Abstract

In this study, 350 vehicles in 20 different models were examined in one of Tehran’s Automobile Technical Inspection Centers. The laboratory tests indicate that longtime exposure to benzene has destructive effects on the blood cells, especially the bone-marrow cells. The concentration levels of benzene caused by the emission of gasoline vapors from fuel tanks doors were measured by PhoCheck EX5000 during a 5 to 15-minute interval for each car. The results indicate that the concentration of benzene caused by the emission of gasoline vapors from the fuel tanks door of the domestic cars was 10 times higher than the imported cars. In most of the imported cars, the amount of benzene in the three measured areas was negligible. This is due to the use of new technology and adaptation of strict environmental standards by the manufacturing country.

环境健康分析:评估德黑兰市车辆油箱门中苯的排放水平
在这项研究中,在德黑兰的一个汽车技术检查中心检查了20种不同型号的350辆汽车。实验室测试表明,长期接触苯对血细胞,尤其是骨髓细胞有破坏性影响。每辆车每隔5到15分钟,用PhoCheck EX5000测量油箱门排放的汽油蒸气引起的苯浓度水平。结果表明,国产车油箱门排放的汽油蒸气所引起的苯浓度是进口车的10倍。在大多数进口汽车中,三个测量区域的苯含量可以忽略不计。这是由于制造国采用了新技术并适应了严格的环境标准。
