AbstractEnvironmental pollution is serious problem all around the world. Over the past decades, several well-known heavy metals have received much attention of researchers, and new information has been collected on their toxicity. However, knowledge of environmental chemistry of many other potentially toxic trace elements is scarce, though it is kn...

Phytoextraction using hyperaccumulating plants is a method for the remediation of soils contaminated with trace elements (TEs). As a strategy for improvement, the concept of fungal-assisted phytoextraction has emerged in the last decade. However, the role played by fungal endophytes of hyperaccumulating plants in phytoextraction is poorly studied. ...

The presence and composition of ash in solid waste streams produced by the thermochemical processes can affect the further disposal or use of the waste. This study characterised the chemical species, mineralogy and trace element mobilisation in laboratory-produced ashes arising from different municipal solid waste (MSW) streams processed under redu...
Mercury (Hg) concentrations have significantly increased in oceans during the last century. This element accumulates in marine fauna and can reach toxic levels. Seafood consumption is the main pathway of methylmercury (MeHg) toxicity in humans. Here, we analyzed total Hg (T-Hg) concentrations in two oceanic squid species (Ommastrephes bartramii and...

The present study emphasises occurrence, mineral assemblages and mineral chemistry of the Neoproterozoic Degana Peraluminous Granite (DPG) around Rewat Hill and its fertility. Based on field evidences and nature of occurrences of wolframite, the tungsten mineralization of the Rewat Hill has been classified into five types; Type-I: quartz–wolframite...

Scleractinian corals typically form a robust calcium carbonate skeleton beneath their living tissue. This skeleton, through its trace element composition and isotope ratios, may record environmental conditions of water surrounding the coral animal. While bulk unrecrystallized aragonite coral skeletons can be used to reconstruct past ocean condition...

AbstractThe composition of resins of seven ancient Egyptian mummies from the collection of the Pushkin State Museum of Fine Arts was studied. n-Alkanes were found in the resins by gas chromatography–mass spectrometry, which suggests the presence of natural bitumen in these resins. By comparing the hydrocarbon profiles of the studied mummies with th...

Coral skeletons are one of the best archives for past ocean seawater (SW) chemistry and isotopes. However, the distribution coefficients of major and minor elements in coral skeletons are not well determined. In this study, we launched an experiment to determine the distribution coefficients of multiple elements in corals’ skeletons by changing Ca ...

Background: It is known that some elements are needed for normal thyroid gland functions. Iodine and selenium are the most well-known trace elements necessary for thyroid metabolism. Selenium is involved in the formation of thyroid hormones and the structure of the deiodinases associated with the development of the thyroid gland. While the role of ...

Analyzing the presence and quantifying trace elements is of paramount importance to understand natural environmental processes and monitor the degree of anthropogenic disturbance to mitigate impacts already caused. Here, we aimed to establish a baseline of the trace elements profile and concentrations in sandy sediments of intertidal areas of three...
