Due to the level of toxicity that abestos consist of, many people are surpries to learn that it is a natually occuring mineral and not a made made material. However, not only is asbestos a natrually occuring mineral, it's toxitity wass realises as far back as the days of the anceint Egyptians.
Historic evidence demonstartess that asbestos has been mined and utilzie for over 3000 years. Historic evidence demonstartes that the Persians, Greeks and Egypitans, utilzie it for a variety of pupose such as clcothing, insulation and as a flame and heat retardaent. In fact, due to the fact that asbestos is a poten flame retarded, the name itself dervices from a greek term which means inextinguishable.
WHile you may assume that sociaty did not realise the dangers that asbestos preesent until revently, this is false. Ancient visilizations realized that their asbestos works eventually devloped a wide variety of lung illneses, so much so that a promiment Roman observer even adised that workers should be protected and as such, the ancient verison of what i now reffered to as a dust mask was created to protect asbestos miners.

The primary reason behnd this was due to the fact that it was utilzied as insulation mateial for pipes, boilers, steam clocmotives, fire doors and brak and clutch linings. During this time it is beleiveed that millions of tonnes of asbestos was mass
secret from the workers. The workers eventually found out how unsafe the plant was from

The James Hardie Industries is a an industrial building materials company, head office in Ireland, manufactory and developing materials, technologies and processes for the production of building materials. For a great deal of the twentieth century, James Hardie was the leading producer of asbestos cement sheet and other building products, which used asbestos as a support material in Australia. However working with James Hardies’ products containing asbestos caused people to develop asbestosis and malignant mesothelioma. As James Hardie was one of the companies involved in the mining of asb...
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.
Arsenic is quite common in nature, but is rare as native. It occurs free in nature, but is most often found in the minerals arsenopyrite, realgar and orpiment. There are three allotropes or polymorphic modifications of arsenic; gray, yellow, and black arsenic. Gray arsenic is the most common, the metallic ...
As the Industrial Revolution began, many factories were constructed and along with that, bad air to the environment. Pollution came about and filled up the entire sky with black smoke, as shown on document seven. While the factories produced not only materials but also pollution many people, especially factory workers, got sick and eventually died. Many factory workers got sick due to the enclosed areas that they worked in. Not only that many of the workers were surrounded by massive and dangerous

year and one in one hundred workers was killed. The year of 1910 was the worst years for the railroads, 3,383 workers were killed and 95,671 was injured. For the injured workers and the workers that were killed received no compensation at all. In some cases, the workers who were injured or killed got a little more money than burial expenses. In Pennsylvania coal fields the bosses thought they were doing each family a favor by giving the deceased man’s son the job to take over their father’s job. The employers were not liable for the injuries or deaths that happened at the factories. Diseases were also a huge problem in the factories. Diseases such as black lung, white-lung, and silicosis were spread across the factories.
Radon gas was found in the 1870s, when some scientists were mining for ore in Ore Mountains in Schneeberg, Saxony. The area has a high content of radon in the tunnels because the area has been mined since the 1470s. The scientists later discovered that 75% of the miners died from lung cancer but it did not shut down the tunnels until 1950.
It was clear that the governments in America would not issue a permit to Union Carbide plant under such circumstances, which lacked severe environmental standards and permitted slum dwellers to live near the plant and so on. Such actions were the ones that led to more deaths. Before the major gas leakage from the MCI unit on December 3, 1984, some people were killed because of phosgene gas leakage. However, no one took it seriously, despite the media report. One of the reasons that people ignore this was because people didnt know the potential danger of the chemical plant.
Asbestos is a mineral that was used prevalently in the middle 1900’s as a building material. Asbestos is a naturally occurring mineral in the earth’s crust, that was once mined in the United States. Currently, the mining of asbestos is banned in the United States, and the use of asbestos is highly regulated. During the peak use of asbestos, it was used primarily for its insulating properties, for heat protection and sound dampening. Some examples of use include fire protection equipment for fire fighters, drywall, ceiling tiles, and insulation around pipe and boilers. Many schools built during the mid-1900’s contain asbestos. For this case study, a hypothetical school, Big Bend Elementary, contains

Very pure limestone is procesed into lime, wich is then used in a wide variety of agricultural, industrial, and construction activities. Other rocks crushed for building materials include basalt, used for railroad track beds, and marble, used for fancy terrazzo floors.

One of the biggest problems that people are faced with on a day-to-day basis is cigarette smoke. The sole cause for 480,000 deaths each year just in the United States is accredit to cigarettes(CDC). For a lot of the smokers the habit of smoking happens to assist them when under stress and dealing with issues that are unmanageable. Some smoke to appeal to their peers or simply because it “feels good.” Smoking one cigarette can lead to a major addiction. The effects of smoking hurt oneself and those amongst us. Smoking Kills as the ad portrays this revolver and cigarettes as the bullets, and also lists the side effects of smoking. Cigarettes causes cancer, increases the risk of you getting a stroke, highly addictive and causes a lot of health problems. Nearly 16
