Volatility of Aerosols in the Western European Environment
Abstract
Volatile properties of marine and modified maritime aerosol were measured at the remote site of Mace Head on the west coast of Ireland, located on the eastern edge of the North Atlantic Ocean. The volatility measurements were made with a light scattering counter equipped with a temperature-controlled heated intake. The work extends the temperature range from 300 deg C to 850 deg C for the first time for aerosol volatility studies. Representative measurements made over the period of nearly two years show that the submicrometer particles with radius < 0.2 micrometer are highly volatile for the maritime aerosol and show temperature-fractionation features of ammonium sulphate (or ammonium bisulphate). It is estimated that 85-95% of this size fraction (by volume) is composed of these sulphates. For the higher temperatures, temperature- fractionation characteristics of sodium chloride are shown for the supermicron and also for the submicron maritime particles. About 80% of the particle size interval of 0.3 - 1.5 micrometers radius is composed of sodium chloride.
