JW50, have you looked at the IVAQS study web page? It's here: IVAQS Project I'm sorry, but I don't have a good idea of when we will have a report on the results, nor much less as to when we can hope that the study will be actually written up for publication. But the facts as I laid them out above are true - that it was always known that the data collection phase was priced separately from the analysis and publication phase, and that all the required funds for the latter were not in when the data collection phase was started. You can see that laid out right on the IVAQS page I linked to above. But I do have personal knowledge of the first data collection run, as I was actually there at the lab for two and a half very long days and two nights. I was invited to be there as an impartial observer essentially, since I have never been a NVC member. It was a very laborious process of running 100 puffs of 4 different liquid samples for 3 different times each through a smoking machine, and then into a collection bag, within which were numerous filters for specified toxicants and compounds. The same process (100 puffs 3 different times) was also carried out with actual cigarettes, and with plain air as a control. The various filters were then tested by more than one scientist in different labs. The raw results, which I have also seen for that first round of data collection, is expressed as quantity per filter per indivdual run of 100 puffs of all the specified compounds being tested for. Of course those numbers are pretty meaningless without context - so all the data has to be analyzed by an air quality expert, as the whole purpose of the study is to determine what and to what extent, if anything, bystanders would be exposed to in indoor spaces where ecigs are being used. Those raw numbers have to be interpolated into a meaningful amount per cubic meter in rooms of given sizes of the tested for compounds, and compared, for example, to the results from existing studies of second hand smoke and other well known sources of indoor air contaminents. The second data collection run, that I did not witness but have no doubt did take place, was just that - a second run of all the smoke machine puffing and collecting done the first time, with the same 4 different eliquids, cigarettes and plain air. I hope that helps.
