[Stoves] blood analysis as heath impact certification for "clean" stoves

[JF Rozis]

Hi Stovers,

I saw a long time ago very interesting discussions on blood analysis to check CO content within haemoglobin. I don't know if stove producers of cleaner no chimney  fuelwood stoves (whatever the tiers) are systematically specifying minimal air ventilation rate for using their equipments. My aim is to evaluate real health impact of those cleaner stoves (T-Lud, rocket, ..) equipments to be used with some precautions to avoid maintaining health problems. I think tiers scoring of cookstove is always linked with air ventilation rate for no chimney stoves??

Culturally, rural kitchen area in developing countries is a dirty place to be separated for the rest of the home, if integrated is LPG mainly used for richest ones (rural North Marocco by instance), usually well ventilated places in hot climates, more problematic in cold areas where health problems is a huge concern. The risk with so promoting & aggressive marketing I see on Internet on those cleaner stoves, people consider is less or more like LPG and they believe no risk to bring back the cooking place in living areas of the home.

But whatever this evolution, my request today is to know if blood analysis to compare two populations, one using existing stoves in traditional way (with real knowledge on smoke risks, use of adapted biomass,..) and one using those new technology permits to estimate real health impact. It's like for stove performance, field test is only tests giving you real fuel saving with a certain (limited) accuracy, for health impact only field health impact will permit you to check real impact. Is CO content in the haemoglobin a good tracer for health impact?

Is the procedure to limit bias and get minimal accuracy (sampling recommendations and procedures) existing and well validated? Some key persons specialized on this topic in view to prepare such work (feasibility, global cost, ..)


Thanks for your help
