<p class=MsoNormal style='margin-bottom:12.0pt'>Rich theories make some people
rich. <br>
<br>
As with stove design and promotion, context is everything. <br>
<br>
Considering that practically no data exist on low dosages of ultrafine
particles, nor is any causal pathway from such dosage to disease incidence,
toxicity claims of the type you have found are useless from policy
perspective. <br>
<br>
Maniacal chatter is not science.<br>
<br>
Preventing exposures to ultrafine particles may or may not prevent premature
deaths. Even Kirk Smith and Ajay Pilarisetti accept as much, considering their
methodologies for aDALY computations. <br>
<br>
Say, Ebola is spread by just one virus and preventing the emergence or the
spread of the virus would prevent premature death. There is no similar
potential with ultrafine particles generally. Too many sources, varying
compositions, confounding factors.<br>
<br>
Ultrafine particle emissions are a new fad in cookstove business. Fads kill
people by omission. Whether any premature death was from hunger or HAP exposure
or contaminated alcohol, nobody would ever know. <br>
<br>
I propose the ISO process be subjected to premature death. <br>
