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.

测定水烟不同成分中的金属和 BTEX:木炭、烟草、烟雾和水。

背景

本研究的主要目的是评估伊朗首都德黑兰水烟中 5 种最常用烟草品牌的烟气和水碗中重金属和 BTEX(苯、甲苯、乙苯和二甲苯)的浓度。

方法

对德黑兰的五种传统烟草进行了调查。分别使用 ICP-OES 和 GC-MS 对吸烟前后的水烟、烟草、木炭和水碗中的重金属和 BTEX 进行了分析。

结果

我们的结果表明,Khansar 和 Al Fakher 品牌分别在消费的烟草中具有最高和最低的金属浓度。结果表明,燃烧后的烟草和未燃烧的烟草中重金属含量存在显着差异。金属的最高和最低浓度分别与 Fe 和 Hg 有关。

结论

结果表明,烟草、木炭和水烟烟气中含有大量有毒金属和苯系物,暴露于这些成分可能是人们对吸食水烟的担忧的主要原因。
