DIRECT DETERMINATION OF LEAD AND CADMIUM DOWN TO SUB pg/g LEVEL IN ANTARCTIC AND GREENLAND SNOW AND ICE BY LASER ATOMIC FLUORESCENCE SPECTROMETRY
We present here the results of the first direct measurements of Pb and Cd in Antarctic and Greenland ancient ice and recent snow at ultralow concentration levels by Laser Excited Atomic Fluorescence Spectrometry with Electrothermal Atomization (LEAF-ETA) in clean room conditions. The limit of detect...
