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

The main causes of soil organic matter (SOM) loss are land use (e.g., conventional agriculture) and land-use change (e.

The trace element distribution in peat soils affected by natural burning events: A proxy of the original composition and metals mobility assessment.

This work evaluates for the first time the effects on the trace element composition of peat soils affected by natural burning events, a recurrent phenomenon in the reclaimed wetland of the Mezzano Lowland (Padanian plain, NE Italy). The trace element distribution of two neighboring soil profiles, one pristine and one deeply affected by burning events, were compared to identify the original geochemical fingerprint of saltmarsh peat environment. The pre-combustion composition of the fired profile was reconstructed to infer the physico-chemical changes occurred as a consequence of the burning event, with a special attention to the mobility of elements of environmental concern, such as potentially toxic trace metals.

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

Per- and polyfluorinated alkyl substances (PFAS) are anthropogenic compounds which have recently drawn great attention due to their high biological, chemical and physical stability and lipid/water repelling properties. The present work aims to provide for the first time insights on the thermal behaviour of Ag-exchanged Y zeolite loaded with perfluorooctanoic acid (PFOA, CHFO) and perfluorooctane sulfonate (PFOS, CHFOS) emphasizing the close link between crystal structure and desorption/dehydration processes. Elemental and isotopic abundance of carbon analysis, thermal analysis, and high-temperature synchrotron X-ray powder diffraction were used to evaluate critically if the thermal regeneration affects the initial zeolites structural features.

Peat Soil Burning in the Mezzano Lowland (Po Plain, Italy): Triggering Mechanisms and Environmental Consequences.

The effects of peat burning on organic-rich agricultural soils of the Mezzano Lowland (NE Italy) were evaluated on soil profiles variously affected by smoldering. Profiles were investigated for pH, electrical conductivity, bulk density, elemental and isotopic composition of distinct carbon (and nitrogen) fractions. The results suggest that the horizons affected by carbon loss lie at depths 10-70 cm, where the highest temperatures are developed.

Traceability and Authentication of Manila Clams from North-Western Adriatic Lagoons Using C and N Stable Isotope Analysis.

In the Adriatic lagoons of northern Italy, manila clam () farming provides important socio-economic returns and local clams should be registered with the Protected Designations of Origin scheme. Therefore, there is a need for the development of rapid, cost-effective tests to guarantee the origin of the product and to prevent potential fraud. In this work, an elemental analysis (EA) coupled with isotope ratio mass spectrometry (IRMS) was employed to identify the isotopic fingerprints of clams directly collected onsite in three Adriatic lagoons and bought at a local supermarket, where they exhibited certification.
