Reading the article, it's not clear from they detected any of these chemicals in concentrations that are known to be unhealthy. People who got "popcorn lung" were exposed to comparatively massive doses.
- isch 11y agoThere was a study last year that analysed diacetyl concentrations in common e-liquids. They found that 47% of 159 preparations examined were above the safety guidelines for daily consumption >The median daily exposure levels were 56 μg/day ... They were slightly lower than the strict NIOSH-defined safety limits for occupational exposure ... however, 47.3% of DA and 41.5% of AP-containing samples exposed consumers to levels higher than the safety limits. http://ntr.oxfordjournals.org/content/early/2014/09/23/ntr.ntu176 http://ntr.oxfordjournals.org/content/early/2014/09/23/ntr.n... Compared to this recent study, this shows that addition of diacetyl and in what concentration is decreasing.
