Hey, That study was in 2005, the most recent WHO report said approximatley 2 million per year, in November 2009.
Find it here http://content.undp.org/go/cms-service/stream/asset/?asset_id=2205620 , or go direct to their site The UNDP/WHO 2009 report, The Energy Access Situation in Developing Countries, A Review Focusing on the Least Developed Countries and Sub-Saharan Africa, can be downloaded from http://www.undp.org/energy The problem is that these figures from the WHO are extremely conservatve, and only relate to direct death caused from cooking smoke as referenced in multiple independant studies. Primarily this is pneumonia in children under 5, COPD and lung cancer (especially with coal). It does not, however, include the related deaths. So, for example, if your TB is made significantly worse by smoke inhalation and you subsequently die, this death is not recorede in absolute terms or in loss of years as a smoke consequence. Other involved studies are not included in these figures as they are simply not backed up by enough other studies, there must be 15 - 20 studies shown hence only 3 main related sicknesses. Athsma, cateracts, still births and perinatal mortality as well as other respitory and heart issues are all linked by study, but not backed up enough to have as published figures. See page 48 of the above paper. Cateracts, for example, will cause significant loss of welfare in a community, but rarely kill...and so on. The figure, all inclusive could be as high as 6 million per year, but that is difficult to prove exactly. Hope this helps, depressing as it is.

Cooking and heating with such solid fuels on open fires or stoves without chimneys leads to indoor air pollution... Exposure is particularly high among women and children, who spend the most time near the domestic hearth. Every year, indoor air pollution is responsible for the death of 1.6 million people - that's one death every 20 seconds."

Christa Roth http://terrapreta.bioenergylists.org/files/2010%20biochar-bq%20demonstration %20by%20Christa%20Roth.pdf What student projects can demonstrate the ability of biochar to capture nutrients and retain them for plant growth? Nutrient capture: are there simple leaching or column tests where students can filter a known concentration of fertilizer elements through samples of soil with and without biochar and directly measure the concentration in the filtrate using something like a specific ion electrode or conductivity tester e.g. K or nitrates, or heavy metals like Pb, or Cd? Greenhouse/pot tests: can the students then test the same media with and without biochar in pot tests? A students recently asked if there is a way that she can measure the amount of carbon in biochar that will be available for carbon sequestration. Any examples or ideas?
