Abstract

Abstract

One hundred and eighty one aerosol samples,and two cascade impactor samples were collected in the atmosphere over the western Taiwan Strait from 1991 to 1993.Concentrations of Al,Fe.Cu,Pb,Cd,and Na were determined by an atomic absorption spectrophotometry.The contents of Fe,Cu,Pb and Cd in the atmosphere over the western Taiwan Strait were lower than those over inland cities in China,Europe or North America.Annual and seasonal variations of concentrations of the metals could be primarily attributed to washout or monsoon for non sea salt metals.Fe was presented in bimodel distributions with size around 3.6 μm and 0.52μm Al was chiefly distributed on the particles with size less than 2.1 μm,Na on the particles with size greater than or equal to 3.6 μm,and the size distributions of Cu,Pb and Cd were presented in small particles.chiefly on those with size less than or equal to 0.52 μm.
