Atmospheric pollution

Atmospheric pollution Executive Summary Harmful gases, liquids or solids may be present in the atmosphere causing air pollution. There are however different types of pollutants of air. This paper discusses atmospheric air pollution and the resultant ecological problem, factors that lead to or that are affected by air pollution, in this regard, living and non living factors, the subsequent human impacts, considering positive and negative impacts, the current approaches taken for sustainability purposes, how such strategies may be achieved or attained, and the role of the government, society and international bodies. Introduction Air pollution is the availability of harmful substances in the atmosphere in gaseous, liquid, or solid form. Air pollution can be caused by various pollutants including: Particulate matter: this consists of aerosols in liquids, solids or gases suspended in the atmosphere due to burning of coal in industrial processes. The presence of aerosols in the air hastens the corroding and erosion of metals and building materials respectively. Inhalation of air containing particulate matter can interfere with the respiratory system of humans. This can result in cancer, asthma, bronchitis or other diseases (EPA, 2008). Sulphur oxides: these usually arise from the burning of coal and fumes from industrial processes. Due to the acid nature of the oxides, materials, human respiratory system and the vegetation end up being damaged (EPA, 2008). Carbon monoxide: this is a colourless, tasteless and odourless gas that humans have no protection against. Blood that is infiltrated with carbon monoxide carries less oxygen to other body parts. This can cause many health complications (EPA, 2008). Hydrocarbons: these are chemical compounds that contain carbon and hydrogen as the only elements. Just like carbon monoxide, hydrocarbons are also emitted by motor vehicles and emissions from industries. They result when there is partial burning of engine fuel. Under sunlight, hydro carbons form ground level ozone which is manifested in smog. Besides that, ground level ozone can irritate the eyes, damage the lungs, and cause multiple respiratory problems (EPA, 2008). Nitrogen oxides: this usually results from high temperature combustions in motor vehicles and power plants. These oxides contribute raise the acidity in the air raising precipitation and smog production. Nitrogen oxides are dangerous to humans because they cause serious illness and deaths even though the exposure to nitrogen oxides may be short (EPA, 2008). Carbon dioxide: this is a gas that is described as natural in the atmosphere. It is produced by burning substances. It is vital for living organisms. There are other air pollutants that include the following: radioactive pollutants, ammonia, chlorofluorocarbons, toxic metals (like lead, copper and cadmium) and radioactive elements. All these pose a danger to the human health (EPA, 2008). Problem Description The presence of any pollutants in the air causes air pollution. Thus, the presence of all contaminants and toxins in the atmosphere forms atmospheric pollution which is also an ecological problem. Living organisms and the entire ecosystem suffer from health and ecological problems caused by atmospheric pollution. An average person inhales 20,000 litres of air per day. By breathing, we risk taking in dangerous substances or chemicals found in the air. Air is found anywhere and everywhere. Therefore, air pollution can be found in both indoors and outdoors. Pollution of the air can cause many diseases that include; cancer, tuberculosis, emphysema, among many others. The depletion of the ozone layer causes global warming which in turn results into the melting of the icecaps in Polar Regions hence the rising of the sea levels. The air was fairly clean until the industrial revolution. With the industrial revolution, many substances stated being burnt increasing the number of pollutants in the air. The rate of air pollutio n has been on the increase since then to date resulting in the growth of the hole in ozone layer above the Antarctica. This explains why the world leaders from the G 20 are worried and calling for frequent meetings concerning the global warming (Kurylo, 2010).

Living in Small Towns is Better Essay Example | Topics and Well Written Essays - 500 words

