Trace elements in soils of the Antarctic ice-free areas: Insights on natural ge...

Climate change is transforming the ice-free areas of Antarctica, leading to rapid changes in terrestrial ecosystems. These areas represent <0.5% of the continent and coincide with the most anthropogenically pressured sites, where the human footprint is a source of contamination. Simultaneously, these are the locations where permafrost can be found, not being clear what might be the consequences following its de...

Looking at the potential of marine macroalgae supplementation to afford neuropr...

Background: Marine macroalgae have potential as a source of many natural compounds with health benefits [1], but their use to mitigate aquatic contaminants bioaccumulation in fish and resultant toxicity is an underexplored research topic. Objective: Asses if a marine macroalgae-enriched diet can provide neuroprotection Diplodus sargus when exposed to waterborne inorganic mercury (iHg), namely by reducing bioacc...

Redox homeostasis disclosed in the saltmarsh plant Halimione portulacoides upon...

The saltmarsh plant Halimione portulacoides was shortly exposed to realistic levels of inorganic mercury (iHg) with the aim of investigating the adaptative processes of the roots and leaves regarding redox homeostasis, physiology, and Hg accumulation. Plants were collected at a contaminated (CONT) and a reference (REF) site to address the interference of contamination backgrounds. The influence of major abiotic...

Mercury mobility and effects in the salt-marsh plant Halimione portulacoides: u...

The plant Halimione portulacoides, an abundant species widely distributed in temperate salt-marshes, has been previously assessed as bioindicator and biomonitor of mercury contamination in these ecosystems. The present study aims to assess uptake and distribution of total mercury (THg) and methylmercury (MMHg) within H. portulacoides, potential mercury release by volatilization through leaves, and toxicity and ...

Evaluation of the potential of the common cockle (cerastoderma edule l.) for th...

Common cockles (Cerastoderma edule, L. 1758, Bivalvia: Cardiidae) were subjected to a laboratory assay with sediments collected from distinct sites of the Sado Estuary (Portugal). Cockles were obtained from a mariculture site of the Sado Estuary and exposed through 28-day, semi-static, assays to sediments collected from three sites of the estuary. Sediments from these sites revealed different physico-chemical p...
