Prenatal ambient air pollutant mixture exposure and neurodevelopment in urban children in the Northeastern United States.

ABSTRACT:

Background

Studies of prenatal air pollution (AP) exposure on child neurodevelopment have mostly focused on a single pollutant. We leveraged daily exposure data and implemented novel data-driven statistical approaches to assess effects of prenatal exposure to a mixture of seven air pollutants on cognitive functioning in school-age children from an urban pregnancy cohort.

Methods

Analyses included 236 children born at ≥37 weeks gestation. Maternal prenatal daily exposure levels for nitrogen dioxide (NO₂), ozone (O₃), and constituents of fine particles [elemental carbon (EC), organic carbon (OC), nitrate (NO₃^-), sulfate (SO₄^2-), ammonium (NH₄⁺)] were estimated based on residential addresses
