<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif">I think this is a bit over the top:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif">“This did not allow the smog and dust to disperse into higher atmosphere, thereby creating death chamber like conditions on the ground.”<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif">It is common hear claims that breathing air in such-and-such a place is “like smoking 2 packs of cigarettes a day”. I provided here at least one calculation of what people are
exposed to in a city.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif">First, PM is not equally toxic. The agricultural residue burning makes really ‘bad smoke’ stinging the eyes at 400 µg/m3. Coal smoke and vehicle smoke has nothing like the same
effect, with the proviso that coal smoke varies a lot depending on what the source device is. Having experienced 3000 µg/m3 I can report that stubble burning is way worse than coal smoke.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif">Second, just because someone places a number on paper does not make people sick. People who have ‘pre-existing conditions’ are at risk from all sorts of things. One of my childhood
neighbours, an adult woman, was allergic to house dust and lived in a hermetically sealed home – but smoked! There is no pleasing some people…<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif">So…the photo in the article is taken over a long distance and zoomed, so you are looking ‘through’ perhaps a km or more of air. The BBC frequently shows pictures in Beijing taken
in the same way – showing morning mist as ‘pollution’ when there really isn’t much to show. How bad is Delhi air compared with living in an apartment in which one person smokes? Do the math. There is no city air as bad as sharing a flat with a smoker.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Arial",sans-serif">The smouldering garbage and wet leaves story is typical of
<i>real</i> pollution in cities. Absolutely awful with a huge emission rate per kg. The inversion in Delhi is a good example of what happens in Ulaanbaatar in winter – daily. Sometimes there is no wind, like last winter. Living in the city was like smoking
¼ of a cigarette per day in terms of exposure. I am not recommending it, but it is completely untrue that it is like ‘smoking 2 packs a day’.
