Sub-acute Exposure to Benzene Accelerates the Aging Process of Red Blood Cells; an In vivo Study

Background: The well-known toxic effects of benzene toxicity are bone marrow depression, reduction in blood cell counts, and induction of leukemia and aplastic anemia. This study was designed to evaluate biomarkers of aging in red blood cells (RBCs). Methods: Mice were exposed to benzene (50, 100, and 200 mg/kg/day) orally for 28 days. A group of benzene-exposed mice were injected intraperiton...

The use of biomonitoring data in exposure and human health risk assessment: benzene case study

Abstract A framework of "Common Criteria" (i.e. a series of questions) has been developed to inform the use and evaluation of biomonitoring data in the context of human exposure and risk assessment. The data-rich chemical benzene was selected for use in a case study to assess whether refinement of the Common Criteria framework was necessary, and to gain additional perspective on approaches fo...

ارزیابی ریسک بهداشتی مواجهه با آلاینده‌های شیمیایی با تأکید بر ریسک ابتلاء به سرطان خون در یک صنعت پتروشیمی

  Background and Aims: workers in petrochemical industries are exposed to various contaminants and are facing to serious hazards, therefore a comprehensive risk assessment program for identification of hazardous chemicals that affect human health and also determination of hazardous tasks and processes is necessary.     Methods : This descriptive cross-sectional study was conducted in three stag...

The effect of respiratory exposure to benzene, toluene, xylene and ethyl benzene on the spirometric indices among the petroleum products loading workers

Abstract Background and Aim: Benzene, toluene, xylene and ethyl benzene (BTEX) are the most important aromatic compounds in petroleum products. BTEX compounds due to their high vapor pressure, easily change to gas form and mixed with ambient air. Petroleum products loading workers are exposed to these compounds by the inhalation of BTEX compounds. The aim of this study was to evaluate the ef...
