Chemical exposure research, explained
9 open-access chemical exposure studies, each with a flashcard deck and a quiz.
- Phthalates, insulin resistance, and race gaps
In NHANES 2001–2008, several urinary phthalates tracked higher glucose and HOMA-IR, with stronger signals in Mexican-Americans than whites.
- Pregnancy PFAS and lead track lower birth weight
In Cincinnati’s HOME Study, PFAS, lead, and organophosphate pesticides associated with lower birth weight; phthalates and BPA did not.
- Douching helps explain MEP disparities
In NHANES 2001–2004, frequent douching associated with 152% higher urinary MEP; Black women douched more and had higher MEP, linking a product-use pathway to exposure disparities.
- Phthalates in Egyptian premenstrual girls
Egyptian girls had much less MBzP than US girls but several-fold more MiBP, especially with plastic food storage.
- Child chemical mixtures and ADHD scores
A childhood phthalate mixture, weighted toward DEHP metabolites, tracked higher ADHD scores, mainly in autistic children.
- Phthalates, thyroid hormones, and adult blood lipids
In 222 Taiwanese adults, urinary phthalate metabolites tracked with thyroid hormones and lipid markers; T4 appeared to sit on the path from DEHP metabolites to HDL-C, but that mediation interval included the null.
- Childhood phthalates linked to teen liver enzymes
In the Ewha Birth and Growth Cohort, higher childhood urinary phthalates—especially later LMW exposure—tracked with higher AST, ALT, and γ-GTP at ages 10–15, with BMI interactions in girls.
- Phthalates track weaker grip in Korean elders
Higher urinary DEHP and MnBP metabolites were inversely associated with handgrip strength in community-dwelling older adults, especially with a high omega-6/omega-3 diet.
- Serum phthalates track adipose redox markers
In 308 Spanish adults, low-molecular-weight phthalates associated with higher GPx and TBARS in fat, while a phthalate mixture index associated with lower GSH and GSSG.
