摘要:
应用水汽化学的方法学和理论，研究南、北极雪、冰、水中的Zn2+等离子。南、北极雪、冰、水中Zn2+，Cd2+，Pb2+，Cu2+，Sn4+，Bi3+离子含量的空间变化很小，与水汽化学原理计算的离子总平均含量Zn2+ 5.0μg/L，Ch2+ 0.080 μg/L，Pb2+ 0.030μg/L，Cu2+ 0.70μg/L，Sn4+ 0.99μg/L，Bi3+ 0.18μg/L相一致．南北极Zn2+等离子处于自然本底浓度，并处于天然水循环之中。

Abstract:
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+ and Bi3+ in Antarctic and Arctic snow show a significant spatial similarity; they are also close to those defined elsewhere on the basis of the 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 concentrations in the Antarctic and Arctic regions represent natural baseline values and are controlled by natural water cycles.
