Investigation of Respiratory Exposure to Flour Dust in Workers Different Bakeries Urmia, Iran, 2021

Asthma is an inflammatory airway disease that affects 22 million Americans in the United States. Research has found associations between impaired respiratory function, including asthma and increased symptoms among asthmatics, and common indoor air pollutants, including tobacco smoke exposure and volatile organic compounds (VOCs). However, findings linking VOC exposure and asthma are inconsisten...

background: silicosis is known in industrial workers for centuries. till recently, the mainstay of its diagnosis and progress was clinical examination of the respiratory system, pulmonary function test and chest radiography. several biomarkers such as serum angiotensin converting enzyme (ace) activity have been examined to determine the extent of silicosis. objective: to elucidate the effect of...

BACKGROUND The exposure to noxious agwents such as lead my cause lung disorders. OBJECTIVES In the present study, pulmonary function tests and self-reported respiratory symptoms in lead exposure workers were compared with matched control subjects. MATERIALS AND METHODS The frequency of respiratory symptoms were evaluated in a sample of 108 lead exposure workers and 100 control subjects with...
