“…The sensitivity of the method depends on factors related to: the amount of energy needed to excite electrons; the amount of X-ray emission; the atomic number of the element under study. 27 The analysis was performed on the Spectron-Optel RMA WD-XRF spectrometer with 46Pd anode ( Figure 6). The quantitative analysis of metals in the peat ash was carried out using certified standards.…”

The metal content was determined using the WD-XRF method in the peat from the Wąpiersk bog and the Las Nadwelski bog (Welski Landscape Park, Poland). The results of the study show that the concentration of metals, especially heavy metals in peat bogs in Welski Landscape Park is low in general. In both bogs, the concentration of heavy metals was lower in the center than on the border. This shows that heavy metals are absorbed by the peat at the border and their further migration is limited. There are more elements such as iron, calcium and magnesium in the Las Nadwelski bog. There is more light on the border of the forest, which also plays an important role in decomposing plant debris, releasing metals. Heavy metals content was higher in Wąpiersk bog – a bog with higher anthropopressure. To sum up, the peat bog actively captures heavy metals, immobilizing them, and acts as a kind of “filter”. Peat is a good agent for retrospective monitoring of metals migration and accumulation in the environment.

“…Three parallel drillcores (FU1, FU3, and FU4) were recovered using a Wacker Neuson DH-65 drill hammer at 47°59′32.5 N, 9°53′13.9 E during a drilling campaign in 2017 [7] . All cores were drilled within a horizontal distance of <1.5 m and were subsequently correlated using lithological marker horizons and well-defined changes in the palynological dataset.…”

Palynological data for the Late Glacial and Holocene (14.5–0 ka BP) from Füramoos, Southern Germany

We here present high-resolution palynological data from the Füramoos peat bog, located in the alpine foreland of Southern Germany. The data represent raw pollen counts of major arboreal pollen as well as agricultural indicator taxa for the Late Glacial and Holocene (14.5 ka BP to present) at Füramoos with an average temporal resolution of 100 years (50 years during critical intervals). The data are also provided as percentages, which are calculated based on the total sum of pollen grains, excluding pollen grains of sedges (Cyperaceae) and strictly aquatic taxa. The data yield insight into the vegetation dynamics in Central Europe in response to climatic and anthropogenic forcing, which are an integral part of the original research article (Kern et al., 2021). Considering its high temporal resolution and the robust age-depth model, the dataset is ideally suited to be included in regional syntheses of vegetation dynamics in Central Europe from the Late Glacial onwards. In addition to the data, we provide a detailed description of the Füramoos site and detail the palynological processing and analysing techniques used.

“…The aforementioned XRF-based techniques are now part of a routine analytical geochemistry toolbox and, since the introduction of XRF-CS, numerous studies have discussed the advantages and pitfalls of these techniques in comparison to spectrometry methods applied to a range of natural archives, e.g., marine [37] and lacustrine sediments [38], speleothems [39] and peat records [25,26,40]. In addition, there have been several attempts to calibrate the most recent XRF scanning methods against more conventional analytical techniques (i.e., ICP) and to convert semi-quantitative data (XRF-based) into quantitative data.…”

“…This paper compares the results of geochemical measurements applied to sediment samples from karst Lake Ighiel, in the Romanian Carpathians (SE Europe), which enable a comparison of the three geochemical methods applied-XRF-CS (ITRAX), FPXRF and ICP-OES. Although comparisons between different methods, e.g., bulk and high-resolution point analyses, e.g., [25,26,38,40], were carried out previously, none of them specifically explored the relationship between XRF-CS, FPXRF and ICP-OES data obtained from a karstic sediment record. To ensure high data reproducibility, the analysis focused on assessing the patterns in a set of lithogenic indicators, Ti, K, Ca, Fe.…”

The paleoclimatic and paleoenvironmental changes inferred from shifts in lake sediment geochemistry require reliable, efficient and cost-effective methods of analysis. The available geochemical techniques, however, suggest that different analytical approaches can influence data interpretation. X-ray fluorescence core scanner analyses (XRF-CS), field portable X-ray fluorescence (FPXRF) and inductively coupled plasma optical emission spectrometry (ICP-OES) were concurrently applied to provide a multi-method geochemical appraisal of a 6000-year-long karstic sediment record (Lake Ighiel, Romania). The comparison between techniques was based on a set of elements that are widely employed in environmental reconstructions (Ti, K, Fe, Ca). Descriptive and statistical approaches were used to assess the advantages and disadvantages of each method and assess their optimal use in karstic environments. Our data display similar downcore patterns, with strong to moderate correlations between the datasets. The discrepancies observed between method-specific downcore multi element behaviour are related to the preparation steps and sampling. To best capture the complexity of past environmental changes in karstic settings, a combination of quantitative and qualitative geochemical methods would be the most appropriate approach to reliable data acquisition and subsequent paleoenvironmental interpretation of lake sediment data.
