Introduction: Benzene, Toluene, Ethyl Benzene and Xylene (BTEX) are Volatile Organic Compounds (VOCs) with similar physical and chemical characteristics. BTEX existing in gasoline releases to the air in result of the gasoline evaporation and the staffs are exposure to it in gasoline stations. The main goal of this project is to determine the risk of occupational exposure to BTEX compounds amon...

Introduction and purpose: Air pollution has been recognized as the most important environmental risk factor worldwide. Benzene which is one of the four pollutants attributed to BTEX (Benzene, Toluene, Ethylbenzene, and Xylene) has been proven to be a carcinogenic component. These pollutants can be easily absorbed and taken into the body via inhalation. With this background in mind, the present ...

Introduction & Objective: BTEX compounds (Benzene, Toluene, Ethylbenzene, Xylene iso-mers) are among the most consumed and dangerous volatile organic compounds which can cause adverse health effects in humans. The water pipe smoke contains numerous toxic compounds such as BTEX compounds.The aim of this study was to evaluate the personal exposure to BTEX compounds at traditional restaurants of H...

Background: Exposure to some volatile organic compounds such as benzene, toluene, ethyl benzene and xylene cause adverse effects on organs and nervous system and moreover causes spread of diseases such as cancer , leukemia which would result in increasing  medical expenses. This study is aimed to detect and measure BTEX (benzene, toluene, ethylbenzene and xylene) in air and compare it with reco...

Purpose: Study of benzene effects on kidney structure in mammals (mouse). Materials and Methods: The mice were studied in 3 groups: controls, solvent and treatment, at favorable laboratory conditions. Treatment mice were administered orally of benzene (0.1cc of benzene solution) for 10 days at a dose 1000 mg/kg of body weight. At the end of each period, the kidneys separated and fixed in paraf...
