Essay On Isotopes

A radioactive element does not have any stable isotopes, which means it may spontaneously degenerate, emitting alpha particles, beta particles and occasionally gamma rays. Some examples of radioactive elements are uranium, promethium and curium. Radioactive elements could be used either negative or positive.

The next piece of evidence showing environmental determinants to health is the air samples taken from the African American community’s residents. Moreover, the air samples taken from the Norco residents living close to the refinery show higher levels of toluidine and benzene, known cancer and disease causing chemicals, than averages from the rest

Gasoline are complex mixtures of hydrocarbons (Gary et al, J., 2007) additives, and blending agents. The composition of gasoline depends on the refinery processes, the crude oil used, the overall balance of product demand, and the especially the product specifications. The typical composition of gasoline hydrocarbons (% volume) is: 4-8% alkanes; 2-5% alkenes; 25-40% isoalkanes; 3-7% cycloalkanes; l-4% cycloalkenes; and 20-50% total aromatics (0.5-2.5% benzene). Table 1 shows

When crude oil is refined there is an abundance of gas that is released into the surrounding air. Some of the components that are emitted include, but are not limited to sulfur dioxide, carbon monoxide, and methane (U. Rehman, personal communication, October 1, 2016). This has a tremendous impact on the air quality near a refinery. The poor air quality that is caused by pollutants is harmful to humans and other living

Uranium can be used to produce nuclear energy, it's renewable, and it means less pollution which in turn helps the environment.

In this Preliminary Public Health Assessment (Pre-PHA), we evaluated exposure of the Milneburge neighborhood community to contaminants in response to their public health complaint with the City of New Orleans. . The homeowners in the neighborhood started to complain of nausea, headache, and dyspnea when they work in their back yards and reported water runoff and soil erosion from the waste management site. So, they were really concerned about their children health because they used to play in the area. As a result of that, we evaluated some polycyclic aromatic hydrocarbons. Polycyclic aromatic hydrocarbons (PAHs) are chemical compounds found in nature or released from burning of coal, oil, tobacco, and wood. Some of these compounds are toxic to lung, liver, and skin. By such Pre-PHA, We can know if the site is extremely contaminated or not and we can assure residents and give them answers about their concerns.

On December 2nd 1984, 40 tons of deadly Methyl Isocyanate (MIC) gas and other toxic gasses were released in to the atmosphere from Union Carbide India, Limited’s (UCIL) plant in Bhopal, India. Water meant for cleaning internal pipes was mixed with MIC, due to a faulty valve, which led to an exothermic reaction. The pressure and heat from this powerful reaction led to break down of a safety valve which then caused MIC gas to be released into the atmosphere.

“The Nuclear Age,” written by Tim O’Brien, was a short story poorly known during the 1980’s. Tim O’Brien wrote this story during the late 1980’s sometime after he returned from the army. He wrote many of his stories to describe some of the things he saw and experienced in the army. “The Nuclear Age” was one of Tim O’Brien’s later stories that was not well received at the time it was published.

The Massachusetts Department of Environmental Quality Engineering took ground water samples that showed volatile organic chemicals (VOCs) in the supply well. This well was formerly used for drinking water for the community. The results indicated that the

World War II spanned from September 1, 1939 to September 2, 1945 and resulted in approximately 80 million deaths worldwide. In 1939, German scientists made an incredible discovery in nuclear science, leading to the high possibility of a Nazi atomic bomb. As soon as word broke out, Albert Einstein frantically reached out to Roosevelt, explaining that the United States needed to beat the Axis powers in developing this new, deadly weapon. In the early 1940s, the United States government and the country’s smartest scientists had began to build one of the deadliest weapons in history.

The word atom comes from atomos, meaning indivisible as an ancient Greek word. Demokritos, a Greek philosopher, maintained that all matter could be divided and sub-divided into smaller units. Eventually there would be a tiny particle that could not be divided any further - an atom. They said that this is remarkable because the ancient Greeks could not observe and experiment

The Industrial Revolution sparked a need for large sources of energy. Human and animal labor could not provide the power necessary to power industrial machinery, railroads, and ships. The steam engine and later the internal combustion engine provided the bulk of the energy required by the industrial age. Today most nations are still heavily reliant on energy that comes from combustion. Usually coal, petrolium, and natural gas are used. Some hydroelectric, wind power, and nuclear fission sources are used, but in the US they accounted for less than 20% of the total energy consumption in 1997 (1). Many experts are worried that natural resources such as coal and petrolium are being depleted faster than they are being replenished, which could

In today’s day and age many people around the world have become dependent on what seems like useless or needless things such as the internet and television. This is one of the negative effects of science and the technology that comes with it. Some of these technologies seem harmless, like cellphones and computers, but it seems as the years progress people want more and more power, literally and figuratively. The element uranium is a perfect example; this element has the power to do well in generating power for millions of people, and the power to do wrong in nuclear warfare.

Since the Industrial Revolution, there has been an increased presence of pollutants and carcinogens in the environment, specif-ically in urban areas.1 The presence of airborne pollutants can lead to an increase in allergic reactions and asthma rates. A common airborne pollutant is carbon monoxide (CO), which is commonly found in diesel exhaust. It is an odorless gas produced from me-thane and non-methane hydrocarbon oxidation.2 The toxic gas eliminates and takes the place of oxygen in the form of carboxy-hemoglobin when it binds to hemoglobin in red blood cells. It also affects the binding sites of heme groups, which complicates the transfer of oxygen to tissues.3 The majority of deaths from carbon monoxide poisoning is brought on from car exhaust.4 Between the years 1979 and 1988, 57% of deaths from carbon monoxide poi-soning were brought from car exhaust. There tend to be higher rates of carbon monoxide poisoning from car exhaust in northern regions, where temperatures are relatively low (Figure 1). 5
