Dear Martin There is no mention there of the fact that babies have a different response to CO than adults. I wonder if perhaps the 250 figure is for young children because the older lower figure seems to be right for adults. Just wondering.
The WHO is lowering the permitted CO from 9 ppm to 7 ppm for long term exposure. Traditional stoves, even ones with chimneys, can be a problem for living area is they are leaky and the living area is not. Some interesting look into this is going on in Ulaanbaatar to see what the effect of insulating and sealing the buildings is going to have on CO exposure. The first tests I did showed a definite rise in the maximum but they are still pretty leaky and the CO does not persist. Putting on super insulating blankets approximately doubled the CO.
