Arsenic

Although arsenic is mostly known for its poison, the lesser known about is its curative aspects. Before the introduction of penicillin, arsenic was used in the treatment of syphilis. However, today arsenic has been replaced by sulfa drugs and antibiotics. Recently, there has been a few studies researching the curative effect of arsenic. Previously in Shanghai, China, a group of researchers had discovered a remedy for acute promyelocytic leukemia (APL) which is a very lethal. They discovered that

Thesis statement: Water, food, and air that contains arsenic causes human health problems. Background and history of Arsenic? The elemental Arsenic was discovered by Albert Magnus in 1250 A.D. The word “Arsenic” comes from a Greek word “Arsenikon,” means “yellow orpiment.” Arsenic has an atomic number of 33 with a melting point of 1141 degrees Fahrenheit or 889 Kelvin. The density is 5.75 g cm-3 and the atomic mass is 74.922 g/mol. Arsenic was already known for a long time during the Egyptian,

Introduction Inorganic arsenic, which is often metabolised in humans into toxic methylated arsenicals, is known to be a potential carcinogen that causes tumours of the lungs, skin, urinary bladder, and other non-cancer effects (Radosavljevic & Jakovljevic, 2008). Arsenic is a significant contaminant and its organic and inorganic occurrence in the environment results from both natural and anthropogenic activities. Humans are mainly exposed to the organic forms - arsenite, AsO33-, and arsenate, AsO43-

4U1b C. Cerra 20 November 2016 Arsenic; a Metabolic Toxin Arsenic (As) is a metalloid in group 15, period 4 of the periodic table. It is associated with the atomic number 33 and maintains an atomic weight of 74.92 (Gagnon). As a solid at room temperature, it is most likely to be found as a shiny grey element; however, it may also appear as yellow or black. It is also known to be quite brittle in its solid state (PubChem). There are three different categories that arsenic compounds may be identified

a. Inorganic arsenic is highly toxic and a significant public health threat throughout the world. Long-term exposure to arsenic through contaminated water can lead to arsenic poisoning and a variety of adverse health effects, including skin lesions, cancer, and respiratory and cardiovascular conditions. However, arsenic is highly abundant in the Earth’s crust and is naturally present across the world in the air, water, and soil. Arsenic integrates into the environment with natural processes including

Analysis of Arsenic in Drinking Water Analysis: Trends Arsenic is well known for its dangerous toxic features it brings to humans and the environment. But, it was not until the late 1980’s did scientists and public health officials realized that even at low doses of ingestion, arsenic is very dangerous and can cause serious health effects (Bolt, 2013). Till this day arsenic continues to be a huge public health issue, not only in parts of the United States but in developing countries worldwide (Bolt

Arsenic is a metalloid obtained by Albertus Magnus, a German alchemist. Magnus obtained this by heating soap together with orpiment. Arsenic is used as insecticides and wood preservatives. Today, arsenic in insecticides are restricted due to the FDA. Arsenic is also a cure for humans but it is also deadly. There are two forms of arsenic; inorganic and organic. Inorganic is considered poisonous and organic is considered nontoxic to humans. Inorganic arsenic is formed by the arsenic atoms combining

What is Arsenic? Arsenic with the symbol As is a metalloid that means it has properties from both metals and nonmetals. It is a natural component of the earth’s crust and you can find it in its gray, yellow and black form. In the environment it forms organic and inorganic chemical compounds as a result of natural and anthropogenic activities. A worldwide phenomenon (magnitude of the problem)( A worldwide impact) Poisoning from arsenic is not a threat that belongs to the past and it should not be

Introduction Arsenic, also known by its chemical signature As, is one of the naturally occurring elements on the planet. It can be found in food, soil, air, and in the water. Moreover, due to the wide distribution of it on the planet, everyone interacts with it in one form or another. It was discovered in 1250 by Albertus Magnus, arsenic has been used in a variety of manners in many early historical civilizations such as the Greek and Chinese. Magnus was said to have derived the compound from heating
