Ambient air pollution study Dakar 2005. October - December 2005.

A screening study of air pollution in Dakar was performed between October 2005 and January 2006. Passive samplers of NO2, SO2, VOC and O3 were located at about 50 selected measurement sites in Dakar city and in surrounding suburban areas. A sequential sampler for suspended particles (PM10and PM2,5) and a CO monitor were located at one site in a busy street in the city centre. Parallel and in addition to the sampling programme presented above, short term data of PM10, VOC and CO were collected in selected areas of the city. The main objective with this study was to collect background information for designing a permanent air quality monitoring programme for the area in the future.
