Characteristics of trace metals in marine aerosols and their source identification over the Southern Ocean
Atmospheric trace metals (Cu, Zn, Cd, Pb, Fe, V, and Cr), As, Al and Na in marine aerosols were studied over the Southern Ocean during the 28th Chinese National Antarctic Research Expedition. Fe was the most abundant of the analyzed trace metals, with an average concentration of 28.824 ng∙m-3. V and...
