Researchers from the United States have found thousands of
unknown substances in aerosols of electronic cigarettes, as
well as compounds whose presence is not declared by
manufacturers. The article of scientists was published in the
journal Chemical Research in Toxicology. Previous research
on e-smoking tobacco products has focused on the toxic
substances present in "regular" cigarettes. However, researchers
from Johns Hopkins University decided to establish the full
range of chemicals contained in both liquids and aerosols of
e-cigarettes. The scientists used high-resolution liquid
chromatography and mass spectrometry, previously only used
to analyze organic matter in wastewater, food and blood.
The researchers analyzed tobacco-flavored liquids from four
well-known e-cigarette brands: Mi-Salt, Vuse, Juul, and Blu.
More than two thousand compounds were found in them, most
of which are unknown. Of those that the teams were able to
identify, six were potentially dangerous. Three of this number
have never been found in e-cigarettes before. In addition, the
researchers found two industrial chemicals and a pesticide.
The researchers also discovered hydrocarbon-like compounds
associated with the combustion process, which, according to
the manufacturers, does not occur during the vaping process.
