Sandstorms are a main source of long-distance transport of dust, air pollution and cause various health problems. This study aimed to investigate the acute respiratory and general health complaints in subjects exposed to sandstorm at Riyadh, Saudi Arabia. Methodology: The present descriptive study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia during the period March 2011- June 2012.
