Arsenic Research Paper

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, 2013). The main trend that researchers have been focusing on is the amount of arsenic that is contaminating drinking water. Arsenic has been known to be a health issue in water for many years, but it was not until the 1980’s and later that the government and Environmental Protection Agency (EPA) started to really crack down on monitoring it (Agency for Toxic Substances and Disease Registry [ATSDR] , 2010). Before 2001 the legal amount of arsenic that was allowed in drinking water was 50 parts per billion (ppb), but since then public health officials and the government realized that this amount of arsenic in the water was making people sick (ATSDR, 2010). So on January 22, 2001, the EPA adopted a new standard of 10 ppb of arsenic is drinking water (ATSDR, 2010). This level has been tested to be the safest allowable amount of arsenic in drinking water to be ingested by humans. To this day parts of the world and about 2% of the United States are still having issues with keeping the

The element I decided to do was lead. Lead was used many years before and it is still used a lot today. Lead is still very useful and is found in many things that were used a long time ago and things we still use today. Lead is a very poisonous element that can really harm your skin and your body. Since lead is very toxic, it’s not recommended for children. Lead is also the heaviest of the carbon family.

A little more than a hundred milligrams of arsenic trioxide would can cause death. In extensive measures, arsenic can kill quickly and the person would die before the onset of the symptoms. Indications of arsenic poisoning are: irritation of the gastric and intestinal zones alongside extreme spewing and looseness of the bowels spotted with blood, another sign is also unbearable torment, and extreme thirst, and a general assault on every one of the frameworks of the body is experienced by the patient. In the occurrence that the patient is lucky, the cardiovascular framework would crumple and demise would happen inside a couple of hours. Be that as it may, a few people stay alive for a few days. This is in light of the fact that the patient stays normal.This is made worse because the patient remains rational and intelligible. If arsenic does not kill you right away, it causes cancer which will eventually lead to

It easily combines with other natural occurring chemicals. When heated with oxygen, it becomes white, crumbly powder. In this form it is called arsenic trioxide or white arsenic. White arsenic was the poison used at the Shelbourne. It was a favorite of some of history’s most feared poisoners, like the ones who made Jean Crones look like the amateur he was. Lucretia and Cesare Borgia used white arsenic but experimented with different ways to make it more deadly. They would cook it into more intense solution, mixing it with other poisons. Basic arsenic is also deadly; the first case recorded of homicide with the pure element was reported in 1740, when a girl poisoned her father and three sisters by serving them a dish of dried pears that had been boiled in water containing rocky ore from a nearby mine. White arsenic is a better tool for criminal uses; slipped easily into food or drink. One of the best known nineteenth-century American forensic scientists, Rudolph Witthaus, once tried to estimate arsenic’s popularity as a murder weapon. He found 820 arsenic- caused deaths recorded between 1752 and 1889, and also found that almost half were

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

- Tests determined increase levels of arsenic, selenium and other metals in the surrounding waters and in sediment nearby.

Chez as known as Ghost boy is a superhero of his birth city called Midox. He is tall and strong. He has an ability to disappear and move just like an ghost. But he is also smart because he invented some tools to make him even faster and stronger.

iii. Aluminum is one of the most abundant elements found in the environment. [4] Therefore, human exposure to this metal is

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

in mining and metalworking, and has been associated with poisoning from items such as dyes,

The health hazards for humans who come in contact with contaminants from exposure to polluted water can have long term effects on the body causing possible organ failure and death. Contaminants and chemicals such lead and mercury can bring about many minor illnesses ranging from nausea, lung irritation, skin rash, vomiting, and dizziness, to the major diseases that include cancer, liver and kidney damage, disorders of the nervous system, damage to the immune system, birth defects and even death.

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,

You may well know that aluminium, along with a number of other contaminants, can be found in your drinking water but did you know why it’s in your drinking water? More importantly, do you know if it’s even safe? Aluminium is already present in our soil and as a result will be found in untreated sources of drinking water such as wells. On top of this, aluminium compounds are also used to help remove any impurities at water treatment works. Aluminium happens to be very useful in the battle against cloudiness and bacterial content before the water enters the final stages of disinfection and treatment however, as a result of its use a residual amount remains in the water supply. The legal standard for

This chemical tends to occur naturally in soil, so sometimes it can make its way into your well. If you drink too much water contaminated with arsenic, you will be susceptible to an array of harsh side effects such as vomiting and a burning feeling. If your water supply is never checked and you drink arsenic-laced water regularly over time, your risk factor for developing several kinds of cancer will increase substantially.

Throughout the play, Arsenic and Old Lace, Teddy is characterized as being insane because he believes that he is President Roosevelt. A number of the characters are thought of as being insane, but Teddy differs greatly in that he is harmless. He would never do anything to hurt anyone. Teddy’s insanity shows when he tells Elaine that he is going to Panama, but it is actually the cellar. When Mortimer speaks to Teddy, he replies as if he were the president. He says “Bully, thank you. Just bully! What news have you brought me?” This demonstrates that Teddy truly thinks that Mortimer is bringing him information as president. When Teddy goes down to the cellar (Panama), he thinks that he is digging locks for the canal, but he is actually digging graves for his aunts’ “charity”. This shows how naive he is because he doesn’t realize that he is helping the charity by digging graves for the victims. He also
