BIOGEOCHEMICAL LICHEN-INDICATION STUDY OF THE STATE AND DYNAMICS OF THE ATMOSPHERIC POLLUTION OF THE ARBORETUM OF THE FALZ-FEIN BIOSPHERE RESERVE "ASKANIA NOVA"

By the method of biogeochemical lichen indication on territory arboretum Falz-Fein Biosphere Reserve "Askania-Nova" (Kherson Region, UKRAINE) temporal trends (2011-2021) in concentrations heavy metals and other micro- macro-elements epiphytic lichens was estimated. The samples Parmelia sulcata, Xanthoria parietina Evernia prunastri collected 2011 (39 sites) 2021 (44 for concetrations 22 chemical elements (Al, B, Ba, Ca, Cd, Cr, Co, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, S, Sb, Se, Sr, Ti, V Zn) by ICP-OES spectroscopy were analysed. In order to correctly compare different species lichens, their intercalibration base P. sulcata carried out calibration coefficients, so-called indicies (BGCHL indicies), calculated. Based these arithmetically averaged hypothetical at sites, where absent, calculated corresponding databases element all three created. Factor analysis applied identify possible sources determined period (Fa-1 – Fa-8) (Fb-1 Fb-8). eight resulting factors represent crust anthropogenic components. Some interpreted as being associated with agricultural activities, microclimate, pH atmospheric precipitation higher plants factor (leaching еlements absorption lichens). structure growing studied area formed under regional conditions accumulation well a decrease such V, Zn, S Se. Moreover, Sb Ba have spatially heterogeneous dynamics concetrations, Se has very decreasing trend concentrations.
