Carbonyle im Dampf nur, wenn es kokelt. (11.01.2018)

Farsalinos bespricht in diesem Review Carbonyl Emissions in E-cigarette Aerosol: A Systematic Review and Methodological Considerations aus dem Jahre 2018  sehr ausführlich warum die Belastungen mit Carbonylen (Formaldehyd, etc. sehr, sehr wahrscheinlich. Auf fehlerhaften Anwendungen der E -Zigaretten zurück zu führen ist, sogenannte Kokelstudien.

Conclusion

Carbonyl emissions in e-cigarettes represent an important research topic that has generated a lot of interest. The present review identified different methodologies used in the laboratory assessment of carbonyl emissions. Of particular concern is the large diversity of puffing patterns used, which makes comparisons difficult while in some cases the puffing regime was unrealistic. While varying puffing patterns is understandable considering the diversity of e-cigarette device performance and functional characteristics, it seems that choice of puffing regimes was not based on these parameters. The variability of reported units of carbonyl emissions can also create confusion and may be difficult to interpret. A reasonable recommendation would be to report values per amount of liquid consumption. Additionally, analytical methods need to be accurately validated since the possibility of false positive and false negative results is of concern due to the complexity of ingredients in flavored liquids. Finally, it is particularly important that laboratory studies ensure that no dry puffs are generated under laboratory conditions; otherwise testing realistic conditions relevant to true human exposure cannot be ensured and the findings could be misleading and misinformative for consumers and regulators. A result of these research discrepancies is that the reported carbonyl emissions varied from extremely low (lower not only compared to tobacco cigarette but also compared to environmental levels) to extremely high (up to orders of magnitude higher than tobacco cigarettes. Further research should consider all these concerns in order to improve research quality and find ways to reduce thermal degradation and carbonyl emissions from e-cigarettes.

Fazit 

Ich denke hiermit ist klar, wenn jemand sagt, dass beim Dampfen giftige Chemikalien entstehen, sollte man als Erstes nachfragen, mit welchen Studien das belegt ist. Sehr oft wird denn eine dieser Kokelstudien zitiert werden, welche von Farsalinos in seinem Review angegeben ist. Und dann kann man mit diesem Review das Argument komplett auseinandernehmen. Gerade was Belastungen mit Nitrosaminen und Aldehyde betrifft, sind die sogenannten NRT (Nicotine Replacement Therapy) eindeutig gefährlicher.
