[The ionic composition of the atmospheric aerosols in industrial areas of the north of Spain].
Over the years 1986, 1987 and 1988 determinations of the mass concentration of total particles in suspension and of the anionic components (chlorides, nitrates and sulphates) and cationic (sodium, potassium, calcium, magnesium and ammonia) contained in these was carried out in Bilbao, Sestao and Erandio. The determination of the mass of particles was carried out by gravimetry and chemical composition by ionic chromatography. The particle concentrations in Bilbao and Sestao, over the measuring period, were higher than those in Erandio. The studies of concentrations, percentages and correlations show the existence of centres of calcium emission during one season and high levels of chlorides during all of them. Surprisingly enough, the nitrate and ammonia content for all the seasons is low in comparison with other urban and industrial centres of the peninsular inland.
