“…In parallel, a search for further historical data sources of the Saxony-Anhalt region was prepared. Most of the searched databases proved to be inapplicable for the purpose of geogenic metal concentrations in the rivers of Saxony-Anhalt due to several reasons: the data have been obtained for soils [20,21] or sediments [42], they have been obtained for neighboring geographic regions, especially Lower-Saxony, showing an anthropogenic influence by acid rain [20], or historical data which have been secret due to former Soviet-union exploration activities in certain regions, like the Harz Mountains [42]. This situation led to a remaining database for the validation of the investigation results, the "Geochemical Map of the Metal Concentrations in the Rivers of Germany" according to Birke et al [41] applicable for the benchmarking process, which is based on the 50th and 90th percentiles.…”

Geogenic concentrations are defined as those concentrations that represent the natural background without any anthropogenic influence. The paper describes a statistical method for determining geogenic metal concentrations in rivers based on the concept of "aggregated riverine landscapes" (ARLs), which applies to all rivers in the Federal State of Saxony-Anhalt (Germany). The methodology includes the pre-selection of existing data by eliminating all sampling locations from the database which have anthropogenic influence, the GIS-based allocation of the sampling locations with respect to the respective ARL being the evaluation units, and the assessment of the geogenic background by statistical calculation of the 90th percentile. After validation of the methodology, the existing database was complemented by additional measurements for regions with data gaps. About 85,000 records of water samples, 1400 records of sediment samples, and 920 records of suspended particulate samples were used for the determination of the geogenic metal concentrations in the rivers of Saxony-Anhalt. The investigation included the parameters Al, Ag, As, B, Ba, Be, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Se, Ti, U, V, and Zn. The investigation results offer the determination of regions with increased background levels for certain metals or metalloids in Saxony-Anhalt.

“…The catchment background levels were defined empirically (Matschullat, Ottenstein, & Reimann 1999). The mean values of the concentrations from overbank deposits in Section 2 (Table I), accumulated before the Bronze Age, were used to assess the geological background element concentrations.…”

Indirect dating of historical land use through mining: Linking heavy metal analyses of fluvial deposits to archaeobotanical data and written accounts

Man-made heavy metal contamination of floodplains has existed for centuries-even dating back to the Middle Ages. Up to now, these contaminants have been analyzed with very timeconsuming and costly techniques. Thus, to determine historical heavy metal contamination, the aim of this study is to link the following approaches to generate better comprehensive and interdisciplinary understanding of historical land use of the Inde River, Germany: (1) to analyze anthropogenic heavy metal contamination of fluvial deposits from before ca. 2800 B.C. onward; (2) to investigate the historical land use by applying archaeobotanical data; and (3) to weave information from written accounts, in order to indirectly date fluvial deposits. In this study, heavy metal concentrations were measured in situ using X-ray fluorescence spectroscopy. Subsequently, pollen and macroremains dating from the Early Modern Period were archaeobotanically analyzed. Finally, historical accounts were studied. We found that fluvial deposits of varying age show distinctly different concentrations of lead, zinc, and copper. Moreover, the archaeobotanical analyses indicated intensive land use through farming, husbandry, and forestry. Finally, the written accounts described mining activities since the Roman Period or even before. In conclusion, linking these three interdisciplinary approaches is ideal for gaining insight into the historical anthropogenic impact on the environment.
