1. What are three primary emissions from the nucleus of a radioactive atom?
Alpha radiation, Beta radiation, and Gamma Ray. 2. Why are alpha particles of concern as a contaminant in drinking water?
Alpha particles (radiations) are naturally occurring radionuclide present in the drinking water. They are positively charged and released from the core of some radioactive elements. Heavy elements such as radium and uranium are found naturally in the earth’s crust emit alpha particles which are released into groundwater when they decay or break down, the energy they release is called ionizing radiation. Groundwater is a common source of drinking water. In drinking water the alpha radiation can be found in the form of dissolved minerals, or in the …show more content…
The radon is a gas that cannot be seen, smelled, and tasted. Actions like taking showers, doing laundry or running a dishwasher can release the radon into the air inside home. Breathing the air that is associated with high levels of radon over a lifetime (daily bases) increases a person‘s risk of getting lung cancer. Ingestion of radon (Ingestion Risk) in water is also thought to pose a direct health risk by exposing radiation to the sensitive cells in the gastrointestinal tract and in other organs once it is absorbed into the bloodstream. Therefore, radon in drinking water could potentially produce harmful health effects in addition to Inhalation Risk such as lung …show more content…
The process is by exchanging the radium for sodium or potassium. When the softener is cleaned, the radium is cleaned out with the wastewater into a disposal site such as a leach field or municipal sewer. Reverse Osmosis (RO) is another type of treatment .In (RO) process, water is forced under pressure through a membrane leaving the radium behind. The radium is then cleaned out. The process is relatively slow and may be more proper for a household rather than a PWS. Also greensand filtration, granular activated carbon, and lime softening are other options for removal of radium in the PWS. Uranium can be treated throughout an ion exchange which is a treatment similar to water softening except that the uranium is removed and exchanged for chloride. Reverse Osmosis also removes uranium. Additional treatment options are available to the PWS meanwhile are not available to homeowners such as lime softening (to reduce radium and uranium) and coagulation and filtration (to reduce uranium). Radon can be treated throughout Aeration, which can remove radon from the water. A large volumes of air are blown through the water or the water is squirted so that it is exposed to the air. As the radon gas leaves the water and enters the air. Then the air vents outside, and the treated water is re-pressurized and piped to

Flame Photometery Report

...UNIVERSITY OF NAIROBI DEPARTMENT OF MECHANICAL ENGINEERING BULUMA MARK EUGINE F18/1494/2011 GROUP 4 EXPERIMENT 3: FLAME PHOTOMETRY. THE OBJECTIVE OF THE EXPERIMENT. 1. To determine presence and concentration of sodium ions in drinking water. 2. To determine the presence and concentration of potassium ions in an unknown fertilizer sample. THEORY BEHIND THE EXPERIMENT. The major cation of the extracellular fluid is sodium. The typical daily diet contains 130-280 mmol (8-15 g) sodium chloride. The body requirement is for 1-2 mmol per day, so the excess is excreted by the kidneys in the urine. Hyponatraemia (lowered plasma [Na+]) and hypernatraemia (raised plasma [Na+]) are associated with a variety of diseases and illnesses and the accurate measurement of [Na +] in body fluids is an important diagnostic aid. Potassium is the major cation found intracellularly. The average cell has 140 mM K+ inside but only about 10 mM Na+. K+ slowly diffuses out of cells so a membrane pump (the Na +/K+ATPase) continually transports K+ into cells against a concentration gradient. The human body requires about 50-150 mmol/day. Hypokalaemia (lowered plasma [K+]), hyperkalaemia (increased plasma [K+]) and hyperkaluria (increased urinary excretion of K+) are again indicative of a variety of conditions and the clinical measurement of [K+] is also of great importance. INTRODUCTION TO THE EXPERIMENT Flame photometry is a traditional and simple method for determining sodium and...

