Re: Cancer breakthrough is a ‘wake-up’ call on danger of air pollution
#2I wanted to find an account of what the biggest sources of PM2.5 are in the US. This article discusses traffic fumes (24% of PM2.5), but I was surprised to learn that by far, the largest source of PM2.5 - 45% - is “unspecified sources of human origin.”
Where does that stuff come from? Well, it’s created in the atmosphere via secondary reactions between agricultural NH3 emissions, SO2 and NOx emissions from shipping and industrial activities and power generation, and NMVOCs from industrial processes and consumption of solvents.[1]
Those reactions seem like an interesting area of study and those chemicals involved are far less-often discussed as sources of air pollution even though they seem to combine to form the biggest source

I wonder how important the raw amount of emissions is. Density should decrease at a cubic rate of distance, so being close to a small source of emissions might be worse than being somewhat far from a heavier source.

See for yourself.
Propublica plotted a "cancer map" of elevated cancer risks, and you can see how it drops off as you go away from certain points.

The other thing people don’t often talk of is PM2.5 inside their home while cooking. Lot of people have poor ventilation or insufficient air movement capacity in their kitchens.

#6Before getting too excited about the experimental prevention they used, IL-1B blockade, let me say that blocking the innate immune system to prevent cancer seems ill-advised. The innate immune system is with us for very good reasons. This would be roughly equivalent to preventing table saw accidents by prophylactically removing all fingers.
Yes, table saw accidents are terrible, but there is a straightforward electromechanical solution (SawStop), and fingers are useful for many other things.
Yes, lung cancer is terrible, but there is a straightforward electromechanical solution (energy from renewables + nuclear), and the innate immune system is useful for many other things.

Well I read the article and got excited about eliminating internal combustion engines...

#8We seem to be getting a lot of "wake up calls" but no one ever seems to answer the god damn phone.

From the food, or the fuel?
