Abstract

Sampling of total gaseous mercury (TGM) in air was initiated at Alert, Northwest Territories, Canada (82.5°N;62.3°W) by Atmospheric Environment Service (AES) staff during August 1992 on an exploratory basis for a year. TGM was pre-concentrated onto traps (2 in series) containing Au-coated quartz sand for sampling periods of 1 (or more) week(s) at flow-rates of 30 – 50 mL/min. During the first winter cruise of the RV “POLARSTERN” from Germany (56°N) to the Nordic Seas, and at an ice-camp (81°N;5°E) in the Arctic, simultaneous samples of TGM and aerosol black carbon (“soot”) were collected, from February to April 1993, by the GKSS group. The analytical methods for TGM determinations (2-stage gold amalgamation/thermal desorption, followed by cold-vapor atomic fluorescence spectroscopy) were essentially the same for both studies. Experimental details, results, and conclusions are presented and discussed.
