Recent studies indicate that the composition of fine particulate matter [PM <or= 2.5 microm in aerodynamic diameter (PM(2.5))] is associated with increased hospitalizations for cardiovascular and respiratory diseases. The metal composition of PM(2.5) influences allergic and/or inflammatory reactions, and ambient zinc contributes to worsening pulmonary function in susceptible adults. However, information is limited concerning associations between ambient air zinc levels and health care utilization for asthma, especially among children.
