Phthalates and Incident Diabetes in Midlife Women: The Study of Women’s Health Across the Nation (SWAN)

ContextPhthalates are hypothesized to contribute to diabetes, but longitudinal evidence in humans is limited.ObjectiveWe examined whether phthalate exposure was associated with a higher incidence of diabetes in a racially/ethnically diverse cohort of midlife women.MethodsIn the Study of Women's Health Across the Nation Multipollutant Study, we followed 1308 women without diabetes in 1999-2000 for 6 years. …

Migration of Microplastics and Phthalates from Face Masks to Water

Since the outbreak of COVID-19, face masks have been introduced in the complex strategy of infection prevention and control. Face masks consist of plastic polymers and additives such as phthalates. The aim of this study was to evaluate the migration of microplastics (MP) and phthalates from face masks to water. Four types of masks including …

Mono-(2-ethyl-5-hydroxyhexyl) phthalate promotes uterine leiomyoma cell survival through tryptophan-kynurenine-AHR pathway activation

Uterine leiomyomas (or fibroids) represent the most common tumor affecting up to 80% of reproductive-age women. Epidemiological studies consistently indicate a positive association between exposure to endocrine-disrupting phthalates and leiomyoma risk; however, the underlying mechanisms remain unclear. Here, we demonstrate that the ubiquitous environmental pollutant mono-(2-ethyl-5-hydroxyhexyl) phthalate [MEHHP, the major metabolite of di-(2-ethylhexyl) phthalate] promotes …

Adipogenic Activity of Chemicals Used in Plastic Consumer Products

Bisphenols and phthalates, chemicals frequently used in plastic products, promote obesity in cell and animal models. However, these well-known metabolism-disrupting chemicals (MDCs) represent only a minute fraction of all compounds found in plastics. To gain a comprehensive understanding of plastics as a source of exposure to MDCs, we characterized the chemicals present in 34 everyday …
