| In the region of South-Atlantic anticyclonic circulation total concentration of zinc and copper in oceanic water ranged within 1.5-17 and 1.8-6.2 mg/l, respectively. The concentration of dissolved mineral zinc varied from 0.0 to 5.8 mg/l, that of dissolved mineral copper - from 0.0 to 2.2 mg/l, that of dissolved organic complex of zinc and of copper - within 0.4-3.6 mg/l and 0.3-1.1 mg/l, respectively. Particulate zinc ranged within 0.18-1.25 mg/l and copper within 0.22 to 3.6 mg/l. Concentration of trace elements in water and their forms ratio depended on regional hydrological conditions. Concentration of zinc in oceanic plankton varied from 3.6 to 124.6 mg/kg, that of copper and manganese - within 1.0-27.4 and 0.2-6.7 mg/kg (wet mass), respectively,... |
