An inventory of particulate matter and air toxic emissions from prescribed fires in the USA for 1989
This report documents a prescribed fire emissions inventory developed using consistent methodology for each of the 50 states of the USA for calendar year 1989. Emissions of particulate matter, selected toxic compounds, and a few other carbon-containing...
