Laboratory and epidemiological studies have demonstrated that microplastics can cross the placental barrier, potentially impairing placental function, altering fetal growth, and compromising pregnancy outcomes. Experimental data from animal models and in vitro systems suggest that maternal MP exposure may contribute to adverse neonatal development via multiple mechanisms including oxidative stress, inflammation, endocrine disruption, and epigenetic alterations. These toxicological pathways have been implicated in neurodevelopmental abnormalities, reproductive dysfunction, and immune dysregulation, often in a sex-dependent manner. Despite increasing experimental evidence, major knowledge gaps remain regarding human exposure levels, dose-response relationships, and long-term health implications.

A previous study revealed that 20 μg/mL COE exposure for 120 days could induce malignant transformation of lung epithelial cells. However, the underlying mechanism remains unclear. The epigenetic regulation of long noncoding RNAs (lncRNAs) plays an important role in carcinogenesis. Changes in lncRNA expression during COE-induced malignant transformation were detected, highlighting the importance of gene-environment interactions in cancer. Here, we identified that <i>SFTA1P</i> was downregulated in COE-induced malignant transformation of lung epithelial cells. Interestingly, this reduction was found to have a gradient effect on different stages of cells of COE exposure. Moreover, we found that downregulation of <i>SFTA1P</i> expression in lung cancer was related to patients' poor prognosis. Phenotypic studies have demonstrated that <i>SFTA1P</i> suppressed lung cancer cell proliferation in vitro and in vivo. Further mechanistic studies revealed that <i>SFTA1P</i> directly interacts with ACSS2, an important enzyme responsible for synthesizing acetyl-CoA, leading to abnormal acetyl-CoA metabolism and affecting COE-induced lung carcinogenesis. COE-induced malignant transformed cells or cells with the knockdown of <i>SFTA1P</i> showed significantly increased fatty acid and cholesterol levels, while normal lung epithelial cells or cells with overexpression of <i>SFTA1P</i> showed substantially decreased fatty acid and cholesterol levels.

In this birth cohort study, we quantified the concentrations of 27 metals along with DNA methylation levels at 12 gene regions in cord blood. Neurodevelopment was assessed longitudinally in infancy using the Ages and Stages Questionnaires (ASQ).

Among all metals examined, only lead (mean concentration of 15.3 μg/L) exhibited consistent and statistically significant negative associations with neurodevelopmental performance. A linear dose-response relationship was observed between lead levels and deficits in problem-solving, fine motor, and gross motor skills.
