Abstract
This study investigates the biological absorption coefficients (BAC) of chemical elements in peach, almond, and pistachio trees grown on colmatated oasis soils. Macro-, micro-, trace-, lanthanide-, and toxic elements were analyzed and compared with lithospheric Clarke values and soil concentrations. The results show that almond actively accumulates Ca, Mn, and As, whereas pistachio demonstrates relatively higher BAC for Zn, Se, and Hg. Peach exhibits stable uptake of K and Ca and conservative absorption of microelements. Differences in element accumulation reflect plant physiological adaptation, soil colmatation degree, and geochemical mobility of elements.
