The daily average of PM10 was very high, 179 mu g m(-3) and the BC contents were 4 mu g m(-3). The presence of crustal elements was large in PM(2.5-10) as well as in PM2.5, and had a more than tenfold increase in PM(2.5-10) during the Harmattan period. Major characteristic elements for different sources were identified from correlation coefficients and regression analysis of the data. Sahara sand aerosol was the major source in both study periods, but influence from biomass burning, sea-spray and metal industries was also observed. Copyright (C) 2009 John Wiley & Sons, Ltd.
