Sampling and Analysis of Aerosols in the Black Sea Atmosphere
Abstract
Atmospheric particulate samples were collected over the Black Sea, using cellulose filters during 1988. The chemical composition of atmospheric particles collected near sea level have been analyzed for 39 elements by nondestructive instrumental neutron activation analysis (INAA) and for SO4 =and NO3 - by ion chromatography. With few exceptions elemental concentrations follow log-normal distribution. The Cl/Na ratio was smaller than the corresponding ratio in seawater, owing to evaporation of Cl from sea salt particles as HC1. This ratio is also inversely related to nss-SO4.
Concentrations of elements in the Black Sea atmosphere were found to be intermediate between continental rural sites where local aerosols and long range transported particles affects observed concentrations and a remote marine site where local sources other than the ocean do not exist.
