Belastung des Dampfes mit Aldehyden bis zu 100 mal geringer als in vorigen Studien angenommen (Mai 2018)

Konstaninos Farsalinos hat eine Studie von Khlystov und Samburova aus dem Jahre 2016 wiederholt, um zu belege, dasss diese Studie mit Messfehlern und unsachgemäßem Gebrauch der E-Zigarette gearbeitet hat. Frei von Aldehyden waren die Messergebnisse nicht. Allerdings ist die normale Raumluft auch immer mit Aldehyden belasten. Hierzu empfehle ich den Beitrag: Formaldehyd – eine gefährliche Zugabe in den Liquids  und Acrolein – wie relevant für das Dampfen? zu lesen und sich auch die Videos von Vanderzarth anzusehen.

Results

Low levels of formaldehyde (8.3–62 μg/g), acetaldehyde (12.1–26.0 μg/g) and acrolein (5.4–19.4 μg/g) were detected, lower by up to 589-fold compared to the previous report. Unflavoured liquid emitted 16.1 μg/g formaldehyde, 5.6 μg/g acetaldehyde and 2.4 μg/g acrolein, significantly lower compared to 2 liquids for formaldehyde and 1 for acrolein. Emissions from the new-generation device were even lower. Aldehyde emissions from all flavoured liquids were 79–99.8% lower than smoking and lower than commonly measured indoor levels and occupational and indoor safety limits.
