The Prenatal Exposome: A Salutogenic Framework for Reversing Cumulative Social and Environmental Toxic Loads to Promote Fetal Wholeness
AI summary Read the abstract
This paper proposes a new way of thinking about pregnancy health: instead of just tracking harm from pollution and stress, it argues we should build up protective factors—like clean environments, strong social support, and even time in nature—that help babies thrive despite everyday exposures to things like air pollution, heavy metals, and microplastics. It's a conceptual framework rather than a study with new data, but it makes an important point: combined stress from unequal social conditions and environmental toxins (including microplastics) can compound each other's harm to fetal development, so solutions need to address community and policy-level change, not just individual behavior.

Moving away from traditional reactive, deficit-tracking biomedical paradigms, this work applies a salutogenic lens to maternal-fetal public health. We explore the "triangulation of toxicity"—a compounding loop where structural social inequities (socioeconomic stress, systemic bias) amplify external environmental burdens ($ ext{PM}_{2.5}$, heavy metals, endocrine-disrupting microplastics) to negatively impact early human development via the prenatal exposome.To counteract these systemic loads, this framework organizes public health interventions around five core structural and ecological parameters: nutritional and environmental purity, supportive social ecosystems, intentional empowerment of the maternal-fetal bond, birthing autonomy, and natural neurological buffers (such as the role of forest phytoncides in down-regulating maternal cortisol). By shifting the accountability from individual choices to structural public health policy, this project provides an actionable roadmap for cultivating cross-generational health, equity, and resilience.Keywords: Exposome, Salutogenesis, Fetal Programming, DOHaD, Environmental Justice, Maternal Autonomy, Eco-Medicine, Public Health Policy

The Intrauterine Exposome: A Scoping Review of the Evidence Chain from Maternal Exposure to Foetal Effect and Later-Life Health
AI summary Read the abstract
This review summarizes existing research on how factors during pregnancy, including tobacco smoke, chemicals, air pollution, stress, nutrition and microplastics, may pass from mother to foetus and affect development. It proposes a framework tracing exposure from the mother through the placenta to the foetus, noting that exposure does not always mean the foetus was affected, and identifies gaps for future study.
Placental micro- and nanoplastic contamination: A systematic review of eco-exposome pathways to preterm birth and neonatal outcomes
AI summary Read the abstract
Researchers systematically reviewed 20 studies detecting micro- and nanoplastics in human placental tissue, cord blood, and amniotic fluid, finding higher MNP burdens in preterm versus term placentae and identifying oxidative stress, ferroptosis, impaired trophoblast invasion, and inflammatory signaling as converging molecular pathways linking placental MNP contamination to preterm birth and neonatal morbidity.
Impact of Microplastics on Pregnancy and Fetal Development: A Systematic Review
AI summary Read the abstract
A systematic review of 12 studies confirmed the presence of microplastics ranging from 2.1 to 100 micrometers in human placentas and fetal tissue. Microplastic levels correlated with reduced birthweight, affected gestational age, diminished microbiome diversity, and impaired fetal growth and development, with lifestyle choices influencing placental microplastic burden.
Multi-omics integration reveals human placental molecular signatures associated with microplastics exposure
AI summary Read the abstract
Scientists studied human placenta tissue and found that higher levels of microplastics were linked to changes in genes, proteins, and metabolism, including signs of immune stress, oxidative damage, and problems with mitochondria (the energy-producing parts of cells). This is early evidence that microplastics may disrupt how the placenta functions, which matters because a healthy placenta is essential for delivering nutrients and oxygen to a developing baby. More research is needed to confirm whether these changes actually harm pregnancy outcomes, but the findings raise real questions about how everyday plastic exposure could affect maternal and fetal health
Ignoring the planet: A critical blind spot for research on ageing
AI summary Read the abstract
This paper argues that aging research has overlooked the significant role that environmental factors, including microplastic and nanoplastic exposure, play in shaping lifelong and even intergenerational health outcomes. Researchers highlight that harmful environmental exposures can trigger epigenetic changes during development that program future susceptibility to age-related health decline. The study proposes a new framework connecting aging research with environmental science to address the root causes of declining healthspan.
