Effects of in-utero personal exposure to PM_2.5 sources and components on birthweight.

ABSTRACT: In-utero exposure to fine particulate matter (PM_2.5) and specific sources and components of PM_2.5 have been linked with lower birthweight. However, previous results have been mixed, likely due to heterogeneity in sources impacting PM_2.5 and due to measurement error from using ambient data. Therefore, we investigated the effect of PM_2.5 sources and their high-loading components on birthweight using data from 198 women in the 3rd trimester from the MADRES cohort 48-h personal PM_2.5 exposure monitoring sub-study. The mass contributions of six major sources of personal PM_2.5 exposure were estimated for 198 pregnant women in the 3rd trimester using the EPA Positive Matrix Factorization v5.0 model, along with their 17 high-loading
