The purpose of the study was to examine if
exposure to outdoor air pollution during
pregnancy is associated with increased risk of
adverse birth outcomes in Polish urban population

• Air pollutants
• Black smoke (BS)
• Sulphur dioxide (SO2)
• Nitrogen dioxide (NO2)

• Birth outcomes
• Low birth weight (lt2500g)
• Prematurity (lt37 weeks)
• Intrauterine growth retardation
• Birth weight

• CONCLUSIONS
• In Polish urban population
• Ambient air pollution was not found a
  significant risk factor of fetal growth
• Air pollution with black smoke was found a
  significant risk factor of premature birth
