Trace elements in the atmosphere over the North Atlantic
One major component of the aerosol was atmospheric dust, and the ranking for the median mineral dust concentrations as represented by aluminum was BAT > IZT > BTT > MHT. The al concentrations at BAT, IZT, and BTT ranged over 4 orders of magnitude, ie, from 0.001 to 10μg m-3. At MHT the maxi...
