This study investigated how exposure to particulate matter (PM) during pregnancy affects levels of natriuretic peptides in newborns' cord blood.
The research was conducted in Mexico City with 101 pregnant women, measuring specific natriuretic peptides in 51 newborns' plasma and estimating PM exposure across all three trimesters.
Results showed that higher PM2.5 exposure in the second trimester and PM10 exposure in the third trimester were linked to lower levels of BNP and ANP in newborns, indicating potential health impacts from prenatal PM exposure.
