In addition, the work of Kalkbrenner and her colleagues, building on previous studies, showed that women in the third trimester of pregnancy were more susceptible to the damaging effects of air

Existing research has often highlighted the adverse effects of air pollutants
on lung function in school - age
children and adolescents, but the effects of a mother's exposure to
pollution on the lung function of her
unborn child and shortly after birth are less well known.
