Abstract

During a series of oceanographic cruises (December 1993, June 1994, December 1994, and July 1997) in the area of the buoy “ODAS Italia 1” in the Ligurian Sea (43° 48.90′N 09° 06.80′E), a new sampling bottle for deep sampling of sea water for trace metals analysis at ng/l level was tested. The reactive mercury concentration was determined directly on board the oceanographic vessel, immediately after the sampling by reduction with tin(II) chloride, pre-concentration on gold, and atomic fluorescence detection. Mercury concentrations ranged between 0.06 and 0.90 ng/L with an average of 0.22 ng/l for samples collected in December 1993, June and December 1994. Higher values were found (mean 0.41 ng/l, range 0.27–0.61 ng/l) in samples collected in July 1997.
