A contractor is renovating an old building into apartments. As he tears down existing drywall he notices there is Asbestos inside the walls. Asbestos is very deadly when it is airborne and since this is intended to be a home for families with small children it must be removed. This research paper is going to talk about the hazards of Asbestos. It may cause and how to remove it and talk about what Asbestos is.
Asbestos is a fibrous mineral that has been used in many different things. It was first used around the 1879 in Quebec Canada.* It was used a great deal until the 1980`s when it was determined that it caused throat and lung cancer.*
The most common way that Asbestos was used was in insulation. Is was used in house`s in the floor tiles which you could get in all different kinds. And it was used in the walls to keep in warm in the house the main reason is was used in the walls was cause it didnt cause fires it protected house`s from fires but since it was found to cause cancer they try not ot used it in house. But it was also used in public schools in there floor tiles and ceiling tiles as well and on the pipes in the ceiling. Asbestos is also used in apartment buildings in pretty much the same as house`s and public schools. It is used in the floor tiles and in the pipes in the ceiling. Asbestos was used in pretty much every building from the time period of 1879 when they first found it to the early 1980`s when they found out that it causes many different kinds of cancer. And the reason they used asbestos in houses or in all the stuff they put asbestos in was they believed that in would prevent things from catching on fire.*
There are very many hazards when using Asbestos. One of the hazards in using Asbestos is that it...

...from those items*.
The last step in removing the asbestos is getting rid of it. It can only be disposed at approved landfills. You must call your state’s department of environmental Quality to find out where these are located and the fees that will be charged*.
In conclusion, Asbestos is very dangerous to humans and can be found in many common buildings and items that are used each day. It also costs four dollars to remove every cubic yard if you hire a contractor to remove it. It very expensive because of the deadly risks involved in the process of removal. If you are a contractor and you are renovating an older structure be aware the asbestos that could be found in the building. If you run into asbestos don’t just keep working because it is very deadly when airborne, call a licensed asbestos abatement contract to do the removal properly and safely.
The Lowry Landfill Superfund Site is located in Arapahoe County, Colorado, approximately 2 miles east of Aurora. It consists of approximately 507 acres of waste disposal area and is operated by Waste Management of Colorado, Inc. The land surrounding the site consists of native prairie grass and a wetland located along a local creek. Sections around the site are zoned for agricultural use including cattle grazing and non-irrigated wheat farms. 1 The area is home to numerous endangered species including the bald eagle and peregrine falcon. Due to the large amounts of wastes disposed on the site between 1965 and 1980, it became extremely contaminated with a variety of inorganic and organic contaminants. From 1984 to 1993, the EPA oversaw remedial investigation and feasibility studies that were performed by all responsible parties. Since its listing as a superfund site in 1984, multiple remedial actions have been performed in order to rehabilitate the site. These include clay barrier walls around the site, a groundwater collection system, a soil cover for the main landfill, as well as a landfill gas collection system. Groundwater that is collected on the site is treated at an onsite water treatment facility. In 2007, construction began on an onsite gas to energy plant that utilizes the methane produced by the landfill site. The electricity produced by the plant is enough to power 3000 households. 1 Today, use of land and groundwater on and near the site is still restricted by the state of Colorado.1
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...
... in inhabitants living close to smelters and arsenical chemical factories. Citizens who live near waste sites with arsenic may have an increased risk of lung cancer as well.
In some cases when working in worse areas a face mask maybe more suitable for the job. When working in areas with possible asbestos sightings wearing a face mask will decrease the chances of ‘asbestosis’. Asbestosis can cause pleural disease, mesothelioma and in some serious cases, lung cancer. When using a face mask make sure it is properly fitted to the size of your face and make sure there is no gaps in between as the dust can find its way through, and also make sure the face mask isn’t worn out and is safe to use.
When someone works in an environment where they are exposed to chemicals, dust, fumes and molds, they are more likely to develop asthma. Along with asthma, constant exposure to chemicals and vapors can cause serious lung problems that can develop into more serious lung problems.

Smoking is leading cause of lung cancer. Smoking causes more than 80% of lung cancer cases. When you smoke you are taking in more that 4,000 different chemicals, which are all proven to be cancerous. Even if you do not smoke you are still at risk for getting lung cancer. Second hand smoke is just as bad as smoking itself. Each of the harmful chemicals can still enter into non-smokers lungs when they are around smokers. Radon is also a leading cause of cancer. Radon is a radioactive gas that is invisible and odorless. Radon can be found in the surface of the earth. When people come in contact with radon it cause the same results as smoking, the cells be come usual. Thus leads to lung cancer. People can also come in contact with carcinogens while they are at work. Many cancer-causing chemicals can be found in the work place such as asbestos, uranium, arsenic, and petroleum. If you are exposed to these carcinogens for long periods of time, just like smoking or radon, you will develop lung cancer.
Radon gas is currently the leading cause of lung cancer in the nonsmokers. Radon gas is harmless in small amounts but sometimes becomes concentrated in homes built on soil wi...

Radon is formed as one part in the radioactive decay chains of thorium and uranium as they decay into lead. As radon decays, it produces decay products. These products stick to things in the air like dust particles. If these dust particles are inhaled the can stick to ones lungs and cause lung cancer. Several studies have proven that those who breathe in radon gas are more likely to have lung cancer than those who don’t. This therefore makes radon a considerable hazard in workplaces such as mechanic shops and ship yards. Radon poisoning comes in second to lives claimed from lung cancer only to cigarette smoking.
BACKGROUND Types of Silica Crystalline silica may be of several distinct types. Quartz, a form of silica and the most common mineral in the earth's crust, is associated with many types of rock. Other types of silica include cristobalite and tridymite. Potential for Exposure During Construction Concrete and masonry products contain silica, sand and rock containing silica. Since these products are primary materials for construction, construction workers may be easily exposed to respirable crystalline silica during activities such as the following: Chipping, hammering, and drilling of rock Crushing, loading, hauling, and dumping of rock   high dust concentrations.

Technological and accidental hazards can be occur without warning and can be both hazardous material incidents and failures at nuclear power plant. In some cases, victims that have been exposed to harmful chemicals or radiation show little to no symptoms until several years later. There are an increasing number of new substances and chemicals being manufactured which has increased the likelihood of a hazardous material spill or release. This also increases the risk to the environment and to the health and safety of a community.

Traditional methods for cleaning up contaminated sites such as dig and haul, pump and treat, soil venting, air sparging and others are generally harmful to habitats. Some methods strip the soil of vital nutrients and microorganisms, so nothing can grow on the site, even if it has been decontaminated. Typically these mechanical methods are also very expensive. Most of the remediation technologies that are currently in use are very expensive, relatively inefficient and generate a lot of waste, to be disposed of.
