The Roles of pH and Ionic Species in Sulfur Dioxide- and Sulfite-Induced Bronchoconstriction

Article 1987 EN

Sulfur dioxide (SO2) and sulfites are well-described causes of bronchoconstriction in persons with asthma that are chemically related and, therefore, may share a common mechanism of action. When either sulfur species dissolves in aqueous solutions, a pH-dependent equilibrium is established predominantly among bisulfite ion (HSO3-), sulfite ion (SO3=), and SO2. In addition, hydrogen ions may be rel…
