Preterm birth (PTB) is one of the leading causes of neonatal morbidity and mortality, especially in low- and middle-income countries (LMICs). Many environmental risk factors are poorly monitored in these settings, particularly exposure to excessive heat and air pollution. PM2.5 and black carbon—mostly produced by combustion—are suspected of disrupting fetal development, but their actual impact has not been clearly quantified in these vulnerable contexts.
