Lead and its isotopic ratios in atmospheric precipitation in the Baikal region and Primorski Krai

N.A. Onishchuk, T.V. Khodzher, E.P. Chebykin, and E.V. Chipanina

Presented are the results from investigating the lead isotopic composition in atmospheric precipitation in the Baikal region and Primorski Krai. It is established that at three stations of the Baikal region, differing in their physical-geographical location and in the degree of anthropogenic influence, the isotopic ratios are similar to those for lead ores of Kazakhstan, the main supplier of lead to Russia. Atmospheric precipitation in Primorski Krai is intermittently influenced by the trans-boundary transport of atmospheric impurities from industrial areas of China.
