Implication

Observational study uncovers shifting plasticizer exposures and indoor dust pathways in preschool children, indicating declining regulated phthalates alongside rising substitutes.

Key Points

To measure levels of phthalates, substitute plasticizers, and bisphenols in preschool dust, identify indoor exposure determinants, and evaluate children's total exposure alongside 15-year temporal trends.
Collected and analyzed indoor dust samples from 100 preschools in Sweden to quantify plasticizer and bisphenol concentrations and assess environmental sources.
Conducted urine biomonitoring in attending children to estimate total chemical intake and compared metabolite profiles against urine samples collected 15 years earlier.
DiNP and DEHP dominated preschool dust at geometric means of 450 μg/g and 266 μg/g, respectively, with PVC flooring and foam mattresses significantly associated with higher DiNP levels.
Estimated intake from dust ingestion remained below health-based reference values, contributing 2% to 27% of children's total exposure to measured phthalates and BPA.
Children exhibited significantly lower urinary levels of BPA and regulated phthalate metabolites compared to peers 15 years prior, but excreted higher concentrations of DiNP metabolites.
