Particulate, black carbon and organic emissions from small-scale residential wood combustion appliances in Switzerland

Abstract An inventory of annual and monthly emissions from small-scale residential wood combustion in Switzerland was prepared. Emissions from seven single room appliance classes ( 10 , PM 2.5 and PM 1 , respectively). Annual emissions were determined for each emissions species (base year 2009). The hardwood softwood mix was assumed to be 57:43 and the mix of current and modern appliances was assumed to be 70:30. For the current emission scenario, annual TPE was calculated to be ∼4.35 kt y −1 , of which 39% was BC and 42% POM. TOC emissions were calculated to be ∼3.82 kt y −1 for the same period and scenario. Analysis of the size dependency of PM was also made. PM 2.5 dominated all combustion scenarios, contributing 76–85% of TPE.
