We report on integrated geomorphological, mineralogical, geochemical and biological investigations of the hydrothermal vent field located floor density-stratified acidic (pH ~ 5) crater Kolumbo shallow-submarine arc-volcano, near Santorini. features rare geodynamic setting at convergent boundaries, where arc-volcanism seafloor activity are occurring in thinned continental crust. Special focus is given to unique enrichments polymetallic spires Sb Tl (±Hg, As, Au, Ag, Zn) indicating a new...
People spend increasing amounts of time at home, yet the indoor home environment remains understudied in terms potential exposure to toxic trace metals. We evaluated metal (and metalloid) concentrations (As, Cu, Cr, Mn, Ni, Pb, and Zn) health risks dust from homes 35 countries, along with a suite potentially contributory residential characteristics. The objective was determine source inputs conditions associated risk across range international communities. For all enrichments compared global...
The performance of the Spectrace TN 9000 portable X-ray fluorescence (P-XRF) instrument for in situ sampling and analysis contaminated soil was evaluated. method compared with laboratory samples using ICP-AES XRF as established methods assessment land. trueness field-based P-XRF results affected by moisture surface roughness samples, after correction which, no bias observed between analytical comparative methods. Relatively large measurement uncertainty (±55% Pb) caused small sample mass...
Abstract The Lavrion carbonate‐hosted Pb‐Ag‐Zn deposit in southeast Attica, Greece, consisted of significant non‐sulfide ore bodies. polymetallic sulfide mineralization was subjected to supergene oxidation, giving rise gossan. principal minerals past economic importance were smithsonite, goethite and hematite. mineral assemblages occupy secondary open spaces occur as replacement pods within marble. Calamine iron mainly filled fractures. X‐ray diffraction scanning electron microscopy samples...
Soil contamination is a persistent problem in the world. The redevelopment of site with historical deposition metals might conceal threat remaining pollution, especially when has become public place. In this study, human health risk assessment performed after defining concentrations Pb, Ni, and Zn topsoil former shooting range rehabilitated into park Municipality Kesariani (Athens, Greece). A methodology that uses inductively coupled plasma mass spectrometry (ICP-MS, 13 samples), another...
Abstract Protection against arsenic damage in organisms positioned deep the tree of life points to early evolutionary sensitization. Here, marine sedimentary records reveal a Proterozoic concentration patterned glacial-interglacial ages. The low glacial and high interglacial concentrations, suggest deteriorating habitable conditions may have coincided with atmospheric oxygen decline after ~2.1 billion years ago. A similar intensification near continental margin levels Cryogenian glaciations...
Our indoor microbiome consists of a wide range microbial taxa. Whilst many these microbes are benign, some beneficial, harmful, yet our knowledge the spatial heterogeneity bacterial assemblages in residential environment remains limited. To investigate existence common core house dust we selected household vacuum dusts, collected through citizen science approach, from homes across two bioclimatic regions (UK, Oceanic/Maritime and Greece, Mediterranean). Following extraction DNA each sample,...
Abstract Natural CO 2 releases from shallow marine hydrothermal vents are assumed to mix into the water column and not accumulate stratified seafloor pools. We present newly discovered subsea pools located within Santorini volcanic caldera of Southern Aegean Sea, Greece, that emissions geologic reservoirs. This type pool, containing highly concentrated , provides direct evidence benthic accumulations originating sub-seafloor releases. Samples taken these acidic devoid calcifying organisms...
