Оценка загрязнения почвы тяжелыми металлами вследствие медеплавильного производства в бронзовом веке

Abstract

Heavy metal content in soils from different Bronze Age fortified settlements (Southern Urals) was determined by ICP-MS in order to trace ancient smelting activities. The enrich-ment factors (EF) for Cu, Zn, Pb, Cd and Sr were calculated. Low EF values (not exceeding 5) indicated minimal to moderate metal enrichment. Gradual increase in heavy metal EF from lower to superficial layers was observed for Konoplyanka soil section. Heavy metal EF’s in top-soils were higher than in lower clay loam layers.
