Route66 scrie:Results. The mist contained propylene glycol, ethyl alcohol; nicotine and acetaldehyde
were minor peaks. A different analysis is required to determine whether this acetaldehyde
is artefact or not, as acetaldehyde could have been due to heating of the ethyl alcohol
during GC-MS measurement. Other compounds included pyridine and acetone (probably
from coffee extract flavoring). Acrolein was not detected.17

Acroleina se pare ca exista in cartusele Ruyan , multumesc cercetatorilor din NZ . ( nu stiu daca exista si la noi aceste rezerve . )
According to the U.S. Environmental Protection Agency, the main source of acrolein exposure to humans is the atmosphere, which contains 8.2-24.6 μg acrolein per m3 (mean 14.3 μg/m3) [143]. Acrolein concentrations in smoky indoor air can be much higher. Assuming that human air intake is 10.8 m3/24 h [144], acrolein exposure through atmospheric contact would amount to 154 μg or 2.75 μmol/24 h. This quantity of acrolein is roughly equal to the amount generated by smoking 2.5 cigarettes, which explains why there is a relatively high level of HPMA found in the urine of nonsmokers [11]. In view of the ever-increasing acrolein emissions into the environment, acrolein as a direct irritant may increasingly become a health hazard in individuals with respiratory diseases such as asthma [145].
