The topic of this study is on the links between the personal use of urban transportation and lead emissions in African capital cities. Its objective is: 1) to generate lead emissions at the household level; 2) to measure and analyze the specific impacts of the household's and the individual's characteristics on lead emissions. A 2000 Mobility survey in the urban district of Ouagadougou, is the main data source. Firstly, the emissions at the household's level are estimated. Then, an operational adapted IPAT multi-level model is defined in which the level of emissions is the dependent variable while the set of explanatory variables characterize the household (residential mobility, duration of formation, type of motorization, dependency ratio, schooling, sector of employment) or its head (gender, age, level of education). Finally, a research and a policy agendas are defined with respect to this environmental threat and to the local channels of contamination.
