Arsenic As A Natural Component Of The Earth 's Crust And You Can Find It

With all the contaminations of our drinking water people are greatly affected on a daily basis. People expose to a lot of diseases such as cholera, stomach viruses and this severe cases this can even lead to death. The death rates in developing counties are at its highest right now. Human are not only the ones affected animals also suffer the consequences of our ignorance example a herbicide call Atrazina which is use to kill weeds is said to be found most in or drinking water, streams and rivers is said to be responsible for the low sperm count in animals, such as fish and frogs, often times become cross gender and in most cases may result into death. Studies have also

While nitrates are one of the major contaminants in the area, San Joaquin Valley residents face drinking water pollution from many other sources including arsenic, coliform bacteria, and pesticides. Arsenic is a naturally occurring semi-metal element that is found in different types of rocks. While arsenic primarily occurs naturally, human activities impact the amount of arsenic in groundwater. Arsenic is not only toxic at high concentrations, but also harmful after prolonged exposure at moderately elevated levels. California recognizes arsenic as a human carcinogen and believes prolonged exposure to the element to be associated with various cancers, including skin, bladder, kidney, lung, and liver cancers. A study in Maine found a connection between water contaminated

The German alchemist, Albertus Magnus from the 13th century, is the man who is known for first identifying Arsenic. Being number 33 on the periodic table, arsenic falls inside the metalloid line because of its characteristics. According to the Green Facts website “Arsenic is a naturally occurring element that can be found in the Earth crust.” (Arsenic n.d.) It

It is often believed that unsafe drinking water is strictly a critical health issue in impoverished third world countries. However, in recent years in the United States, one of the most developed countries in the world, we are experiencing multiple incidences of widespread public water contamination. In 2014, news stations across America were flooded with the devastating water crisis in Flint, Michigan and though this is the most recent occurrence, it is not an isolated incident. Though Flint was the most widely recognized incident, in the same year two other distressing cases of unsafe tap water also occurred in two other United States cities. While several of these cases of water contamination in the U.S. have been unintentional, other

There is a higher likelihood of being exposed to arsenic via food ingestion compared to inhaling arsenic-contaminated air or drinking arsenic-contaminated water. Once the arsenic has been absorbed through the lungs or gastrointestinal tract, the arsenic is distributed through the body via the bloodstream. For metabolism, in the blood stream, the arsenic becomes attached to the red cells, white cells, and cells that can convert arsenate to arsenite. Some of those arsenites are taken to the liver, where they are methylated by the enzymatic transfer of the methyl group from S-adenosylmethionine (SAM) and the arsenite are converted into methyl arsonate (MMA V) and dimethyl arsenate (DMA V). Those metabolites, methyl arsonate and dimethyl arsenate, are then ready to be excreted. If the liver is at its limit of methylation, excess arsenites are stored in the body’s soft tissues. Arsenic and its many variations (ie. MMA V, DMA V, arsenate, and arsenite) are excreted through the kidneys. There is a possibility that two to four weeks after being exposed to arsenic, some of the arsenic can still be found in the human’s hair, nails, skin, and bones and teeth (ATSDR,

Arsenic has an atomic number of 33 and a relative atomic mass of 74.922amu. Arsenic is an odd element, as it acts like metal even though it is a natural element. Arsenic is found in natural environments, and in limited quantities found in rocks, soil, water and more. Arsenic was very known to the ancient Egyptians and the Chinese, they used Arsenic as a way of gilding metals. The orpiment(As2S3) and the realgar (As4S4) : are the two Arsenic sulphide minerals that Greek Philosopher, Theophrastus. As2O3 is the trioxide, is one of the end products of copper refining. This is a form of arsenic that has also been known for awhile now, and it is called white arsenic. The official discovery of arsenic is to Alberts Magnus in around the 1200s. As to the physical property, it is radiant, has a silver colour and fragile, as it is a semi-metal. When in exposed to air, it is rapidly damaged, because of the usual elements in air, such as nitrogen and more. Arsenic is not particularly used in any technology, but recently we use Arsenic in semiconductor gallium arsenide, it can convert electric currents to laser lights. Usually it is not used

