Ecological and geochemical characteristics of the snow cover in the Yakutsk city (Central Siberia)
For the first time, the geochemistry of snow cover on the territory of the city of Yakutsk, the largest city located in the permafrost zone, is considered on the basis of recent methods of analysis. To study the chemical composition of the snow cover and estimate the ecological state of the city in...
