摘要

Emissions of carbon monoxide (CO), particulate matter (PM), and benzo(a)pyrene (BaP) were measured during prescribed burning of four fine fuels of the Southeastern United States by both backing fires and heading fires. Mean emission factors for CO ranged from 57 to 114 g/kg, for PM from 13 to 39 g/kg, and for BaP from 0.22 to 0.76 mg/kg. These values are within the range found by other workers in similar fuels. Emission factors appeared to be influenced somewhat by fuel type and fire type for all three emission products. Emission rates for CO ranged from 0.14 to 1.04 g/m/s, for PM from 0.03 to 0.41 g/m/s, and for BaP from 1.00 to 8.83 g/m/s. These emission rates are meaningful only for the fuel and weather conditions under which they were monitored. Emission rates generally fluctuated more than emission factors.
