    Pre-Roman copper industry had no polluting impact on the global environment by Omri Yagel, Aaron Greener, Willie Ondricek, Erez Ben-Yosef

    Published 2024-11-01
    “…Based on high-resolution pXRF geochemical surveys of two smelting camps from different periods, accompanied by test excavations, we demonstrate that (1) mapping elemental concentrations in soil is an effective tool for identifying and characterizing various activity areas in archaeological sites, such as metal production, livestock penning and domestic and industrial waste disposal; (2) in Timna, the intra-site organization of production and scale of metallurgical activities changed substantially between the Early Bronze Age and the Iron Age; (3) the heavy metal enrichment (Cu/Pb) of soil due to smelting is spatially discrete, concentrated only in areas directly associated with these activities; and (4) this enrichment aligns with the spatial distribution of metallurgical waste, suggesting that lead emission to the atmosphere was minimal and that the documented heavy metals are not bioavailable. …”