Fracking

...companies actively search for natural gas inside of the shale rock formations. There is a two-step process for drilling natural gas by using hydraulic fracturing. The first is that a production well id drilled thousands of feet deep into the earth’s surface and the gradually leveled so theat the drill bit is traveling horizontally through the ground. The second step is where the name fracking comes from because this is where the process of mixing sand, water, and chemicals (many which are known to be harmful) are forced under very high pressure down into the shale rock through the horizontal part of the drill. The extreme pressure causes the shale rock to fracture releasing the natural gas within. The added chemicals help reduce problems such as a buildup of bacteria and mineral deposits. Fracking is a very water intensive process and uses up to four million gallons of fresh water for each well, and with about thirty-five thousand wells in the United States, fracking consumes the same amount of water as five million people. Most of the water used remains trapped down in the rocks where the natural gas previously was, but about...

Environmental Studies

...Environmental studies Name: Institution: Date: Development of the drinking water standards for arsenic since the year 2000 Exposure to Arsenic has become a considerable global environmental health concern as contact through contaminated drinking water leads to cases of several medical conditions and ailments as well as human reproduction and development effects. The source of arsenic in drinking water consists of natural supplies such as rocks, soil and from human activities for instance in preservatives, paints, and agricultural activities. There are increased levels of arsenic in the ground water sources as compared to surface water and this makes people who rely on ground water to be vulnerable to water that is contaminated. In the U.S. the mean arsenic levels from the measurements taken from ground water samples is usually estimated at one part per every billion litres of water although in some regions high levels of arsenic concentration in ground water is recorded. There have been several amendments and developments with regards to drinking water standards and contamination from arsenic. The Environmental Protection Agency in the year 2001 enacted a law regarding to the arsenic contamination of drinking water in accordance to the 1995 Safe Drinking Water Act and it set a threshold for arsenic contamination in drinking water at 10 ppb as a replacement for the initial threshold of 50 ppb that was settled on in 1975 (Thomas & Copeland, 2008). The regulation...

Fracking, Is It Worth It?

...Are they willing to risk their health for wealth? That is the question on everyone’s mind in North Dakota right now. North Dakota residents are scratching their heads and asking, “is the money that oil and gas development is providing to our state important enough that we are willing to risk the health of our families”? Why is there a risk? Because the oil companies are not satisfied with reaching oil only a few hundred feet below the surface. Oil and gas companies are interested in retrieving the oil and gas from a layer of shale and dense rocks at depths of 10,000 feet. The oil companies are retrieving the oil and gas from the shale and rock using a method known as hydraulic fracturing (fracking). This method was developed over 60 years ago. The process of fracking injects water, sand, and chemicals through a cement casing or tubing into shale and dense rocks, cracking the shale and rocks to open the pores, allowing the oil and gas to flow more freely to the surface (Svoboda). Even though the oil companies are using less invasive chemicals, leaving behind fewer toxins, they are still using chemicals with health risks attached such as ethylene glycol. The other health concern today is the dumping of wastewater that comes from the fracking process. There were more than 1,000 reported spills or illegal dumps of wastewater and other drilling fluids in 2011, just in the state of North Dakota. This contaminated water has to go somewhere, and it is likely going into our groundwater...

...How environmentally is a hydro-electricity? This question to me seems like a very imaginative and profound to help me dig out all the possibilities towards answering the question in a smart way, conceptualizing it with modern science and technology. As many as 700,000 people a year die from indoor air pollution caused by burning coal for heating and cooking. A quarter of all early deaths are caused by respiratory diseases. This hazardous problem like uncountable diseases and death resulting from advancement in the field of science and technology and this becomes a big issue forcing scientist and economist to research and discover the most efficient and faster way to development with little impact to the living standard and lifestyle of the people. Today, the decision to build more hydroelectric dams is a controversial topic in many parts of the world as people re-examine the environmental impact of flooding large areas of land on wildlife, fish habitat and communities surrounding sites where new hydroelectric dams are being considered. Hydroelectricity also produces more power than any other energy solution, like nuclear power, wind power, solar power, and coal and gas power plants. Hydroelectric power also does not emit greenhouse gases. So it does not hurt the environment by destroying the ozone layer of the Earth. While it does not give off any emissions, it creates a tremendous problem with the environment of the river from which it is harvesting power. For example, a...

