Carbon Monoxide from Central African Fires

Published June 18, 2008
Fire is integral to life in much of Africa. As predictable as the rainy and dry seasons, fire sweeps across the continent in a wave that moves north to south following the seasons. In early June, Africa’s fires were concentrated in central Africa. Lightning-ignited fire is part of the natural ecology, but for thousands of years it has also been a tool used by mankind to clear land for new growth, return nutrients to the soil, make charcoal for cooking and fuel, clear debris, and hunt. It is primarily human activity that leads to intense burning in a region during the fire season.

The conspicuous haze over China in mid- to late October 2007 not only obscured the view of the land surface. It also contained substances harder to detect but just as troublesome. Odorless, colorless, and toxic, carbon monoxide can be lethal in large amounts. Additionally, it acts as a precursor to smog and ground-level ozone.
