Particulate matter comparative size

Prenatal and early life exposures to ambient air pollution and development[1]
"Residential proximity to major roadways, and prenatal exposures to particulate matter <2.5 μm (PM2.5) and ozone (O3) are linked to poor fetal outcomes but their relationship with childhood development is unclear. We investigated whether proximity to major roadways, or prenatal and early-life exposures to PM2.5 and O3 increase the risk of early developmental delays. 4089 singletons and 1016 twins born between 2008 and 2010. Proximity to major roadway was calculated using road network data from the NY Department of Transportation. Concentrations of PM2.5 and O3 estimated by the Environmental Protection Agency Downscaler models were spatiotemporally linked to each child's prenatal and early-life addresses incorporating residential history, and locations of maternal work and day-care. In this prospective cohort study, proximity to major roadway and prenatal/early-life exposures to PM2.5 and O3 were associated with developmental delays. While awaiting larger studies with personal air pollution assessment, efforts to minimize air pollution exposures during critical developmental windows may be warranted."
