Air particulate samples were collected from the Black Sea atmosphere, using cellulose filters in the summer of 1988. Lead and nickel concentrations in aerosols collected at 10 m above sea level were determined by using electrothermal atomization atomic absorption spectrometry (ETA-AAS). Concentrations of Pb and Ni were high in the western part of the Black Sea, owing to strong influence of anthropogenic sources. Lead was highly enriched in the Black Sea aerosols due to the significant contribution of motor vehicle emissions, while Ni was moderately enriched. The Pb/Br ratio was higher than the corresponding ratio in fresh motor vehicle emissions, owing to evaporation of Br from particles. Atmospheric flux of Pb to the Black Sea was higher than riverain flux, while the opposite was observed for Ni.
