Over the recent few decades, due to climate warming and continuing exploration of Arctic seas’ mineral resources, scientific interest in contamination problems has deepened significantly. In this study, for first time, we characterize distribution features 47 elements (major trace elements, including heavy metals, metalloid As, Cs-137 technogenic radionuclide) surface bottom sediments from some areas Barents, Kara, Laptev, East-Siberian Seas. The lithogenic material was main factor that...
Numerous studies have considered whether run-off from large Siberian rivers, in particular the Ob River, has potential to transport radioactive contaminants nuclear sites – SPA "Mayak" and Chemical Combine (SCC), located vicinity of these distant locations including Kara Sea.
In the presented work, features of distribution Cs-137 and plutonium isotopes in modern sediments various parts Laptev Sea, selected during expedition studies on RV “Academician Mstislav Keldysh” 2017 2019, were studied. It was found that activity water is within global level, which typical for seas Arctic region. all collected samples specific content Pu-239,240 below level minimum detectable activity. According to results isotope analysis Pb-210, sedimentation rates two columns Sea are...
During the expedition on Akademik Mstislav Keldysh research vessel in 2016 year it was established that content of radioactive cesium sea water Novaya Zemlya archipelago bays and open are at a level corresponding to global fallout (1 Bq /m3). Plutonium is slightly higher .The activity neptunium
 an order magnitude than plutonium (0.761.89 Bq/m3), although its almost two orders lower content. The bottom sediments Kara Sea 0.23.8 Bq/kg. as high possible mouth Yenisei River (up 21 Bq/kg)...
