Thanks, Kirk. I agree with you that g/MJ-delivered is a better metric and here it is: PM CO Rockets (2x2) 0.7 7.3 Open fire (2) 1.4 15 I will calculate the g/MJ fuel later (I am rushing to leave town). I also have info on optical properties, "EC" content, size distributions, total particle number (all per kg or per MJ delivered)-- for climate forcing calculations. I have not done the trace element/ion analysis, but the measured carbon (EC, OM) looks to account for most of the mass. cheerio Tami - Stoves List Archives and Website: http://www.crest.org/discussion/stoves/current/ http://www.ikweb.com/enuff/public_html/Stoves.html Stoves List Moderators: Ron Larson, ronallarson@qwest.net Alex English, english@adan.kingston.net Elsen L.
