In the European Union, nitrate vulnerable zone (NVZ) should be designed for mitigation of (NO3-) contamination caused by agricultural practices. Before establishing new NVZ, sources NO3- must recognized. A geochemical and multiple stable isotopes approach (hydrogen, oxygen, nitrogen, sulfur boron) statistical tools were applied to define characteristics groundwater (60 samples), calculate local threshold assess potential in two study areas (hereafter Northern Southern), located a...
The mechanical strength is a fundamental characteristic of rock masses that can be empirically related to number properties and the likelihood instability phenomena. Direct field acquisition information on tall cliffs, however, challenging, particularly in coastal alpine environments. Here, we propose method evaluate compressive blocks by monitoring their thermal behaviour over 24-h period infrared thermography. Using drone-mounted camera Schmidt (rebound) hammer, surveyed granitoid...
Monitoring and modelling of soil hydrological processes at large scales require measuring the spatial temporal evolution volumetric water contents, θv. Direct measurement θv can be done by sampling laboratory analyses. Although such methods are straightforward, they a lot time effort for collection several samples to account variability. Time-domain reflectometry, TDR, good alternative as it is used indirectly measure in field travel an electromagnetic pulse probe. However,...
One of the crucial challenges our time is climate change. The consequences rising sea levels and drought greatly impact water resources, potentially worsening seawater intrusion. Characterizing coastal aquifers an essential step in devising strategies to address these phenomena. Seawater intrusion poses a critical socio-economic environmental issue plain Muravera, southeastern Sardinia (Italy). This important agricultural area Sardinia, health crops compromised by increasing salinization...
Abstract The surface chemical state and composition of natural synthetic enargite samples were characterized with X‐ray photoelectron spectroscopy (XPS). Freshly cleaved, powdered ‘as received’ analysed at liquid nitrogen temperature. For the as well for binding energies Cu 2p 3/2 , As 3d 5/2 S are consistently found 932.5 ± 0.2, 43.9 0.2 162.2 eV, respectively. A second component 163.9 eV is present may be assigned to elemental sulphur. cleaved showed 43.2 161.3 respectively, . At crystals...
Radon (222Rn) and thoron (220Rn) account for almost two-thirds of the annual average radiation dose received by Irish population. A detailed study natural radioactivity levels radon exhalation rates was carried out in a legislatively designated "high radon" area, as based on existing indoor measurements. Indoor concentrations, airborne radiometric data stream sediment geochemistry were collated, set soil samples taken from area. The (E222Rn) (E220Rn) collected determined laboratory....
This review paper examines the hydrogeological characteristics and challenges of urban groundwater management in ten major Italian cities: Turin, Milano, Padova, Bologna, Roma, Pescara, Napoli, Bari, Catania, Cagliari. Urbanization has placed significant pressure on systems, highlighting need for sustainable management. The study categorizes cities based their settings uses, identifying key issues such as salinization, industrial contamination, land subsidence. findings emphasize importance...
A detailed investigation of geogenic radon potential (GRP) was carried out near Graiguenamanagh town (County Kilkenny, Ireland) by performing a spatial regression analysis on radon-related variables to evaluate the exposure people natural radiation (i.e., radon, thoron and gamma radiation). The study area includes an offshoot Caledonian Leinster Granite, which is locally intruded into Ordovician metasediments. To model release at different points, ordinary least squared (OLS) developed in...
Many countries are developing a radon action plan to provide decision-makers with reliable tool for reducing the harmful effects of exposure in dwellings and among general public and, accordingly, implement land development strategies. Mapping geogenic release different geological environments could assist delineating areas that require priority monitoring regulation, as well applying reduction techniques newly constructed buildings. In this paper, activity concentration 238U, 226Ra, 232Th...
