Arsenic
Element 33: Arsenic
Abstract
Arsenic is element 33 on the periodic table and is in Group 15. Arsenic is obviously an extremely poisonous element; however, some people have found arsenic to have a restorative effect on them. Chemically, arsenic is a metalloid. Two common forms of arsenic are gray and yellow. (see Figure 1-A) Element 33 has an atomic weight of 74.9216 and the chemical symbol of As. It boils at 613ºC, melts at 817ºC, and has a density of 5.72. (see Figure 2-A) The element has been known for centuries and can be easily obtained from ores such as arsenopyrite (FeAsS), realgar (As2S2), orpiment (As2S3), and arsenic trioxide (As2O3). There are many uses for arsenic. Among them is in the manufacturing of glass to eliminate the air bubbles and the green color caused by contaminated iron compounds. Arsenic is also added to materials such as lead and copper alloys to increase the strength and better the corrosion resistance. Although it is well known that arsenic is often used in tales (both true and otherwise) as a killing agent, arsenic has been used as a curative as well. Before penicillin was introduced, arsenic played a significant role in the treatment of syphilis. Other good uses for element 33 are as insecticides and semiconductors. Gallium arsenide (GaAs) is a known semiconductor that is also used as a laser material. A good test for the detection of arsenic is the Marsh test, invented by James Marsh, an English chemist.
Introduction
Arsenic is a rather notorious element. Mystery lovers know it as the poison and in the past, it has been one of the favored choices of criminals. (Bodin and Cheinisse 1970) Arsenic compounds have been known in the world since the 4th century BC...

In chapter 8 titled "Radium (Ra)" of The Poisoner's Handbook by Deborah Blum, the most interesting story developed within this chapter was the death of dial workers at Orange, New Jersey after been exposed to radium every day. It was interesting due to the fact that radium was used everywhere in the community and was never thought it could harm anyone. Radium was a super element that was used everywhere, but its continuous use unmasked its fatal habits. As it was stated in the text, "Radiant health, the ads proclaimed-beautiful skin, endless vigor, and eternal health—ingesting radium seemed the next best thing to drinking sunlight." (Blum 179). People were accepting radium as a natural gold element but they haven't realized constant contact

The author states “the effort to suppress scientific information reflects a dangerously outdated attitude.” Donahue supports this claim by explaining several cases in science where sharing information on microbiological studies has helped science move forward. The author mentions an article that was published describing how susceptible the United States milk supply is to the botulinum toxin. This article was suspended by the National Academy of Science because they believed it to be a “road map for terrorists” (p. 1). The author believes, however, that instead of censoring such an article, this information should be shared, this way other scientists will be able to discover ways to defend against terrorist attacks.

Toxicology is the investigation of the unfavourable impacts of chemicals on living creatures. Forensic toxicology takes it above and beyond, including various related controls to aid in the location and elucidation of pills and harms poisons and drugs in medico legitimate passing examinations, human execution issues; e.g.,
