In order to estimate arsenic flux from the English Channel toward the North Sea, 168 samples were obtained from September 1990 to November 1991 along a transect between Boulogne and Folkestone comprising six stations and two depths. Organic and inorganic arsenic were measured in dissolved phase and total arsenic in suspended particles. The mean concentration of dissolved total arsenic in water was 1.38 +/- 0.12 mug.l-1. The variability of measured concentrations was low, particularly for the four intermediate stations. Results were slightly more sensitive for English (1.38 +/- 0.12 mug.l-1) and French (135 +/- 0.11 mug.l-1) coastal stations due to exchanges with shallower sediments. Dissolved organic arsenic was nearly negligible from December to March... |
