<span class="gmail-break-words"><span dir="ltr">The PM emissions from my
gasifier averaged 9.1 micrograms per cubic meter over 24 hours. In its
definition of a clean cook stove, the World Health Organization
stipulates that PM emissions should not exceed 25 micrograms per cubic
meter. No problem here with respect to particulate matter: 9.1
micrograms is well below 25 micrograms.<br><br>According to WHO
guidelines, carbon monoxide emissions should not exceed 28.40 ppm over a
one hour period. The Lotus Fire Gasifier emitted very little CO over a
one hour period: only 3.925 ppm (well within the WHO guidelines). The
average CO emissions over 24 hours according to the WHO guidelines
should not exceed 5.68 ppm. The average CO emissions of the gasifier was
0.491 ppm (again well within WHO guidelines).<br><br>So my gasifier
easily meets standards set by the World Health Organization in terms of
particulate matter and carbon monoxide emissions. About 50% of
Vietnamese households burn firewood. The health problems associated with
this practice are truly horrendous. Burning firewood is one of the
leading causes of mortality in Vietnam. If these households stopped
burning firewood and used gasifiers, households would be protected from
toxic levels of human carcinogens, and human health in Vietnam would
improve dramatically.</span></span>
