Suspended sulfate levels demonstrated the only consistent relationship with daily aggravation of asthma and cardiopulmonary ,symptoms,. The "best judgment" of the authors was that suspended sulfate exposure as low as 8-10 p,g/m for 24 hours could be a contributory factor-to "significant aggra- vation of pulmonary ,symptoms," (Health, 1974).
