Abstract Geochemical analysis of Potentially Toxic Elements (PTEs) in stream sediments is essential for understanding environmental impacts areas with complex geology and mining activities. This study focuses on from the eastern sector Mt. Amiata Hg-district (central Italy) to define background values As, Sb, Cr, V, Co, Cu, Ni, Hg, latter being speciated assess its bioavailability mobility potential risks. The are divided into four different groups: (1) Volcanic, (2) Volcanic-dominated, (3)...
Background and geochemical baseline values of Potentially Toxic Elements (PTEs) in soils developed on natural or anthropogenically-affected areas are increasingly important parameters as they represent highly useful tools at local, regional, national European level. While background mostly applied to uncontaminated verify the presence high anomalous concentrations PTEs due geogenic sources, better representing those where anthropogenic activities have altered more less significantly values....
Thermal desorption is a well-assessed technique to speciate mercury (Hg) in soils and sediments. However, the effects related different matrices are still not properly assessed. In this study, thermal was applied Hg-free calcite mixed with Hg standard rich carbonate silicate minerals, as well organic matter.
The distribution of heavy metals in plants (Castanea sativa, Sambucus nigra, Verbascum thapsus, Popolus spp., Salix Acer pseudoplatanus, Robinia pseudoacacia) growing soils from active and abandoned mining areas is scientific significance as it allows to recognize their ability survive a hostile environment provide useful indications for phytoremediation operations. In this work, the former Hg-mining area Abbadia San Salvatore (Tuscany, Central Italy) were analyzed total, leached Hg, %...
The Galleria Italia waters drain the complex tunnel system of former Hg-mining area Abbadia San Salvatore (Tuscany, central Italia) and feed 2.5 km-long Fosso della Chiusa creek. mining exploitation was active for more than one century 100,000 tons liquid mercury were produced by roasting processes cinnabar (HgS). In this work, a discontinuous geochemical monitoring circumneutral carried out from February 2009 to October 2020, during which main physicochemical parameters, minor dissolved...
Total and leached Arsenic, Mercury Antimony were determined in the topsoils developed on mining waste dumping area of Le Lame (Mt. Amiata, central Italy) where post-processing Hg-rich ore deposits from Abbadia San Salvatore stored. The concentrations As, Hg Sb up to 610, 1910 1610 mg kg−1, respectively, while those leachates (carried out with CO2-saturated MilliQ water simulate meteoric conditions) 102, 7 661 μg·L−1, respectively. Most aqueous solutions characterized by content <0.1...
Since February 2013, 21 periodical samples (mostly carried out seasonally) of ground and surface waters within outside the former Hg-mine Abbadia San Salvatore (Tuscany, central Italy) have been analyzed for main composition, Hg, As, Sb, and, in most cases, &#160;selected trace elements. The groundwater refer to a phreatic aquifer at depths between 5 10 m, characterized by low transmissivity whose are interacting with terrains containing tailings derived from production liquid mercury...
Since 2013, 34 surveys of surface and ground waters within outside the former Hg-mine Abbadia San Salvatore (Italy), which is currently under remediation, were performed for determining Hg, As, Sb, main minor solutes. The water quality rather poor since most show relatively high Hg concentrations (up to 695 µg/L). Differently, As Sb only overcome Italian law thresholds in a few sites. A geochemical variability was observed groundwaters without any clear relationship between wet dry periods....
The distribution of heavy metals in plants growing soils from active and abandoned mining areas is scientific significance as it allows one to recognize their ability survive a hostile environment provide useful indications for phytoremediation operations. In this work, developed the former Hg-mining area Abbadia San Salvatore (Tuscany, Central Italy) were analyzed total, leached Hg, % organic- inorganic-related Hg. dehydrogenase enzyme activity (DHA) was also measured with aim evaluate...
The chemical composition of volatile organic compounds (VOCs) in interstitial soil gases from hydrothermal areas is commonly shaped by both deep conditions (e.g., temperature, redox, sulfur fugacity) and shallow secondary processes occurring near the soil-atmosphere interface. Caldara di Manziana Solfatara Nepi, i.e., two systems characterized diverse physicochemical located Sabatini Volcanic District Vicano-Cimino District, respectively (Central Italy), were investigated to evaluate...
<abstract> <p>The environmental impact of mining and smelting in the world-class Monte Amiata mercury (Hg) ore field has long been studied, before after final closure 1982. A first summary was presented 2015. With this contribution, we review studies conducted last eight years. The most significant results include ⅰ) Hg-isotope characterization primary (cinnabar), waste (calcines), soil, fish stream sediments; ⅱ) analysis interplay between geomorphological evolution, fluvial...
The occurrence of gaseous mercury pollution has to be identified and monitored through innovative methods techniques, which would serve as a step toward strengthening the knowledge mechanisms dispersion in atmosphere, accordance with provisions Minamata Convention on Mercury. Consequently, aim this work is present very first data obtained by directly continuously measuring GEM (Mercury Elemental Gas) lower atmosphere an original assembly UAV (Unmanned Aerial Vehicle, heavy-lift octocopter)...
Mine dumps are man-made geological formations characterized by unique chemical, particle-size, bacterial, and physical mechanical features, representing deposits or cumuli of crushed, grounded roasted material. Processing plants metallic poli-sulfide ore have contributed to pollute soils surface ground waters in many areas worldwide. The southern sector the Apuan Alps (northern Tuscany, Italy) hosts a number small pyrite &#177; barite iron-oxide orebodies that been exploited since at...
KEU (Kraftanlagen Energie und Umwelttechnick) is a by-product of pyrolyzed waste sewage sludge produced by wastewater treatment from tannery industries. regarded as an industrial non-hazardous after inertization to obtain sintering granulate and usually mixed with demolition-construction or mud products produce EoW (End Waste) material. However, the resulting materials are apparently responsible anomalous concentrations Cr CrVI other PTEs (Potentially Toxic Elements), recovered in several...
Active biomonitoring of mercury (Hg) using non-indigenous moss bags was performed for the first time within and around former Hg mining area Abbadia San Salvatore (Mt. Amiata, central Italy). The purpose to discern spatial distribution, identify most polluted areas, evaluate impacts dry wet deposition on mosses. exposed consisted a mixture Sphagnum fuscum tenellum from an external uncontaminated area. In each site, two different types bags, one uncovered (to account + deposition) covered...
Determining the background values of chemical components in environmental matrices is a difficult task. This particularly true regions where human impact due to industrial, mining, agricultural and urban activities coexists with geological (geogenic) anomaly, which influences concentration certain elements soils, waters air. In these cases, term geochemical baseline (GB) preferable, since it considers actual content that element superficial environment at given point time, including both...
