Abstract
Aerosol particle samples have been collected for the first time at a coastal monitoring site in Cape D'Aguilar, Hong Kong. The site is situated on the coast of the South China Sea and the West Pacific Ocean, located 60 m above sea level at 114*15′E, 22*13′N. Inorganic compounds including major ions and various trace elements were measured by ionic chromatography (IC), neutron activation analysis (NAA), and X-ray fluorescence spectrometry (XRF) on total suspended particulate (TSP) and PM10, respirable suspended particulate(RSP). The results of the sampling program carried out between May 1993 and May 1994 are presented. The data obtained show that sea salts, crustal compounds, sulfate and nitrate are major components. Most trace elements have roughly the same concentrations in the total and the PM10fraction. The enrichment factors of RSP are generally higher than those of TSP. The origins of particles are further discussed following enrichment factor analysis.
