Associations between Fine Particulate Matter Components, Their Sources, and Cognitive Outcomes in Children Ages 9-10 Years Old from the United States.

ABSTRACT:

Background

Emerging literature suggests that fine particulate matter [with aerodynamic diameter ≤2.5μm (PM2.5)] air pollution and its components are linked to various neurodevelopmental outcomes. However, few studies have evaluated how PM2.5 component mixtures from distinct sources relate to cognitive outcomes in children.

Objectives

This cross-sectional study investigated how ambient concentrations of PM2.5 component mixtures relate to neurocognitive performance in 9- to 10-year-old children, as well as explored potential source-specific effects of these associations, across the US.

Methods

Using spatiotemporal hybrid models, annual concentrations of 15 chemical components of PM2.5 were estimated based on the residential address of child participants from the Adolesc
