomonitoring Strategies
AI summary Read the abstract
Researchers reviewed the sources, health impacts, and biomonitoring strategies for endocrine-disrupting chemicals (EDCs), which interfere with hormonal signaling even at trace concentrations and are increasingly recognized as a global public health concern. The study highlights gaps in biomonitoring and calls for stronger regulatory frameworks to limit human EDC exposure.
Environmental Chemicals and Maternal Depression During and After Pregnancy: a Scoping Review
AI summary Read the abstract
A scoping review of 27 studies found that maternal exposure to NO2, PM10, phthalates, PBDE, and PFAS was most consistently associated with antenatal and postnatal depression, suggesting that reducing environmental chemical exposures could be a primary prevention strategy for maternal mental health. Phthalates and PFAS are chemical additives in plastics, and this finding strengthens the case that microplastic-associated chemical leaching poses measurable risks to human health beyond the particles themselves.
The effects of endocrine disruptors on the female reproductive system
AI summary Read the abstract
This review examined how endocrine-disrupting chemicals (EDCs), including those associated with plastics, affect the female reproductive system by interfering with the hypothalamic-pituitary-ovarian axis. The authors summarize evidence linking EDC exposure to disrupted hormone signaling, impaired fertility, and increased risk of reproductive disorders.
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.
