Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form is important to industry. The primary use of metallic arsenic is in alloys of lead (for …

Arsenic (33 As) has 33 known isotopes and at least 10 isomers. Only one of these isotopes, 75 As, is stable; as such, it is considered a monoisotopic element. The longest-lived radioisotope is 73 As has a half-life of 80 days.

A 68-year-old man with pancytopenia due to myelodysplastic syndrome was given arsenic trioxide and 8 weeks later developed a chronic non-productive cough, weight loss, and dyspnea on exertion. He had bilateral crackles over the lower two-thirds of the lungs, mild pitting edema in both legs, and multiple petechiae diffusely scattered over the ...

Arsenic derived from natural sources occurs in groundwater in many countries, affecting the health of millions of people. The combined effects of As(V) reduction and diagenesis of iron oxide minerals on arsenic mobility are investigated in this study by comparing As(V) and As(III) sorption onto amorphous iron oxide (HFO), goethite, and magnetite at …

3 Arsenic Toxicity. Arsenic compounds are known to be very toxic and carcinogenic. Chronic exposure to arsenic has more effects on health than any other toxicant, and the list continues to grow.

A total of 43 of 68 patients in the ATRA–arsenic trioxide group (63%) and 4 of 69 patients in the ATRA–chemotherapy group (6%) had grade 3 or 4 hepatic toxic effects during induction or consolidation therapy (for patients in the two groups) or during maintenance therapy (for patients in the ATRA–chemotherapy group) (P<0.001). In all cases, the …

Orphan Metals Arsenic The Arsenic Consortium was founded by 7 companies in 2009 for one aim: jointly fulfilling the requirements laid down by the EU REACH Regulation.

Arsenic is a metalloid, that is, considered to be a human carcinogen. Millions of individuals worldwide are chronically exposed through drinking water, with consequences ranging from acute toxicities to development of malignancies, such as skin and lung cancer. Despite well-known arsenic-related health effects, the molecular mechanisms involved are not fully understood; however, the arsenic ...

Arsenic Cleanup Criteria for Soils in the US and Abroad 95 1. INTRODUCTION Over the past few decades, arsenic has been increasingly examined and analyzed

They found that the wine with the highest arsenic level contained 68.4 ppb. The overall mean concentration for all wines tested was 12.5 ppb. The wines named in the suit contained a mean of 25.6 ppb compared to 7.42 ppb for the randomly purchased wines. They found that cheaper wines generally contained higher levels.

FOREWORD . The purpose of this report is to provide a synopsis of the availability, performance, and cost of 13 arsenic treatment technologies for soil, water, and waste.