Trivalent (arsenite) and pentavalent (arsenate) arsenic produce different effects on cells, yet there is little distinction between the two forms of arsenic when discussing signs and symptoms of poisoning. An important fact to note is that during the metabolism of arsenate, 50-70% of it will be reduced to arsenite in the first step of the process. Therefore, the differences in the cell effects are seen from the 30-50% of the pentavalent arsenic unchanged via the bioactivation step of oxidizing glutathione or enzymatically catalyzed by arsenate reductase.1,2

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 as: Inorganic Arsenic compounds (i.e., arsenic trioxide (As2O3), and lead arsenate (PbHAsO4) are some of the more common ones), Organic Arsenic compounds (i.e., Arsanilic Acid (C6H8AsNO3), and Methylarsonic Acid (CH5AsO3) are the more common ones), and Arsine gas (AsH3) (NCBI). All of the aforementioned states, categories, and compounds have various toxicities- the most toxic and severe symptoms tend to result for the entrance of inorganic arsenic and arsine gas into the body.

Do you feel that your chemical should be more tightly regulated in the United States? Why or why

Arsenic is an invisible killer that many people may be drinking as I write this article. It was such a problem for the United States, that in 2001, the US Environmental Protection Agency had to lower the maximum level of arsenic allowed in drinking water from 50 micrograms per liter (ug/L) to 10 micrograms per liter (ug/Liter) (Ryker, 2001). Despite this change in policy, this issue of arsenic contamination continues, and is even more widespread in many more places outside of the United States. Unlike the U.S., underdeveloped countries like India, Cambodia, and Bangladesh cannot rely on the usual testing’s more developed countries are accustomed to. For example, a study in Bangladesh (2009) showed 13% (1,883) of their findings (14,492 samples) had an arsenic concentration that exceeded 50 ug/Liters (Rodrigues et al, 2016). The old maximum stated by EPA back in 2001. Information like this is then used, in hopes that it creates more of an importance

Additionally, it has been proven that when ingested; arsenic can lead to invasive squamous cell carcinoma, Bowen illness, basal cell skin carcinoma, and liver, kidney, lung, and bladder

The arsenic contaminated water should not be used for drinking. Hospitalization with good nutritional diet reduces the primary symptoms. A high protein diet in food helps in clearance of inorganic arsenic by the process of methylation. Supplemental potassium decreases the risk of experiencing a life threatening heart rhythm problem from arsenic trioxide. The patients should be treated clinically based upon the symptoms. Bronchial irritation must be stopped to prevent arsenic induced bronchitis. Hence the smokers must be motivated to quit smoking (Guha et al, 1998; Saha,

Where dose arsenic occurs- Arsenic occurs in many minerals, it is most often a mix with sulfur and metals.

Arsenic is one of the most toxic elements that can be found on Earth. Arsenic has a symbol of As and an atomic number of 33. It is a metalloid which gives it both metal and nonmetal characteristics. Arsenic has many allotropes, but the gray form is important for industry. The three main allotropes are metallic gray, black, and yellow. Gray arsenic is brittle and has a low hardness (based on the Moh’s hardness scale) yet a high density. Yellow arsenic is soft and waxy. It is least dense and most toxic. It is also transformed into gray arsenic by light. Black arsenic is brittle and glassy. It is a poor electrical conductor as well. Inorganic and organic compounds of arsenic are found in many places among the earth.

Access to clean water is a right that should be entitled to all people. The harsh reality is that this is not always the case. Contaminated water comes in different forms such as physical (appearance), chemical (natural/man-made compounds or elements), biological (organisms), and radiological (emitting ionizing radiation). Both developed and developing countries have polluted water, and it just may be more apparent in developing countries because of the lack of resources. Water pollution has a negative effect on the growing population involving a fetus and a child’s physical development. The ingestion of contaminated water through a maternal mother or young child may have serious implications. This includes short and long-term effects, along with the difference between the location of in the United States and Nigeria having contaminated water.
