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 Zn2+, Cd2+, Pb2+, Cu2+, Sn4+, Bi3+ 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 Zn2+ 5.0 μg/L, Cd2+ 0.080 μg/L, Pb2+ 0.030 μg/L, Cu2+ 0.70 μg/L, Sn4+ 0.99 μg/L, Bi3+ 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.
