<br>1. I don't think Crispin has any basis to claim IAP wouldn't change much if stoves were electrical. Perhaps with the lowest-emission coal stoves, but not compared to traditional stoves, fuels, operating practices, and ger design (or for HOBs in UB and Aimac centers). <br><br>2. It is meaningless to distinguish OAP and IAP. What matters is exposures, according to age/sex/medical condition/duration according to concentration and composition. I hold that the PM2.5 concentration is a weak proxy for exposures, and the assumptions of equitoxicity, no threshold are simply untenable. Then you add the rigmarole of Integrated Exposure Response to compute Relative Risk, using data for one type of PM2.5 for one type of cohort and then apply it to anybody everywhere. This is not just nonsense, it is becoming an intellectual nuisance. <br><br>3. Using chimneys, or burning coal in a central power plant equipped with PM and SO2 controls to deliver electricity to home use, changes the composition and location, residence times of pollutants. "Outdoors" - which is a contextual term - some pollutants react in presence of sunlight to produce a different composition of pollutants. One may do source apportionment studies of varying quality, assumptions, and data sources. For UB, the contribution of stoves, cars, power plants, industry, building boilers, dust storms, etc. would vary by time of day and season. <br><br>A lot of public health dogma rides on faith. But we need dogma to focus people's attention. <br><br>If God gives us dogma, the Devil is in the details. <br><br>You imagine "<span style="color:rgb(31,73,125);font-family:Calibri,sans-serif;font-size:14.6667px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">solutions are relatively straight-forward".  </span>Not so. Localized air-quality management plans take an enormous amount of systematic work. Changing or banning fuels or devices - or for that matter, people (what would it take to dislocate all the poor and throw them miles away?) - is an easy answer for people who don't bother with economics, politics, totality of population health over long periods. <br><br>Nikhil<br><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><font face="georgia, serif">------------------------------------------------------------------------<br>Nikhil Desai</font></div><div><span style="font-family:georgia,serif;font-size:small">(US +1) 202 568 5831</span><font face="georgia, serif"><br><i>Skype: nikhildesai888</i><br></font><br></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>

that the situation is a bit more complex than the one presented the WHO reports

  <li class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">There isn’t much air
      pollution now indoors so it would probably not be reduced. In a home
      where no one smokes and they have a typical Stove Programme stove, the majority

  <li class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">Respiratory infections are

      now (which means ‘chronically cold all the time’) the rate
      would probably not change much. This was demonstrated in Kyrgyzstan when
      it was shown that increasing the average temperature 5 degrees and
      heating for more than 16 hrs per day instead of 2-6 there was a huge
      medical health benefit – nothing to do with smoke. Being
      chronically cold in a stove-smoke-free environment would help reduce eye

      temperature all day from traditional stoves going from zero to 40 kW then
      back to zero. Electric heating would moderate that, presumable, but you

      the considerable fugitive dust created by those vehicles on dirt roads.
      Dust storms are 50 times worse than air pollution from people.
