Characteristics of marine aerosol particles in the southern sea of Korean Peninsula

Abstract

Aerosol particles were collected using high volume aerosol sampler on board in the southern sea of Korean Peninsula between Korean Strait and Jeju island during the periods of November 1997, April, September and November 1998, February and May 1999 to understand the characteristics of marine aerosol particles. There was yellow dust storm in April 1998 during the period of samples collected. Metals, cations, anions, Be-7 and Pb-210 were determined from filter (Whatman 41) samples. The sources of metals in aerosol particles were classified from the enrichment factors normalized by abundances of crust and seawater. Na, Mg, K and Ca were mostly stemmed from seawater, however, the source of Ca was Chinese loess during the event of yellow dust. Al, Ti, Cr, Mn, Co, Zr and rare earth elements were originated from lithogenic materials. Ni, Cu, Zn, As, Mo, Cd and Pb with high crustal enrichment factors were flowed into the study area from artificial sources.May 1999 to understand the characteristics of marine aerosol particles.
