[Respiratory allergy and environmental pollution in pediatrics].

Allergic disease and pollution effects on children are a subject of worldwide concern. Outdoor pollution is the sum of acid particle (SO2, NO2, PM) and photochemical (ozone) pollution. Experimental studies demonstrated correlation between animals and humans concerning inhalation of pollutants and inflammatory and functional effects. Several studies among children confirmed with variable odds ratios the interaction between air pollution and respiratory health, but other studies showed no clear effect. Physicians should inform parents with children experiencing respiratory disease.
