Short summary
Atmospheric aerosol was sampled in Cabo Verde and analysed for chemical composition. Very high levels of dust were measured during the winter months, as a result of transport from Africa. Mass balances were applied to the particulate material, permitting the determination of seven different source contributions to the aerosol loading. The balance methodology compared favourably with standard source apportionment methods, showing its capability for the source apportionment of aerosol particles.
