BACKGROUND
The main objective of this study was to evaluate the concentrations of heavy metals and BTEX (benzene, toluene, ethylbenzene and xylene) in smoke and water bowl of 5-most commonly used tobacco brand in waterpipe in Tehran, the capital of Iran.
METHODS
Five types of conventional tobacco in Tehran were investigated. Heavy metals and BTEX were analyzed in waterpipe smoke, tobacco, charcoal and water bowl prior to and after smoking by using ICP-OES and GC-MS, respectively.
RESULTS
Our results indicated that Khansar and Al Fakher brands had the maximum and minimum concentrations of metals among tobacco consumed, respectively. The results showed that there was a significant difference between content of heavy metals in burned and unburned tobacco. The highest and lowest concentrations of metals were related to Fe and Hg, respectively.
CONCLUSION
Results showed that tobacco, charcoal and smoke of waterpipe contained significant contents of toxic metals and BTEX, and exposure to these components could be the main reason for the concerns about waterpipe smoking.
背景
本研究的主要目的是评估伊朗首都德黑兰最常用的5种水烟烟草品牌的烟雾和水碗中重金属及苯系物（苯、甲苯、乙苯和二甲苯）的浓度。
方法
对德黑兰的5种传统烟草进行了调查。分别使用电感耦合等离子体发射光谱仪（ICP - OES）和气相色谱 - 质谱联用仪（GC - MS）对水烟吸食前后水烟烟雾、烟草、炭火和水碗中的重金属及苯系物进行分析。
结果
我们的结果表明，在吸食的烟草中，Khansar品牌和Al Fakher品牌的金属浓度分别最高和最低。结果显示，燃烧烟草和未燃烧烟草中的重金属含量存在显著差异。金属的最高和最低浓度分别与铁和汞有关。
结论
结果表明，水烟的烟草、炭火和烟雾中含有大量有毒金属和苯系物，接触这些成分可能是人们对水烟吸食感到担忧的主要原因。
