Elevated ambient air zinc increases pediatric asthma morbidity
JM Hirshon, M Shardell, S Alles… - Environmental …, 2008 - ehp.niehs.nih.gov
Background Recent studies indicate that the composition of fine particulate matter [PM≤ 2.5
μm in aerodynamic diameter (PM2. 5)] is associated with increased hospitalizations for
cardiovascular and respiratory diseases. The metal composition of PM2. 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 …
