Residential wood combustion is an important source of ambient air pollution, accounting for over 25% of fine particulate matter (PM2.5) emissions in Canada. In addition to these ambient contributions, wood smoke pollutants can enter the indoor environment directly when loading or stoking stoves, resulting in a high potential for human exposure. A study of the effectiveness of air cleaners at re...

Results from mathematical modeling of aerosol formation during combustion of woody biomass fuels were compared with results from particle size distribution (PSD) measurements at a pilotscale biomass combustion unit with moving grate and flame tube boiler. The mathematical model is a plug flow model considering coagulation, nucleation, condensation, and particle deposition mechanisms (thermophor...

We thank anonymous referee #2 for the constructive and helpful criticism. A detailed response to the comments of reviewer #2 follows below. Specific comments 1. Title of paper. The title has been changed to better describe the content of the manuscript as suggested by the reviewer: “Contribution of residential wood combustion and other sources to hourly winter aerosol in Northern Sweden d...

Particulate matter emissions (PM10) from open-air burning of dry leaves were sampled and analysed for a series of organic and inorganic species, including carbon fractions, anhydrosugars, humic-like substances (HULIS), water-soluble ions, metals and organic trace components. The study was performed to investigate whether open-air burning of leaves in rural areas is a potential source of high am...

Darin besteht das Wesen der Wissenschaft. Zuerst denkt man an etwas, das wahr sein könnte. Dann sieht man nach, ob es der Fall ist und im Allgemeinen ist es nicht der Fall. Summary Claimed as renewable energy source, wood is increasingly used in stoves and boilers for heating purposes in western countries due to economic reasons and environmental consciousness. Consequently, domestic wood combu...

A brief history of air pollution Accounts of air pollution in the UK date back to the 13 century. Early occurrences resulted from rapid population growth, urbanisation and changes in fuel use – in particular the medieval switch from wood to coal, especially in brick kilns and domestic fireplaces. Coal combustion in industrial furnaces, boilers and, above all, in domestic fireplaces, was the mai...

B combustion is a very large source of aerosol particles on a global scale. It is estimated that 20 % of the black carbon and 30 % of the organic carbon aerosol mass emissions are due to wild land fi res and intentional burning of agricultural waste in Asia. However in those numbers residential fuel combustion is not included, which is considered a larger source of black carbon and organic carb...
