Pollution of Drinking Water Supplies Essays - 803 Words

It is widely known that water covers almost three-quarters of the Earths surface. However, it is not widely known that more than 99 percent of Earths water is unusable by humans and many other living things. Less than one percent of water which supports most of the forms of life we are familiar with. Unfortunately, that one percent of fresh water becomes more polluted every year. The pollutants that fill our waterways each year are largely unknown. Water pollution comes from a number of unique sources, such as industrial waste, urban storm-water, agricultural runoff, various household chemicals and even nuclear waste. Combining these points of pollution with the increase in global population results in a continuously decreasing†¦show more content†¦This rapid pumping has created huge sinkholes on the land surface in some areas. Overpumping in coastal areas like Florida has caused the water table to drop below sea level and has contaminated the freshwater with salty ocean water. Overpumping of rivers for agricultural and personal use has caused some rivers like the Colorado to dry up before it reaches the ocean. This not only harms the ecosystems found around the rivers, but also prevents essential nutrients from rivers from entering the ocean, depriving fisheries of food and in turn hurting the oceans food chain. The end result of this is a loss in biodiversity and interruption in the food chain. Irrigation of land with water from these rivers leaves the soil full of salts, resulting in the land being unable to produce as much as it would have. In 1972, Congress enacted the Clean Water Act to restore and maintain the chemical, physical and biological integrity of the nations waters. One goal of the Act is to ensure all our sources of water are clean enough to drink and swim in. To date, roughly 65% of our waters meet this goal. Although Congress has enacted a number of public health programs to stabilize the problem, there is still much work that needs to be done. One point of control the Clean Water Act established involved a federal and state partnership to control the discharges from large industrial sourcesShow MoreRelatedThe Factors Affecting Safe Drinking-Water (Planning and Essay Basic)1485 Words   |  6 Pagesaffecting safe drinking water: Describe and explain the different factors effecting access to safe drinking water.

The Legalization Of Illegal Drugs - 1262 Words

Before President Richard Nixon declared drug abuse as America’s number one public enemy in 1971, the United States already had a long history of combating the use of illegal drugs. The first of its kind was the legislation that passed in San Francisco in 1875. This newly passed legislation banned the smoking of opium. However, this legislation seemed to be racially motivated. San Francisco citizens believed that Chinese men who resided in the community, and who were highly regarded as opium smokers, would lure women into opium dens and take advantage of them. In 1909, the United States Congress passed a federal ban on opium. Afterwards, the government began to target cocaine as well. Much like opium, the use of cocaine was also racially†¦show more content†¦Since 1971, one trillion dollars have been poured into the War on Drugs. While this is more than enough money to provide the resources necessary to at least put a dent in the supply and demand for drugs, it has pro duced relatively no positive results. Instead, it has produced racial disparities throughout the entire country. Although white people abuse drugs at a rate that significantly higher than the abuse rates of African Americans, African Americans are arrested at a rate that is ten times higher than that of their white counterparts (Gupta). Many have begun to question if this war is against drugs, or people of color. It seems as if everybody is aware of the racial bias except the elected officials. In March of 2016, a twenty-two year old interview with President Nixon’s domestic policy chief John Ehrlichman was discovered. In the interview, he said that Nixon created the War on Drugs as a way to politically fight African Americans and hippies (Lobianco). In the interview, Ehrlichman states, â€Å"You understand what I m saying? We knew we couldn t make it illegal to be either against the war or black, but by getting the public to associate the hippies with marijuana and blacks with heroin. And then criminalizing both heavily, we could disrupt those communities† (LoBianco).