Living in Small Towns is Better - Essay Example Peace of mind can be experienced only in small towns because they are free from such problems. The fact that people living in smaller towns live longer than people living in bigger cities was proven in Japan. In one of the studies conducted on residents of Okinawa, a small town in Japan, it was proven that these residents lived for relatively long time compared to other residents of big cities. The reason for their long life was attributed to the peaceful atmosphere that existed there. The incidence of health-related problems like stroke, caused due to nervous tensions and/or emotions, was higher in big cities due to the rushed and busy life. Living a normal life mainly requires peace of mind, which is possible through a calm lifestyle and can be found only in a small town. Secondly, smaller towns are more safe and secure to live a normal life. Instances of road traffic accidents, crimes, and thefts are much lesser in small towns compared to big cities. People can travel to any place and at any time, even after midnight, without fear. Level of safety in small towns can be assessed based upon the fact that people in small towns rarely lock their doors. Road traffic accidents are also extremely rare in small towns, probably due to less heavy-vehicle and car traffic. The number of people who use cars for traveling is very less in small towns. For these reasons, smaller towns are much safer and more secure. The third good reason for living in a small town is its much cheaper and affordable cost of living. Quoting an example of the cost of utilities, in Florida, for a two-bedroom apartment, I had to pay $150 towards electricity bill, whereas in Utah, I pay only $70 for a townhouse. There is a huge difference in the cost of real estate of a big city and a small town. A friend of mine in Los Angeles pays around $1600 for a two-bedroom apartment.

Training employees as a cashier Personal Statement

Training employees as a cashier - Personal Statement Example Furthermore; it will help determine all the benefits and costs of the training process which later allows the management to put cost as a priority during training. This targets individual employees’ performance and uses information from any employee to determine the programme that will be used for training. In this case, the employees revealed some deficiencies of the organization which triggered the fact that training could be of used to meet their performance standards. Data was gathered through questionnaire which showed that each department was to have its own training to cater for the requirements of all the employees of the company. The employees were not satisfied with the training they had received because they felt that all issues were not addressed. Task analysis starts with each employee knowing the requirement of their jobs thus comparing knowledge and skills of all the employees to know the training needs of all the employees. During the training, the job analysis based on the skills and knowledge of all the employees is determined. Employees are told his or her area of specialization and the tasks that are to be performed.Moreover, the conditions for the tasks are to be well stipulated and show the employees when and how the tasks will be performdd.the employees should know the importance of quality performance and not necessarily basing on the quantity of the job (Gupta, 6). This determines the departments that training is needed, and the conditions under which the whole trainining will be held. The HR department and the management should know the future skills needed to improve the performance of the employees. This will help them comply with the affirmative actions, and guidelines. The labor pool should be looked at critically in order for the incorporate all people regardless of gender differences to the workforce. The laws that govern the organization may sometimes dictate the needs of training, but

Ethical appraisal of a science research proposal Essay

Ethical appraisal of a science research proposal - Essay Example Blood samples will be collected from the volunteers for lymphocyte preparation and DNA extraction purposes. By collecting blood samples from volunteers who are receiving methadone replacement therapy, this study aims to determine the role of opioid receptors (i.e. ?, ? and ? ) that contributes to the mechanism of tolerance, drug resistance, and susceptibility to the drug. This study will benefit forensic toxicologists in enabling them offer a more meaningful interpretation of a blood drug concentration found in heroin abuse cases. This study will test the following hypothesis: (1) there is phenotypic inter-individual variation in the ability of UK population to maintain tolerance to heroin; (2) that this variation is a consequence of genetic polymorphism in opioid receptors; and (3) that individuals with specific genotypes have heightened sensitivity to modifying effects of methadone replacement therapy. ... To assess the contribution of methadone replacement in the patterns of opioid receptor expression, the researcher will re-measure the key receptor levels after the 6th week of methadone replacement period. Aside from identifying volunteers with responsive receptor to methadone replacement therapy, this approach will enable the researcher minimize the potential confounding effect of habitual lifestyle on phenotypically â€Å"high† and â€Å"low† expressers. Individuals with high or low levels of receptors and those with responsive phenotype will be classified under subgroups. Eventually, lymphocytes taken from the volunteers will be transformed using Epstein Barr Virus (EBV) to produce immortalized cell lines which will be use as a model system in studying the drug gene interactions that could modulate opiate receptor levels. Identification, Discussion of Ethical Issues, and Control of Ethical Issues Respect for Human Rights Among the common ethical issues that may happe n when conducting a scientific-based research study includes matters that are related to the well-being of another person. As a common rule when conducting the actual research study, the researcher should respect the rights of another person by allowing them to make their own decision whether or not to participate in this study (Iltis, 2006, p. 126; Gregory, 2003, p. 41). In line with this, Israel and Hay (2006, p. 96) explained that harm caused by research activities is often â€Å"more likely to involve psychological distress, discomfort, social disadvantage, invasion of privacy or infringement of rights more than physical injury†. Iltis (2006, p. 139) stated that â€Å"disrespect occurs when researchers violate

