“…[17] showed that the soils subjected to stronger weathering had less radiogenic isotopic composition of lead. Our results are consistent with these observations; they also agree with our earlier study of the buried soils near the villages of Salomatino and Peregruznoe in Volgograd region [4].…”

“…During the crystallization of the main lead ore mineral (galena PbS), U and Th are not incorporated into the crystal lattice, and feeding of the lead with radiogenic isotopes ceases. The isotopic composition of the lead extracted from ore deposits and getting involved in biogeochemical cycles in many cases differs from the composition of the lead of local rocks and soils [4]. This allows determining the source and scale of anthropogenic impact.…”

Isotopic compositions of (a) total; (b) acid-soluble; and (c) carbonate-bound lead in buried soil, recent soil remote from roads (horizons A+B+BC), and roadside soils (0-to 5-cm layer); gasoline of Russian production; modern Russian aerosols (shaded zone: mean ± standard deviation); and lead ores of the former Soviet Union [42]; as well as the composition of atmospheric deposition in Europe 4000-4500 years BP (shaded zone: mean ± standard deviation) reconstructed from peat archive data [4]. of the total lead ( 207 Pb/ 206 Pb = 0.840, 208 Pb/ 206 Pb = 2.074, not shown in Fig.…”

“…The comparison of the concentration, isotopic composition, and forms of lead in buried and recent soils can thus contribute to the assessment of the present-day contamination of soils and the determination of the pollution sources. We recently used this approach for assessing the contamination level of recent chestnut soils compared to paleosols buried under burial mounds of the Iron (1700 and 2000 years ago) and Bronze (3500 years ago) Ages [4]. In this work, we study the soil buried under a higher (about 2 m high) and older (about 4500 year old) burial mound.…”

The estimation of soil contamination with anthropogenic lead requires uncontaminated analogues of the recent soils for comparison. For this purpose, a paleosol buried under a 2-m high burial mound of the Bronze Age and protected by it from atmospheric deposition during 4500 years was studied. The content and isotopic composition of mobile and total lead in the buried and recent soils (roadside and remote from lead sources) were compared. Obvious signs of anthropogenic contamination were revealed in only the upper layer of the roadside soil within 10 m from a highway. These were an increase in the absolute content of all lead forms; a high relative content of mobile forms; high ratios of Pb relative to Ti, Zr, and Y; and the similarity between isotopic compositions of the soil lead and the lead from modern atmospheric aerosols and Russian gasoline. Interestingly, no significant difference was found in the total lead contents or in the isotopic compositions between the recent soil remote from roads and the buried soil. However, some signs of anthropogenic impact could be revealed by the analysis of mobile lead forms, which make up a small portion of the total content.
