Atmospheric measurements were performed at Tenerife (55 m a sl ) in June-July 1997 Submicron aerosol particles were collected for analyses of mineral dust, ionic and carbonaceous species. Particle size distributions were measured with a differential mobility particle sizer (DMPS). The agreement between the aerosol volume calculated from the chemical composition and the DMPS measurements is excellent. (NH4)×(SO4) y accounts for 70% of the aerosol mass during pollution outbreaks. The contribution of NH4NO3 is always negligible. The relative contribution of organic species is higher in background (25%) than in polluted (9%) conditions. Sea-salt contributes up to 17% to the aerosol mass in background conditions.
