Methods A total of 845 children from 4 primary schools and 1653 adults were investigated in Beijing by the questionnaires during a dust event in the spring of 2005.

The association between the concentrations of air pollutants and the incidence of symptoms in exposed population were analyzed by multiple regression models. Results Positive associations were found between the PM_(10) concentrations and respiratory symptoms both in children and adults during the dust event. The children were more susceptible than adults to air pollution. Conclusion The dust events could have adverse effect on human respiratory health.