Gasoline Essay Example For Students

Gasoline Essay Gasoline has gone through many changes in the last couple of decades, both for efficiency and for environmental considerations. During the early 20th Century, the oil companies were producing gasoline as a simple distillate from petroleum, but the automotive engine was rapidly being improved and required a suitable fuel. Engines were modified to run on kerosene, however kerosene-fueled engines would â€Å"knock† and crack the cylinder head and pistons. This then led to the long search for antiknock agents, culminating in tetra ethyl lead. Typical mid-1920’s gasoline was 40-60 octane. The 1950s saw the start of the increase of the compression ratio, requiring higher octane fuels. Octane ratings, lead levels, and vapor pressure increased, whereas sulfur content decreased. Minor improvements were made to gasoline formulations to improve yields and octane until the 1970s – when unleaded fuels were introduced to protect the exhaust catalysts that were also being intro duced for environmental reasons. From 1970 until 1990, gasoline was slowly changed as lead was phased out, lead levels plummeted, and octane initially decreased. With the passage of the US Clean Air Act of 1990, significant compositional changes in gasoline began to be forced on the industry to minimize this major pollution source, and these comprehensive changes are expected to continue well into the 21st Century. Oxygenates, which are actually pre-used hydrocarbons, have been sparingly used in gasoline since the 1970’s for their anti-knock value. Today they are increasingly added to gasoline because research seems to indicate that they help reduce the smog-forming tendencies of exhaust gases by reducing the reactivity of the emissions; therefore making the gases less environmentally harmful. Oxygenates can now replace high-octane aromatics in the fuel, thus dramatically reducing the CO and HC emissions (the â€Å"aromatic substitution effect†). Another advantage to increasing the oxygenate levels in gasoline seems to be that they improves octane levels, but this is still being studied. When tetra ethyl lead (TEL) was first introduced into gasoline during the 1920’s, it became the most cost-effective way to enhance octane while reducing engine knock. This led to major gains in engine efficiency and lower gas prices, which pleased the nation. The toxicity of TEL was apparent from the outset, but people were willing to accept the trade off for cheap, efficient fuel. Up until the late 1960’s, these leads were added to gasoline in increasing concentrations to obtain greater and greater octane. By then, the toxicity of the emissions from gasoline-powered engines was becoming of increasing concern and there was a frantic search begun for an exhaust catalyst that was lead-tolerant. When nothing practical could be found, lead was on its way out as a gasoline additive. The catalytic converters used today are extremely sensitive to lead and thus the gasoline formula had to be radically changed to exclude lead. This has had a very positive effect on the environme nt by reducing the aggregate emission of lead by more than 95%! The known long term effects of chronic exposure to lead in humans results in damage to blood, central nervous system (CNS), blood pressure, kidneys, reproductive systems, and Vitamin D metabolism. Children are particularly sensitive to the chronic effects of lead, with slowed physical and cognitive development and reduced growth especially affected. The largest source of lead in our atmosphere had been from leaded gasoline combustion, but with the phase-out of this lead source, air lead levels have decreased considerably.This is good because lead has been shown to bioaccumulate in the environment and continues to pollute. With the removal of lead and the immediate introduction of exhaust catalysts and sophisticated engine management systems, the United States has made great strides in maximizing environmental and health gains in this area. .ude2c5d217a9a936deeaf3d8e42bfff85 , .ude2c5d217a9a936deeaf3d8e42bfff85 .postImageUrl , .ude2c5d217a9a936deeaf3d8e42bfff85 .centered-text-area { min-height: 80px; position: relative; } .ude2c5d217a9a936deeaf3d8e42bfff85 , .ude2c5d217a9a936deeaf3d8e42bfff85:hover , .ude2c5d217a9a936deeaf3d8e42bfff85:visited , .ude2c5d217a9a936deeaf3d8e42bfff85:active { border:0!important; } .ude2c5d217a9a936deeaf3d8e42bfff85 .clearfix:after { content: ""; display: table; clear: both; } .ude2c5d217a9a936deeaf3d8e42bfff85 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ude2c5d217a9a936deeaf3d8e42bfff85:active , .ude2c5d217a9a936deeaf3d8e42bfff85:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ude2c5d217a9a936deeaf3d8e42bfff85 .centered-text-area { width: 100%; position: relative ; } .ude2c5d217a9a936deeaf3d8e42bfff85 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ude2c5d217a9a936deeaf3d8e42bfff85 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ude2c5d217a9a936deeaf3d8e42bfff85 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ude2c5d217a9a936deeaf3d8e42bfff85:hover .ctaButton { background-color: #34495E!important; } .ude2c5d217a9a936deeaf3d8e42bfff85 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ude2c5d217a9a936deeaf3d8e42bfff85 .ude2c5d217a9a936deeaf3d8e42bfff85-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ude2c5d217a9a936deeaf3d8e42bfff85:after { content: ""; display: block; clear: both; } READ: Hamlet Comparative EssayWhen gasoline molecules in a car’s engine do not burn completely, hydrocarbon emissions occur. The hydrocarbons react with nitrogen oxides and sunlight to form ground-level ozone, a major component of smog. This smog irritates the eyes, damages the lungs, and aggravates respiratory problems. A number of exhaust hydrocarbons are also toxic, with the potential to cause cancer. To combat this, fundamental improvements in engine design have been made, charcoal canisters have been added to collect these hydrocarbon vapors, and exhaust recirculation valves have been installed to reduce the nitrogen oxides.

