| Abstract: | A determination method of copper ,lead and cadmium in the marine aerosol by AAS,saniples using a large volume atmospheric sampler and through Wahtman 41 # filter and digestion method with nitricerchloric acid were presented. Volume correction, various filters,AAS measurement and the digestion methods were compared and discussed. The detection limits for copper, lead and cadrnium were 1.8ng/m3,1.4ng/m3 and 0. 7ng/m3 respectively.The coefficients of variation for copper, lead and cadmium were 9. 6%,8. 9% and 1.8% respectively. |
