Air pollution is a global health issue with serious public health implications,
particularly for children. Usually respiratory effects of air pollutants are
considered, but this review highlights the importance of non-respiratory health
hazards. In addition to short-term effects, exposure to criteria air pollutants
from early life might be associated with low birth weight, increase in oxidative
stress and endothelial dysfunction, which in turn might have long-term effects
on chronic non-communicable diseases. In view of the emerging epidemic of
chronic disease in low- and middle- income countries, the vicious cycle of rapid
urbanization and increasing levels of air pollution, public health and regulatory
policies for air quality protection should be integrated into the main priorities
of the primary health care system and into the educational curriculum of health
professionals.
