Carbon, nitrogen, and sulphur isotope analysis of the Padanian Plain sediments: Backgrounds and provenance indication of the alluvial components

Soil organic carbon data comparison after 85 years and new 13C/12C compositions: The case study of the Ferrara province (Northeastern Italy)

“…According to a one-way ANOVA, there was a highly significantly difference among the districts (p < 0.001), with the δź 3 C values for the LV district being more negative (up to −26.6‰) than the others (Figure 6), indicating the presence of dominance of C3 plant-derived OM in this district. This is supported by the literature, with reports of δź 3 C values for soil OC in Ferrara province ranging from −29‰ to −21‰ (Brombin et al, 2020;Natali et al, 2018Natali et al, , 2021Salani et al, 2021).…”

“…The relationships between soil carbon isotopic composition and the depositional processes identified by Salani et al (2021) are reinforced by Figure 7b, in which sampling points with less negative δ 13 C values are related to relatively highaltitude areas typical of paleochannel, whereas samples with more negative δ 13 C values are located in the lowest altitude areas in the proximity of interfluvial basins. In summary, the use of soil δ 13 C presents an opportunity to evaluate net and gross C changes in carbon stocks over long time scales.…”

Multi stable isotope ratio analysis for the traceability of northern Italian apples

“…The Trento area is famous for the presence of sulfide mineralization; therefore, sulfide minerals in this province, which usually have negative δ 34 S values, are predominant ( Bianchini et al, 2019 ). On the other hand, the δ 34 S values of Ferrara reflect the presence of sulfate minerals in the soil, which are more enriched in 34 S and are abundant in alluvial sediments deposited by the Po River in a large part of the province of Ferrara ( Salani et al, 2021 ). Interestingly, according to the post-hoc test results ( Fig.…”

“…The analyses of S and corresponding isotope ratio 34 S/ 32 S were carried out using an EA vario PYRO Cube (Elementar) operating in combustion mode and coupled with an IRMS precisION (Elementar). C—N analyses were performed following the method described in detail by Bianchini et al (2021) , and S analyses were performed following the method described by Salani, Brombin, Natali, and Bianchini (2021) .…”

High temperature behaviour of Ag-exchanged Y zeolites used for PFAS sequestration from water

“…The methodology coupled elemental analysis-isotope ratio mass spectrometry (EA-IRMS) has been applied to a set of complex environmental matrices. [26][27][28][29][30] Homogenous powdered samples (B10 mg) were weighed in tin capsules, wrapped and, finally, loaded in the elemental analyzer (Vario Micro Cube, Elementar, Langenselbold, Germany) with an autosampler to be analyzed. In this analytical system samples are burnt via flash burning with O 2 at 950 1C in a quartz ''combustion'' tube.…”
