Abstract Methylmercury is a potent toxin threatening the global population mainly through consumption of marine fish. Hydrothermal venting directly delivers natural mercury to ocean, yet its flux remains poorly constrained. To determine extent which anthropogenic inputs have increased oceanic levels, it crucial estimate levels. Here we combine observations vent fluids, plume waters, seawater and rock samples quantify release from Trans-Atlantic Geotraverse hydrothermal at Mid-Atlantic Ridge....
The origin of the bioaccumulative neurotoxin methylmercury (MeHg) in ocean remains elusive. current paradigm suggests that microbial methylation inorganic Hg within oceanic water column produces monomethylmercury (MMHg) and potentially dimethylmercury (DMHg). Reaction rates main drivers governing MeHg levels (sum MMHg DMHg) are poorly constrained. We conducted ambient species measurements enriched isotopic tracer experiments waters two contrasting marine environments, oligotrophic...
Abstract A prominent feature of the cumulate rocks Nova intrusions is presence reaction coronas between olivine and plagioclase. particular spatial arrangement mineral textures, typical olivine–plagioclase in high-P troctolites gabbros worldwide, almost universally observed: partially resorbed with a cuspate margin, surrounded by orthopyroxene, zone symplectite comprising hornblende + clinopyroxene, orthopyroxene Cr-poor Al–(Fe, Mg) spinel, boundary against Where amphibole-free...
The UNEP Minamata Convention on Mercury aims to reduce human exposure toxic mercury through the reduction of anthropogenic emissions. We are primarily exposed via consumption fish that bioaccumulate from ocean. current paradigm is emissions (present-day 3,100 tons per year) have increased global oceanic reservoir by 21%. This estimate flawed because we do not know how much natural resided in ocean before started. similarly unable quantify affected levels. Hydrothermal venting only direct...
Panarea, an island in the Tyrrhenian Sea, Mediterranean is distinguished for its hydrothermal vent ecosystems that substantially influence local biodiversity. While vents are recognised their mineral-rich composition, potential release of mercury (Hg), a non-essential metal, into surrounding environment raises environmental concerns. This study investigates oxidative stress status and cellular energy allocation autochthonous marine gastropod Phorcus turbinatus (Born, 1778), collected from...
