We present measurements of Stark interference in the 6S0 → 6P1 transition in Hg, a process whereby a static electric field E mixes magnetic dipole and electric quadrupole couplings into an electric dipole transition, leading to E-linear energy shifts similar to those produced by a permanent atomic electric dipole moment (EDM). The measured interference amplitude, aSI = (aM1 + aE2) = (5.8 ± 1.5)...

A novel, simple, sensitive and effective method has been developed for preconcentration of Hg(II) on nano-Fe3O4-DOP-ED solid-phase extraction adsorbent. In this paper, Dioctyl phthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a n...

The use of phytoremediation technology to remove heavy metal ions from aquatic environments or reduce their toxicity offers the possibility restoring ecological environment polluted water bodies. Based on available literature absorption by plants, we conducted a meta-analysis study absorptive capacities different plants as well factors that influence Hg-absorption performance. Seventeen plant f...

Mercury (Hg) pollution in the environment is a global issue and toxicity of mercury depends on its speciation. Chemical redox reactions an aquatic greatly impact Hg evasion to atmosphere methylation natural waters. Identifying abiotic pathways relevant waters important for predicting transport fate environment. The objective this review summarize current state knowledge specific at molecular le...

single and joint toxicity of chloramphenicol and hg acting on wheat (triticum aestivum l.), chinese cabbage (brassica campestris l.) and corn (zea mays l.) were investigated. the results showed positive correlations between root elongation inhibition of three plants and concentrations of pollutants added to soil (p

Mercury (Hg) transport in natural environments is of concern because Hg bioaccumulates in the food web. Particularly methyl-Hg is the form of Hg of major concern as it is highly toxic to humans and is ingested through food consumption, dominantly fish. Quantification of Hg mass loads in watersheds draining Hg mine districts allows (1) the identification of sources of contamination, (2) the eval...

Mercury (Hg) stable isotopes have been broadly used to investigate the sources, transformation and deposition of atmospheric Hg during industrial era thanks multiple isotope signatures deriving from mass-dependent (represented by δ202Hg) mass-independent fractionation ΔxxxHg) in environment. Less is known about impact past climate change on cycling, whether covary with climate. Here, we concent...
