1) Chemical Composition of Emissions from Urban Sources of Fine Organic Aerosol, Enviromental Sci. Technol., Vol 25, No.4, 1991, paragraph 5 P.755; Single simulated (synthetic) log= 8 grams/hour. log =(11 gr /min x 60 min/1,000x12)=8 grams hour; (6 lb) 2.27Kg = (Petroleum/sawdust mixtures burned in fireplace) averages from 6 to 40 grams.)

1a) Sub micrometer Aerosol Mass distributions of emissions from boiler and fireplaces, automobiles, diesel trucks and meat cooking operations. Aerosol Science and Tech AS&T , Vol 14, P. 138-152, and 1991, Main results table 8 and 9.

2) Mark A. Delucchi, The Contribution of Motor Vehicles and Other Sources to Ambient Air Pollution ,Report #16 in the series: The Annualized Social Cost of Motor-Vehicle Use in the United States, based on 1990-91 Data. Institute of Transportation Studies, University of CA, Davis 8/96; 1994 and newer 14 ton Diesel truck (2 )= 36 grams/hour. 36: hmc: .41gmsx 60km per hour = 25 grams per hour. (well maintained at constant speed hcm)
