Atmospheric transport and deposition of anthropogenic substances from the Asia to the East China Sea

Experiments conducted aboard the R/V Hakuho Maru (Cruise KH-02-3) in the autumn of 2002 were designed to study the pathways of atmospheric aerosol transport, selected trace elements and major ions composition of particles and quantify their dry deposition over the East China Sea. We determined the concentrations of trace elements Al, Mn, Pb, Se, and Zn and major ions Na +, SO 4 2− and NO 3 − in aerosol particles. Aerosols were continuously collected in fine and coarse size fractions with a cut off at 2.5 μm. Particle number densities (volumes) were determined in four size ranges between 0.1 and
