For thallium, these temperatures were 900 °C and 1700 °C, and the determinations were made without a modifier. For chromium, the limit of detection (LoD) for LS-GF AAS and HR-CS GF AAS were 150 ng g − 1 and 60 ng g −1, respectively. For thallium the LoD were 15 ng g −1 for LS-GF AAS and 3 ng g −1 using HR-CS GF AAS. …

The most characteristic symptom of thallium exposure is alopecia (loss of hair). Cutaneous effects may include dry, scaly skin and impairment of nail growth often resulting in the appearance of crescent-shaped strips across fingernails and toenails (Mees' line). Other symptoms in acute poisoning relate chiefly to the gastrointestinal tract ...

Chromium (atomic symbol: Cr, atomic number: 24) is a Block D, Group 6, Period 4 element with an atomic weight of 51.9961. The number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron configuration is [Ar] 3d 5 4s 1. Louis Nicolas Vauquelin first discovered chromium in 1797 and first isolated it the following year.

Chromium (Cr) liver injury strongly depended on its oxidation state with Cr 6+, syn hexavalent chromium or Cr(VI), and Cr 5+ as the most toxic species . Inside the hepatocytes, Cr 6+ is reduced through various reduction pathways to stable Cr 3+ and to Cr 5+, which by itself forms a new Cr 5+ complex, Cr 5+ –BT 2−, a stable compound that ...

6. Application of Chromium, Arsenic, Antimony, and Thallium Speciation Analyses in Bottom Sediment Samples. The high chromium content in bottom sediments is often caused by the close vicinity of tanneries, steelworks, or galvanic shops. The tanning industry is a typical source of Cr(III), including mainly sulphates . Under the redox and ...

Experimental liver injury with hepatocelluar necrosis and abnormal liver tests is caused by exposure to heavy metals (HMs) like aluminum, arsenic, beryllium, cadmium, chromium, cobalt, copper, iron, lead, mercury, molybdenum, nickel, platinum, thallium, titanium, vanadium, and zinc. As pollutants, HMs disturb the ecosystem, and as these ...

The structure and magnetic properties of TlCrX 2 (X= S, Se, Te), Tl 3 CrS 3, Tl 3 Cr 3 S 5, TlCr 3 S 5, TlCl 5 S 8 and AgCrO 2 have been investigated. TlCrS 2, TlCrSe 2 and Tl 3 CrS 3 order ferromagnetically with Curie temperatures in the range 60–140 K. The other compounds are antiferromagnetics with negative paramagnetic Curie …

Abstract. A variety of trace elements are contained in coal, including the environmentally sensitive elements thallium, cadmium, chromium, and vanadium; such …

The sequential voltammetric determination of chromium, thallium, cadmium, lead, copper and antimony in dialysate concentrates (DCs), is presented herein. Chromium was quantified by adsorptive ...

Chromium compounds are used as industrial catalysts and pigments (in bright green, yellow, red and orange colours). Rubies get their red colour from chromium, and glass treated with chromium has an emerald green colour. Biological role. Chromium is an essential trace element for humans because it helps us to use glucose.

A variety of trace elements are contained in coal, including the environmentally sensitive elements thallium, cadmium, chromium, and vanadium; such elements can be transferred to the environment easily within smoke and ash released by burning coal, causing adverse environmental effects. In the present study, the migration …

Thallium-201 is a radiopharmaceutical agent used in the diagnosis of coronary artery disease and parathyroid hyperactivity. Other useful applications for a thallium-201 scan, like tumor diagnosis and olfacto-scintigraphy, are being explored and have shown promising results in various studies. This activity reviews the indications, …

Valences of the Elements Chemistry Table. You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less …
