Toxins detected in several e-liquids from the United States? A study published online in Environmental Health Perspectives was conducted by Harvard scientists (Boston, USA) and examined 37 single-use cartridges and 38 e-liquids from 10's best-selling e-cigarette brands in the United States.
According to a recent study, scientists have detected toxins in several e-liquids. The products were categorized into four categories of flavors - tobacco, menthol, fruit and others - and then screened for the presence of endotoxins and glucans, toxic inflammatory bacterial substances that damage the lungs. The analyzes show that 23% of the products contained traces of endotoxin. Traces of glucan have also been found in 81% of the products screened.
« The discovery of these toxins in electronic cigarette products adds to growing concerns about potential adverse respiratory effects in users«, Alert David Christiani, professor of environmental genetics at the Harvard TH Chan School of Public and lead author of this study.
Research also found that endotoxin concentrations were higher in fruit flavored products, indicating that raw materials used in flavor production could be a source of microbial contamination.
According to the authors of the study, the cotton locks used in the manufacture of electronic cigarette cartridges could also represent a potential source of contamination, since endotoxin and glucan may be present in the fibers. " These new discoveries should be taken into account when developing regulatory policies for e-cigarettes", They stress.