Independent research project Essay Example | Topics and Well Written Essays - 2750 words

Independent research project - Essay Example There are 41 languages represented in the school and the attainment of pupils on entry is very low compared with national levels, with many pupils speaking little or no English. In addition, the percentage of pupils who have learning difficulties is similar to the figures found nationally. The school offers a wide range of before- and after-school activities for pupils, their parents and the local community. The purpose of this study is to identify an area of development on attendance and punctuality of the school as they have problems with it. According to Ofsteds report dated 2004, the Dormers Wells Infants School, it contains school complaints where actions were not required. Following school representation, Ofsted decided to publish informations relating to complaints on September 1, 2006 where actions were required by Ofsted and the school. Even if there were several complaints, they did not require any action. This responsibility to give true and up to date information was changed in January 2009. The main concern of primary school teachers is the issue of pupils taking holiday during school time. The staff were confused as to when holiday time should be authorised and when it should not be authorised. In both authorities, different practices were followed. The ones interviewed believe that Circular 3/99 be rewritten, simplified and be more user friendly for better local clarification. In primary schools, everyday attendance is checked then at the end of school term, a certificate of full attendance is awarded. Teachers are also involved in visiting homes of pupils who got absent on the first day. Some teachers are confused about authorising unauthorised absence issue. All the staff did not believe that attendance should be a part of the work load agenda but they should be involved in registration process as part of their duty of care and pastoral support of pupils and parents. However, both heads and teachers worry that too little information was being shared by school and their local social services and health departments and other local services agencies (ex: Connexions, YOT providers), that has implication for Every Child Matters (Dfes, 2003). METHODOLOGY The method I used to gather data from parents regarding attendance and punctuality is give questionnaires to parents because I found this method more convenient. The significance of this method is that the researcher and respondent should not in any way have any personal involvement. They have to maintain a social distance. (Research Method p 2) Advantages of using questionnaires are: 1. Questionnaires are more objective because responses are gathered in a standardised way. 2. Informations are relatively quick to collect using a questionnaire but in some instances they can take a long time designing and analysing. 3. Information can be gathered from a large portion of a group. Returns from questionnaires are usually low and this is not often realised. But return rates can be improved if the questionnaire is delivered and responded to on time. Disadvantages of questionnaires: 1. Like the many evaluation methods, questionnaires are given after the event, so participants may forget some important issues. 2. Questionnaires a

Ontario’s Forest Accord Essay Example for Free

Ontario’s Forest Accord Essay The Ontario Forest Accord is an organized agreement of forest industry representatives, environmental community and the Ministry of Natural Resources which aims to make an acceptable approach to establish parks and some protected areas but not jeopardizing the needs of the forest industry. The Accord is under legislated protection also concerning the management of protected areas regarding its sustainability. Now, they are currently implementing â€Å"Room to Grow† policy that advances the wood production that can be allocated to parks, protected areas and forest industries. Since the Accord is aiming for environmental beauty and sustainability, they caught the attention of the tourists which gave them the idea to really put their work into good use and drastically improve tourism. The Accord has a huge responsibility on their hands having twelve percent of the forest and protected areas for which they have to manage. With their efforts, the tourism industry got more involved and productive—they have coordinated with the Accord organizers to draw up some policies in which they can make the implementation of the Accord more accepted by the public. The â€Å"Room to Grow† policy linked the two separate fields to hand-in-hand help each other for sustainability and development as well. For conservation and protection, Ecological Land Acquisition Program was launched to protect private land. This program is concerned with the transactions between the private sector and the government who wants to claim ecologically rich area. Basically, it was made to protect the habitat of species and also restrain companies of acquiring ecological lands that may help us improve our natural resources. The Ontario Forest Accord is like a relentless police that keeps on checking the government and private sector regarding their actions with natural resources. Works Cited Ontario’s Forest. (2003).
