The worst air quality in the United States has placed a burden on those suffering from vocal function disorders in the Central Valley of California.
Although the Air Resources Board health analysis includes the lungs and sinuses, research on the effects of pollution on the tissues and function of the oropharynx and larynx has been limited.

This study is concerned with collecting the diagnoses and symptom clusters that have been identified from records of vocal dysfunction sufferers located within this environment through a survey of health professionals.
This primary investigator believes that the inclusion of the oropharyngeal, pharyngeal, and laryngeal physiology into the existing rhinitis and bronchial research within the Air Resources Board health reporting should complete respiratory system representation.
By comparing the vocal dysfunction diagnoses and symptoms from the seven counties of the San Joaquin Valley Air Pollution Control District (SJVAPCD) to the geographic monitor sites data the result may be a set of recommendations for the population affected by seasonal sensitivities.
