Researchers from the Harvard T.H. Chan School of Public Health (Harvard Chan School) examined 75 popular e-cigarette products. They classified the products into four flavor categories—tobacco, menthol, fruit and other—and then screened them for the presence of endotoxin and glucan. Dentist in East Village NY
The discoveries indicated that 17 items contained distinguishable centralizations of endotoxin, while 61 items contained perceivable convergences of glucan. Further examination uncovered that cartridge tests had 3.2 times higher centralizations of glucan than the e-fluid examples. Glucan fixations were likewise essentially higher in tobacco-and menthol-enhanced items, contrasted and natural product seasoned items. In any case, organic product enhanced items were higher in endotoxin focuses, which shows that crude materials utilized in the creation of flavors may be a wellspring of microbial pollution, as indicated by the exploration group.
“Airborne Gram-negative bacterial endotoxin and fungal-derived glucans have been shown to cause acute and chronic respiratory effects in occupational and environmental settings,” said senior author Dr. David Christiani, Elkan Blout Professor of Environmental Genetics at the school. “Finding these toxins in e-cigarette products adds to the growing concerns about the potential for adverse respiratory effects in users.” Previous research from the Harvard Chan School has shown that chemicals linked with severe respiratory disease are found in common e-cigarette flavors.

The specialists noticed that the tainting may happen anytime during the generation of the fixings or of the completed e-cigarette item. According to them, the cotton wicks used in e-cigarette cartridges may be one source of contamination, as both endotoxin and glucan are known contaminants of cotton fibers. “In addition to inhaling harmful chemicals, e-cig users could also be exposed to biological contaminants like endotoxin and glucan,” said lead author Dr. Mi-Sun Lee, a research fellow at the school. “These new findings should be considered when developing regulatory policies for e-cigarettes,” Lee concluded.
According to the Centers for Disease Control and Prevention, e-cigarette use among American high school students increased by 78 percent between 2017 and 2018, and by 48 percent among middle schoolers.
