- Abstract
The paper reports chemical data on the atmospheric precipitation within the studied area of the Valdai National Park during monitoring in 2015–2018. The main parameters of atmospheric precipitation as well as major and trace-element compositions of waters are analyzed. Seasonal dynamics and possible pathways of element uptake in atmospheric precipitation are considered. Multidimensional statistical analysis (PCCA, RDA analyses) was applied to determine geochemical and anthropogenic factors responsible for the formation of the chemical composition of atmospheric precipitation. Precipitations penetration through tree crown are enriched in organic matter and some elements. The high contents of N, Fe, Mn, Zn, and Cu found in subcrown waters indicate a predominant biogenic migration of the elements with atmospheric fallouts. The elevated contents of Cu and Zn, as well as Cd and Pb in the atmospheric fallouts of the Valdai National Park suggest that the studied area experiences a regional-scale anthropogenic load.
