Characteristics of metals in atmosphere over the western Taiwan Strait Ⅱ. Sources and fluxes

Atmospheric metals over the western Taiwan Strait are studied and their sources are identified.Al and Fe are mainly from crustal soil.A little amount of Fe is from pollution.Pb and Cd are mainly from pollution sources.A little amount of Pb is from crustal soil and recycled sea spray.Na is mostly from seawater and a little amount of Na is from crustal soil or secondary aerosol particles.Cu is mainly from crustal soil,partly from pollutants,and a little amount from recycled sea spray.Comparing the total inputs of the atmospheric deposition of the metals to the Taiwan Strait waters with the inputs from the rivers shows that the input of Cu from the atmosphere is lower than that from the rivers,and the input of Pb is higher than that from the rivers;the input of Cd is a little higher than that from the nvers.