Training and Development Concepts in Healthcare Field

Introduction This article discusses training and development in healthcare field. The value of training and education in this field is discussed together with the importance of measuring competencies learned through training forums. The process of tracking and evaluating training effectiveness is also outlined and finally a conclusion is drawn.Advertising We will write a custom essay sample on Training and Development Concepts in Healthcare Field specifically for you for only $16.05 $11/page Learn More Training and Education in Health Care Training and education in the field of healthcare are very vital. This is simply because the field is evidence based and always improving. Professionals in this field need to be informed and trained on the latest advances in the field. Minor adjustments in this field often have amplified results. Keeping abreast with new developments through education and training therefore helps to ensure that the best evidence based practices are upheld. It is worth noting that education in theory and practice has to be done hand in hand. Having a solid theoretical background is vital to ensuring that training is carried out well however, theory alone without training will be meaningless. Education and training help in enhancing the efficiency of medical care; errors are pointed out and remedial measures suggested. Sharing of knowledge through symposiums and other platforms helps to ensure that only the best practices are upheld (HSRIC, 2013). Education and training may also be carried out on communication tools. How a provider interacts with patients is of significance as it determines how much the provider will understand the life of the patient. Interacting well with a patient is especially significant for the cases of counseling. It helps the provider to pick the best approach of treatment (HSRIC, 2013). Education and training also helps in ensuring that healthcare providers are compliant with the requireme nts of the healthcare field as pertains to their practice. Non-compliance with the set rules and regulations may lead to a revocation of a practitioner’s certificate. Being informed on one’s area of practice also reduces the risk of being involved in legal suits as a result of malpractices (HSRIC, 2013). Importance of Measuring Competencies Measuring of competency levels is significant in the healthcare field for various reasons as discussed below. Healthcare Reform: The need to reform the healthcare field has necessitated measuring of competency of practitioners and new graduates. It is assumed that one of the factors that will ensure that reforms in healthcare succeed is competent practitioners (kak, Burkhalter, Cooper, 2001).Advertising Looking for essay on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Organizational Performance: Healthcare providers engage in general and specific competency checks to fin d out the efficiency of their organizations in respect to the services they offer. Such checks help an organization to engage in remedial measures which might take the form of education interventions or other forms (kak, Burkhalter, Cooper, 2001). Liability and Ethics: Institutions are liable for the services their employees offer. Institutions are therefore morally obligated to guarantee that their employees are competent enough to serve at the capacities that they serve (kak, Burkhalter, Cooper, 2001). Risk Management: It is possible to evaluate how well an organization is versed with emergency procedures related to certain practices through the use of competency assessments. Analysis of the results of competency assessments can be used to offer more training to an organization’s staff (kak, Burkhalter, Cooper, 2001). Introduction of New Products: When organizations introduce new products, competency checks can be used to identify staff members who will readily offer the products or services and those who may require some training to pick up (kak, Burkhalter, Cooper, 2001). Training Exercises: Measuring of competency levels of trainees after a training exercise may help to evaluate the effectiveness of the exercise. A generally low score on competency may be an indication that a training exercise was carried out inappropriately. Competency evaluation of a training exercise may shade some light on areas that need emphasis or better approaches (kak, Burkhalter, Cooper, 2001). Tracking and Evaluating Training Effectiveness Any training exercise usually has a set of objectives to achieve. The evaluation of a training process should use methods which will specifically seek to identify whether the training objectives were met and to what extent. Basically, tracking and evaluating a training exercise involves two processes namely: finding out whether skills were acquired during the training exercise and determining whether these skills are being practic ally applied towards the improvement of performance (Carr, 2002). There are various methods which are used in finding out weather skills have been learned. This exercise is best carried out at the individual level and is helpful to the training department as it shades light on what is to be improved on. Use of questionnaires, knowledge reviews, observations, employee portfolio, and skill gap analysis are some of the popular methods used in determining what has been learned (Carr, 2002).Advertising We will write a custom essay sample on Training and Development Concepts in Healthcare Field specifically for you for only $16.05 $11/page Learn More In determining how the skills are being applied in the workplace to improve productivity, assessment of competency application is carried out. This is usually carried out at the organizational level. This is done by analyzing the performance measures of an organization and the training return on investment (ROI) (Carr, 2002). Conclusion Education and training in the field of healthcare is of great significance. Being an evidence based field, professionals in this field ought to be updated continuously on changes and progresses made. It is also important to ensure that skills taught through seminars and other platforms are learned well and applied to improve organizational performance. This is done by tracking and evaluating training processes periodically. References Carr, W. F. (2002). Designing an effective training evaluation process.

