摘要: Objectives To investigate the association between preeclampsia and maternal exposure to ambient particulate matter (PM) with aerodynamic diameter less than 10 μm (PM 10 ) 2.5 μm 2.5 mass sources. Methods Our analysis was based on a hospital cohort of pregnant women (N=3182) residing in Barcelona, Spain, during 2003–2005. Positive matrix factorisation source apportionment (PMF2) used identify sources PM samples obtained by an urban background monitor, resulting detection eight We further combined traffic-related (brake dust, vehicle exhaust secondary nitrate/organics) generate indicator traffic Logistic regression models were developed estimate each separately entire pregnancy trimester one, adjusted for relevant covariates. Results For pregnancy, we found 44% (95% CI 7% 94%) 80% 4% 211%) increase risk associated one IQR brake dust sources, respectively. These findings remained consistent after alternative method (Multilinear Engine (ME2)) used. The results also inconclusive. Conclusions: Risk