China's Ecological Environment

...environmental degradation, and most of this is done by human activity especially international business activities. This essay will look at the impact of economic globalisation on China while focusing on China’s ecological environment. To start off, the essay will look at the definitions of globalisation and economy, followed by China’s change from being an agriculturally farming intensive country towards rapid industrialisation. Because of this activity pollution, emissions as well as environmental degradation resulted in serious ecological problems. International bodies such as the Kyoto Protocol, the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Environment Programme, have stressed the importance or reducing pollution and emissions in developing countries in order to maintain sustainability. Cancer villages are becoming a major concern in China and that was enough to make the Chinese political party to take responsibility and change their views on the ecological environment. The question here is can China implement these changes to maintain sustainability for future generations, and if so what methods are they using to achieved this by? According to Morrison (2011), globalisation is the “process by which products, people, companies, money and information are able to move quickly around the world.” (p. 43). The definition of economy is “the system of activity connected with the production, trade, and consumption of goods and services of a region,...

Blaw Chapter 52

...Chapter 52 A. Introduction 1. Historical Perspective. Begin by indicating why pollution control laws have been enacted. Point out that pollution and pollution laws have existed for centuries, although the 1970's saw an unprecedented amount of environmental legislation, due partly to the increased affluence of our nation at that time and the increasing concern about the longterm effects of pollutants. Note that the interest in environmental problems has taken on global dimensions in the late 1980s and early 1990s; note also that environmental laws and regulations significantly affect not only how companies can do business but also the cost of doing it. At the same time they can provide business opportunities and, in some cases, advantages. 2. Environmental Protection Agency. Point out that EPA has the primary responsibility at the federal level for developing environmental regulations and enforcing the environmental laws. List the major environmental statutes and briefly describe them so that the student has a sense of the breadth of the laws covered in this chapter. Note that a number of the statutes are implemented at the state level with EPA exercising an oversight role. You should note that many states and local governments have enacted pollution control laws; you might want to present examples of state and local laws. 3. The National Environmental Policy Act.

This article highlights an assessment directed by EPA which provides a harsh study on the diversity of instruments by which global warming might negatively impact human health in the United States (US). It further states that heat-related disease will likely increase over years, as will deaths linked to air pollution. Collectively, severe events will impact health and welfare and human systems (Gamble, et at, 2008). For instance, floods could contaminate our drinking water and wildfires could increase air pollution. An experienced scientist, Gamble investigated the effect of climate change on human health and developed a model of studies. He found that climate change increases temperatures and shockingly, more people are expected to die from carbon dioxide (CO2). The author is forthcoming, descriptive, and his work is well-researched.

...FIJI Water Bottled water has become an indispensable prop of the daily lives of consumersalmost anywhere in the world today. It is truly a marketing phenomenon in the 21 centurys globalconsumer culture. Despite having grown up drinking water straight from tap, many consumers now prefer paying for the luxury of drinking bottled water and are raising a generation of children that views bottled water as a superior alternative to tap water. They have learnt to accept paying good money for a commodity which has always been provided, and can still get, for free from taps in their homes. Bottled water barely existed as a consumer product a couple of decades ago. It was mostly found in exotic holiday destinations with poor quality local drinking water to cater for the needsof tourists. Today, we find bottled water in lunch boxes, meetings, lecture halls, tennis matches and the cup holder of the treadmill at the gym. Every convenience store or supermarket offers bottled water for sale. At supermarkets, bottled water is the most popular item by units sold today. When we buy a bottle of water, we are notjust paying for the water itself but the convenience and most probably the artful story which the water companies tell us about the water. Our choice is affected by where it comes from, how healthy we think it is, and what it says about us ¨C in other words, its symbolic meanings rather than the actual benefits. Among the choices that we make for our daily consumer products, bottled water...