CAUSES OF TRAFFIC DEATHS

CAUSES OF TRAFFIC DEATHS When a person gets behind the wheel of a car, it is just as if they have a loaded gun in their hand, waiving it around, pointing it at them self and everyone else around them, and just millimeters from squeezing the trigger. Just like a loaded gun, a car could easily hurt or kill the driver, the passengers, or other innocent people. According to the National Center for Injury Prevention and control there were 11,792 Caucasian females killed in unintentional motor vehicle traffic accidents in the year 1995 (Scotti 2-3). There are many factors that comply with a traffic accident. The world today has become rushed and hectic, therefore everyone is always late for something. People are so caught up in their own lives that they forget what they are doing and even where they are going sometimes. They glance up at the clock and realize that they are running a few minutes late for something important or just something in general.Congressmen visit Wilson (LOC)Without even thinking they slowl y increase their speed, not worried about what kind of accident they could cause, but worried only about what they are missing by being late.

Critically examine the text from,(Dashiell Hammett, The Maltese Essay

Critically examine the text from,(Dashiell Hammett, The Maltese Falcon, Pan) and show how it articulates concepts of gender, race and class - Essay Example The falcon turns out to be fake and the criminals are pinned by Sam Spade who have been bent on acquiring justice for his murdered partner whose wife he was having an affair with. This paper aims to provide an in-depth analysis regarding gender and class relations present in the composition if there are any. This is in line with the view that literary works mirrors society even if unconsciously. What does the text say about the people then? How did they interact with one another? What was the role of women, men and those in between? These are the questions that would be guiding the discussions. Information regarding gender issues are presented first before the analysis of the text for every gender, class and race presented. However, we would almost be dealing with gender issues because this is what isprominent in the work. This is done so you, the reader, could better appreciate the discussion involving the literary work. I would like to inform the reader to adapt a more critical view as most of the concepts here presented may seem to be far fetched. I have tried my best to argue my ideas and it would up to you whether they hold substance. In ages past, the woman was only deemed fit for household chores and the raising of children. They had no right to vote and share their views on matters concerning the family and the community nor were they allowed to vote or decide their marriages. Even today, some societies have meticulously preserved tradition on the status of Adam’s partner. To serve as objects of desire and weakness – that was their role. Nonetheless, there have been significant changes on the way society regards women. Various reforms have been made to the point that they now enjoy most of the liberties of men giving rise to the term â€Å"women empowerment†. Feminism comprises a number of social, cultural and political movements, theories and moral philosophies that are concerned with
