Heavy metals and trace elements in atmospheric fall-out: Their relationship with topsoil and wheat element composition

► Metal and trace element deposition rates and concentrations in bulk samples. ► Anthropogenic vs. natural sources were identified using enrichment factors and PCA. ► Anthropogenic sources for Ca, Cd, Cu, Fe, Mn, Ni, Pb, Sb, U, Zn and lanthanides. ► Main sources were a cement plant, chemical-mechanical industries, cities and mining. ► Metals in wheat grain were predicted by soil and bulk deposition composition.
