knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. the method, however, presents some deficiencies, including labor-intensive proced...

The concentration of trace toxic metals (Cr, Zn, As, Pb, Cd, Cu, and Ni) in soil rice plants, including the stems, leaves, grain, from main rice-producing provinces Ecuador, was determined. Additionally, soils were analyzed to determine their properties, composition, total content, bioavailable fraction, geochemical fractions elements. Approximately 30% samples case Cr Cu 10% Ni exceeded legal ...

Phytoremediation is an effective and low-cost method for the remediation of soil contaminated by potentially toxic elements (metals metalloids) with hyperaccumulating plants. This study analyzed hyperaccumulator publications using data from Web Science Core Collection (WoSCC) (1992–2020). We explored research status on this topic creating a series scientific maps VOSviewer, HistCite Pro, CiteSp...

Considered were four dairy farms. Two were certified organic farms and two were conventional – one with intensive and one with extensive production system. Observations were conducted on 10 Holstein-Friesian (HF) cows from each farm while from conventional farm with extensive production additional 10 Polish Red (PR) cows were observed. Samples of milk and hair for determination of minerals were...

Detailed chemical composition of the open cluster IC 4651: The iron peak, α elements, and Li. Abstract. We present a detailed chemical analysis of 22 stars along the colour-magnitude sequence of the intermediate-age (1.7 Gyr) open cluster IC 4651, based on high-resolution, high S/N ratio spectra from UVES/VLT. IC 4651 thus becomes one of the few open clusters for which a detailed composition an...

Non-conventional stable isotopes have received increasing attention in the past decade to investigate multi-level ecological connections from individuals ecosystems. More recently, trace and non-nutrient elements, potentially toxic (i.e., Hg), also been recognized of great significance discriminate sources, transports, bioaccumulation, as well trophic transfers. In contrast, lithium (Li) concen...

The occurrence of potentially toxic elements (PTEs, including As, Cd, Hg and Pb) both anthropogenic natural origin in the environment represents an issue global concern, leading to a general decline environmental quality continental aquatic systems [...]

The primary objective of the current study was the investigation of the influence of zinc asparaginate supplementation for 7 and 14 days on toxic metal and metalloid content in rat organs and tissues. Rats obtained zinc asparaginate in doses of 5 and 15 mg/kg/day for 7 and 14 days. At the end of the experiment rat tissues and organs (liver, kidney, heart, m. gastrocnemius, serum, and hair) were...
