This study will examine the chemical processes of soot particles as they age in the atmosphere. It will determine the rate and ability of the particles to take up water and release toxins and their rate of deposition. It will also provide essential information on how quickly toxic constituents formed in the particles are removed by oxidative processes. The work will help in assessing the environmental impact of black carbon particulate emissions and contribute to the development of environmental policies that apply to soot sources such as forest fires and fossil fuel consumption.
