ABSTRACT

To determine the concentration of benzene series (BTEX) compounds, 33 samples were collected from indoor air of Ghalyan cafés (GHC), cigarette cafés (CC) and smoking-free cafés (SFC) in Bushehr city, Iran, and analyzed using gas-chromatography - flame ionization detector (GC-FID). The results of this study indicated that the mean±SD values of ΣBTEX in GHC, CC and SFC cafés were 19.46 ± 6.07, 11.34 ± 5.21 and 2.26 ± 0.76 mg/m³, respectively. The mean concentration of BTEX in the cafés with fruit-flavored tobacco was significantly higher than those in traditional cafés (p < 0.05). According to path analysis, the number of active waterpipe heads had the maximum impact on the production of pollutants inside the cafés. The results also indicated that the risk of exposure to BTEX in smoking cafés in Bushehr was very high; it can develop serious carcinogenic and noncarcinogenic risks.

摘要

为了确定苯系（BTEX）化合物的浓度，从伊朗布什尔市的Ghalyan咖啡厅（GHC），香烟咖啡厅（CC）和无烟咖啡厅（SFC）的室内空气中采集了33个样品，并使用色谱法-火焰离子检测器（GC-FID）。研究结果表明，GHC，CC和SFC咖啡厅中ΣBTEX的平均值±SD值为19.46±6.07、11.34±5.21和2.26±0.76 mg / m ³， 分别。带有水果味烟草的咖啡厅中BTEX的平均浓度显着高于传统咖啡厅中的浓度（p <0.05）。根据路径分析，活动水管头的数量对网吧内部污染物的产生影响最大。结果还表明，布什尔的吸烟咖啡馆接触BTEX的风险非常高。它会产生严重的致癌和非致癌风险。
