That way it is easy to ascribe intents, purposes, and outcomes that were not intended by the authors. If you just read abstracts, how credible are your conclusions about anything? I guess if you are the leading expert on cookstoves and health then you can just read the headlines and forget about the content. Or, you could take the work seriously and discuss the work directly with the authors, some of whom are subscribed to this discussion list. Call Jim Jetter at EPA or pay him a visit.

The latter should be further divided into emissions that are due to the stove design and those due to how the stove is operated. The Shen paper should be read with that in mind to see if the way the device has been operated has an impact on the emissions. Differences in emissions at high power, low power, startup, steady state, are discussed. Morphology of the particles and organic vs inorganic composition is discussed. Occurrence of soot is identified. The study points out the lack of data for particulate emissions from cookstoves compared with other combustion sources.
