Download file to see previous pages The two metals are mined as ores with impurities such as lead, selenium, benzene, cadmium and numerous other impurities. The ores are melted in a furnace till they reach their boiling points which are 7000 degrees Celsius. The boiling point of other impurities in these ores is lower and, therefore, by the moment aluminium and steel begin to boil the impurities are already in vapour form which is condensed to their respective pure metals such as lead, and selenium (Fletcher 10). Aluminium and steel are left in their furnaces as a sludge that is condensed with the help red sludge as a reducing agent. The success of steel and aluminium refining depends on how well the vapour of impurities is condensed and not released into the atmosphere. It also depends on how the manufacturer is ethical so as not to dump these wastes illegally. When released illegally, these heavy metals will be swept off by running rain water and taken into rivers. This causes these metals to de eaten by fish. This fish is then consumed by human beings. As these metals cannot be digested, they accumulate in the body causing various ailments such as cancer. In addition, if the red sludge is not well disposed of it causes soil alkalinity that is expensive to correct. The substance also contains heavy metals that it picks from the molten aluminium. Its proper disposal is, therefore, important. The refining of oil is also an energy intensive process. Crude oil is boiled in a fractionating column that allows the various components to evaporate when its boiling point is reached. When the boiling point of plastic elements in crude oil is reached, the liquid is collected and molten into various forms. The success of this process also depends on how impurities such as plastics are trapped before they escape into the atmosphere as pollutants (Fletcher 10). Similarities The refining of the three elements involves melting their original complex compound, that is, crude oil, steel ore and aluminium ore. The impurities of these ores evaporate and these elements are left in pure form (Smith 13). US industries and Reporting US have many industries dealing with steel, aluminum, and crude oil. These industries are required by law to submit annual environmental audits of their activities. These reports outline the effects their activities have on the environment. They also outline the measures they are taking to control the bad effects of their production process. They are also required to employ latest technologies to save energy use and conserve resources. Environmental Protection Agency monitors all industries to ensure they have complied with environmental laws (Kubova 12). Fairness of the Industries The cases presented in the websites do not give a fair compensation to those who were affected by the sludge and toxic smoke from the steel industry. This is because they are reported to be dumping illegal toxic materials beyond levels that are agreed. They also promise to restore degraded land areas of which they cannot be restored completely. They also give false information that the sludge is not harmful to both people and environment (Olivares 12). This is not the reality because people had to be taken to hospital with burns and some also died due to harmful effects of the sludge. Are there differences in pollution generation based on country of production? Companies from developed countries shift their industries to third world counties because they often find it ...Download file to see next pagesRead More

...? Interactions of Hazardous Materials No: Interactions of Hazardous Materials According to the given incident, the ‘class 8’ label on the tanker shows that the liquid is corrosive (like sulphuric acid, hydrochloric acid, Sodium hydroxide or potassium hydroxide). The NFPA diamond with a 0 at 12 o'clock, shows that the liquid will not catch fire, a 2 at 3 o'clock shows that the liquid will undergo violent chemical change under normal conditions, a 4 at 9 o'clock shows that the liquid is deadly and it should not be inhaled or allowed to touch a body part under any condition. A slashed W at 6 o'clock depicts that the no water should be allowed to make contact with the...

Hazardous Wastes and Contaminated Sites

...HAZARDOUS WASTES AND CONTAMINATED SITES A contaminated site is a site at which hazardous substances occur at concentrations above background levelsand indicates likelihood to pose an immediate or long-term hazard to human health or the environment (Project Participants and their Organizations 2003). It is stated that to be able to meet this definition of a contaminated site, an area must be an identified delineated area of land, such as a transport depot or a landfill. It must have an identified contaminant, a hazardous substance, which is present at a known concentration in soils on the site, or is discharging from the site. The identified contaminant in...

Hazardous Materials

...Running Head: SKIP NAVIGATION LINKS Skip Navigation Links Hazardous materials (HAZMAT) are the materialsthat pose as a threat to the environment or human health if released in large amounts. Incidences related to hazardous materials are normally complex in the public safety industry. Some of the risks that may arise due to the use of hazardous materials are; a fire hazard, an explosion, threat or a chemical gas threat. They occur due to the logistics involved in the response and operations that have to do with the way multiple units function at a scene .The multiple functions involve contraction and expansion as well...

Hazardous materials

...Hazardous Health Care Materials: Health Impact and Waste Minimization Introduction Hazardous materials have been attributed to the majority of the health problems in the society. The increase in the amount of hazardous material has resulted in an increase in the health cost and burden due to diseases. This is because hazardous materials have both direct and indirect effects on human life. They are also associated with the pollution of the environment. A hazardous material is defined as a substance that threatens to harm the environment or the public...

Hazardous Materials Chemistry for Emergency Responders

...Chemistry of Hazardous Materials Chemistry of Hazardous Materials A) White phosphorus also known as yellow phosphorus requires safety measures like wearing gloves while handling because of the significant hazard it can cause to its user. This allotrope is tremendously toxic and can be lethal. Moreover, white phosphorus can cause deep slow healing burns and is highly inflammable and reactive to the extent that a fire can erupt, however, while burning white phosphorus can also cause damage to the kidneys, heart, or liver. Furthermore, prolonged skin exposure to phosphorus can cause dermatitis. Therefore, in order to avoid hazards that may...

Red diamond is at 12 o’ clock and the other labels show yellow diamond at ‘2’ position at 3 o’clock (“NFPA Labeling Guide”). The labels show that the liquid dripping out of the tanker is flammable, totally vaporize at atmospheric temperature and pressure and will completely burn with a little spark. On the other hand, the label with the yellow diamond at 3 o’clock depicts the liquid that is dripping out of the tanker is unstable but do not explode at normal condition.

...should be covered so no spark occurs. These transports should not be left alone. Like other hazardous materials, explosive transports shall be clearly marked as such. Finally, the Department of Labor (2012) requires a working fire extinguisher that drivers are trained to use in the transports. Explosives are different from other hazardous materials due to the mass destruction caused. For example, an explosion can destroy a road, railway, or ship and everything in the vicinity. A toxic gas leak can lead to evacuations, but can be cleaned up with little or no life loss. The property damage is less as well. Once something explodes it cannot be taken back. It damages,...

Reprocessing Nuclear Fuel

...Reprocessing Nuclear Fuel By Introduction The nuclear power generation and other applications of nuclear fission and corresponding nuclear technology including the researches in the fields of medicine generates radioactive wastes as byproducts The wastes that results from nuclear fuels are not necessarily hazardous or hard to manage. Such wastes can be treated as waste or used as valuable materials for production (Toth, 2011, pp312-378). The radioactive wastes are normally kept in unexposed condition for a particular period to allow for them to decay in order to reduce their radio nuclide. Radio nuclide is a major...
