A rapid method for the determination of mercury in mainstream cigarette smoke by two-stage amalgamation cold vapor atomic absorption spectrometryPresented at 55th Tobacco Science Research Conference, Greensboro, NC, USA, September 2001.

Mercury content of whole cigarettes, cigars and chewing tobacco packets using pyrolysis atomic absorption spectrometry with gold amalgamation

“…Although this value can be considered an upper limit of the Hg potentially available for human or environmental exposure, transfer of tobacco Hg to mainstream smoke has been estimated at only around 10% [8]. However, this reported percentage seems low given that the Hg content of mainstream smoke was recently found to be 5.0 AE 0.4 ng and 7.4 AE 0.4 ng per cigarette for two different smoking regimes [10]. It should also be noted that whereas cigars contain more Hg, smokers often do not inhale cigar smoke and/or smoke cigars less frequently compared with cigarette smokers.…”

“…These two methods have recently been applied for the determination of Hg in tobacco and mainstream cigarette smoke [9,10]. The former required sample pretreatment and dissolution, whereas the latter a one-of-a-kind specialized apparatus.…”

Levels of heavy metals in the raw and processed Ethiopian tobacco leaves

“…Suzuki et al ( 1976 ) have determined mercury in cigarettes. Chang et al ( 2002 ) reported a rapid method for the determination of mercury in mainstream cigarette smoke by two-stage amalgamation cold vapor atomic absorption spectrometry and the vapor phase mercury in the mainstream smoke was found 7.4 ± 0.4 ng/cigarette. Zhangyu et al ( 2004 ) have reported levels of mercury in tobacco and tobacco additives by microwave digestion and RP-HPLC followed by on-line column enrichment.…”

Direct introduction of cigarette smoke for puff-by-puff trace metals analysis by inductively coupled plasma mass spectrometry

“…For the conventional methods, Hg is primarily present in the gas phase of mainstream cigarette smoke and was determined by two-stage amalgamation cold vapor atomic absorption spectrometry. 42 For Cd, Pb, and As, cigarettes were smoked in accordance with the standard International Organization for Standardization (ISO) smoking method. 43 Cigarette smoke condensate (i.e., particulate phase) was collected by electrostatic precipitation followed by preparation as a slurry sample and analysis by ICP-MS. 44 The detailed analytical procedures and instrument set-up can be found in the cited references.…”
