Seasonal variability of biomass open burning activities in the greater Mekong sub-region

The seasonal variability of biomass open burning activities in the Greater Mekong sub-region (GMS) with focus on carbon monoxide (CO) and total particulate matter or aerosol (TPM) emissions was investigated in order to document the characteristics of this significant source of air pollutants in the region.

The burning issue

Fortunately for us, carbon monoxide (CO)—a toxic gas—is a very minor constituent of the atmosphere. It is produced by incomplete burning of fossil fuels and biomass (such as dry leaves and wood) and by the oxidation of methane and other volatile hydrocarbons in the atmosphere. http://www.sciencemag.org/content/330/6011/1636.summary

Large variations in Southern Hemisphere biomass burning during the last 650 years

We present a 650-year Antarctic ice core record of concentration and isotopic ratios (δ13C and δ18O) of atmospheric carbon monoxide. Concentrations decreased by ~25% (14 parts per billion by volume) from the mid-1300s to the 1600s then recovered completely by the late 1800s. δ13C and δ18O decreased by about 2 …

Structural basis of biological N2O generation by bacterial nitric oxide reductase

Nitric oxide reductase (NOR) is an iron-containing enzyme that catalyzes the reduction of nitric oxide (NO) to generate a major greenhouse gas, nitrous oxide (N2O).
