These toxins notably included low ranges of benzene, a recognized carcinogen, which was found in 95% of the pure gasoline examined.

The examine additionally discovered that about one in 20 stoves (5%) had gasoline leakage when not in use that was sizable sufficient to advocate follow-up with an professional. The leaks had been usually so small that they could not be detected by the human nostril (pure gasoline is odorized for security), however nonetheless might pose a possible well being threat, in accordance with Drew Michanowicz, a senior scientist at PSE Wholesome Vitality who labored on the examine.
