Abstract:
Geochemical background - an environmental perspectiveThis article presents the concept of geochemical background from an environmental perspective. The idea of establishing the typical concentrations of elements in various environmental compartments, proposed by exploratory geochemists almost 50 years ago was important for the detection of anomalous element concentrations, thus providing a basic tool in the search for new mineral deposits. At present, the knowledge of the geochemical background of hazardous elements is essential for: defining pollution, identifying the source of contamination,

Abstract:
Resources in deserts and sandy landscapes have potential for development, but existing surveys and sampling have not collected desert soil samples. As such, the geochemical background of these spaces remains unexplored due to the vastness and desolation of deserts. Therefore, researching the geochemical background values and geochemical baseline values of deserts is of long-term significance. Our research indicates that in addition to macrostructural environmental divisions, microelement geochemistry can also be used for geological unit zoning.

Excess of arsenic in groundwater is a worldwide problem threatening the health of the millions of people directly exposed to Arsenic-rich water intake.

In Italy, arsenic is found in aquifers from north to south and it is associated to different geological settings (i.e. volcanic areas and alluvial plains).

Abstract:
Geochemical surveys on a scale of 1:200000 on the southeastern rim of the Anabar Shield revealed high-contrast extended scattering streams of titanium, iron, vanadium, niobium and other elements with the content of elements by an order of magnitude or more exceeding their content in the eluvio-deluvial formations on the banks of adjacent river slopes. In some parts of the riverbed with the length of more than 20 km, the content of titanium dioxide in bottom sediments reaches 30% with the value of geochemical background of alluvium equal to less than 1%.

Abstract:
The harvests of fruits and vegetables in the Kyustendil field have no radiation pollution. The total radiation background and abiotic environmental factors have normal values of their radioactivity. The data can be used for comparison for subsequent periods. The radioactivity of fruits and vegetables is mainly related to the total radiation background (geochemical and geophysical) and depends to a lesser extent on the radioactivity of soils. Groundwater and surface waters have an intermediate impact on agricultural production. There is no significant difference of the radiation of the studied

Abstract:
Abstract A major problem in the mature oil fields is the accompanying water production and oil production from different layers. Geochemical signals from different formations and sources can be used for identification flow profile. The study of geochemistry by area allows to establish the migration paths and movement of fluids inside the reservoir. This article focuses on the geochemical composition and isotopic geochemistry of brines and oils, as well as the metal content and the use of fingerprinting for oils (biomarker analysis). It allows to determine: the modes of development of reserves

Abstract:
Heavy minerals (HMs) are minerals with a specific gravity greater than 2.9 g/cm3. They are commonly highly resistant to physical and chemical weathering, and therefore persist in sediments as lasting indicators of the (former) presence of the rocks they formed in. The presence/absence of certain HMs, their associations with other HMs, their concentration levels, and the geochemical patterns they form in maps or 3D models can be indicative of geological processes that contributed to their formation. Furthermore trace element and isotopic analyses of HMs have been used to vector to mineralisatio

Abstract:
Regional-scale lake sediment surveys have been successfully used since the 1970s as a means for reconnaissance geochemical exploration. Lake sediment sampling is typically performed in areas with a lack of streams and an overabundance of small-sized (=5 km across) lakes. Lake sediments are known to have major, minor and trace element concentrations that reflect the local geology. Overall, lake sediment surveys are planned and conducted following four distinct stages: 1) background research, 2) orientation survey, 3) regional survey, and 4) detailed survey.
