The some trace elements in the Antarctic and Arctic snow, ice, water were studied using the methodology and theory of water vapor chemistry. The concentrations of ions Zn 2+ , Cd 2+ , Pb 2+ , Cu 2+ , Sn 4+ , Bi 3+ in Antarctic and Arctic snow a significant spatial similarity; they are also close to those defined elsewhere on the basic of studies of water vapor chemistry: on average Zn 2+ 5.0 μg/L, Cd 2+ 0.080 μg/L, Pb 2+ 0.030 μg/L, Cu 2+ 0.70 μg/L, Sn 4+ 0.99 μg/L, Bi 3+ 0.18 μg/L. Apparently, the ion concentration in the Antarctic and Arctic region represent natural baseline values and are controlled by natural water cycles. 展开更多

There was a complete set of cross-polar distributive data of nitrate (NO<sub>3</sub><sup>-</sup>) content inthe surface snow of the Antarctic ice sheet along the route of the 1990 International Trans-Antarctica Expedition. We have shown the profiles of nitrate concentration and flux alongthe route as the plots associated with geomagnetic latitude for further analysis on the 展开更多
