The moons of Jupiter and Saturn, such as Europa Enceladus, are strong candidates for the search life outside Earth. Together with use direct observational methods, physical chemical processes that take place on icy may be studied planetary field analogs, is, similar reachable locations Fieldwork performed analogs can test protocols technology applied future space missions to extraterrestrial environments. Arctic is a candidate studies. This study assesses spectroscopic protocol biosignature...
Depth variations of total mercury (Hg) and methylmercury (MeHg) concentrations were obtained in cores from nonvegetated sediments, sediments colonized by Sarcocornia fruticosa, Halimione portulacoides, Spartina maritima below-ground biomass three Portuguese estuaries. Similar analyses also performed on the above-ground plant tissues. Concentrations exceeded up to 9 44 times levels sediments. Mercury MeHg 400 4700 higher than those found parts, indicating a weak upward translocation....
The saltmarsh plant Halimione portulacoides was shortly exposed to realistic levels of inorganic mercury (iHg), aiming investigate adaptative processes the roots and leaves regarding re-dox homeostasis, physiology, Hg accumulation. Plants were collected at a contaminated (CONT) reference (REF) site, addressing interference contamination background. influence major abiotic variables (i.e., temperature light) also examined. Total lev-els, antioxidant enzymes, lipid peroxidation (LPO),...
In situ air concentrations of gaseous elemental mercury (Hg(0)) and vegetation–atmosphere fluxes were quantified in both high (Cala Norte, CN) low-to-moderate (Alcochete, ALC) Hg-contaminated saltmarsh areas the Tagus estuary colonized by plant species Halimione portulacoides (Hp) Sarcocornia fruticosa (Sf). Atmospheric Hg(0) ranged between 1.08–18.15 ng m−3 CN 1.18–3.53 ALC. CN, most levels occurred during nighttime, while opposite was observed at ALC, suggesting that photoreduction not...
