This paper reviews and summarizes literature about smoke exposure and the resulting adverse health effects among wildland firefighters Many studies have been done on this problem between 1973 and 1995 Overall the data indicate that smoke exposure at wildfires and prescribed…

In this study outputs from four current General Circulation Models (GCMs) were used to project forest fire danger levels in Canada and Russia under a warmer climate. Temperature and precipitation anomalies between 1 x CO2 and 2 x CO2 runs were combined with baseline observed…

Biomass burning, one of the most important global sources of particulate matter, produces both airborne particles that may influence global and regional climate, and particles incorporated into sediments that provide records of past local, regional, and global impacts of biomass…

Smoke produced by vegetation fires consists of a complex mixture of gaseous, liquid, and solid phases. Many particulates are generated during vegetation fires. Crutzen and Andreae (1990) have estimated that global emissions of pyrogenic smoke particles (50-150 Tg yr-l) may…

Fire is an important ecological factor influencing the structure and function of longleaf pine ecosystems, including forest floor and groundcover nutrient pools and availability, forest to atmosphere interactions, and potential nutrient controls on productivity. However, little…

Global annual NO emissions from soil are of the order of 10 Tg NO-N. This is about half the amount fossil fuel combustion processes contribute to the annual global NOx budget. Reducing the emissions of soil derived NOx requires an understanding of the source of the flux and the…

During the spring and summer of 1994 we monitored soil-atmosphere exchanges of methane and carbon dioxide at upland sites in the Canadian boreal forest near the northern study area (NSA) of the Boreal Ecosystem-Atmosphere Study (BOREAS). The effects of fire on methane and carbon…
