Effect of respiratory exposure to benzene, toluene, xylene and ethyl benzene on the spirometric indices in two consecutive years among the petroleum products loading workers
Introduction: Benzene, toluene, xylene and ethylbenzene (BTEX) are the most important aromatic compounds in petroleum products. Due to high vapor pressure, BTEX compounds easily change to gas form and mixed with ambient air. Petroleum products loading workers are exposed to these compounds by the in...
