Research Project: Impact and Causes of Air Pollution

Research Project: Impact and Causes of Air Pollution NATIONAL DEVELOPMENT AND GLOBAL EMPOWERMENT, THE CASE OF INDUSTRIAL AIR POLLUTION IN ILUPEJU INDUSTRIAL ESTATE, LAGOS STATE. BY ATUBI AUGUSTUS O. (Ph.D) ABSTRACT The research work is primarily on industrial pollution; focusing on air pollution in the Ilupeju industrial estate of Lagos State, in Mushin Local Government Area. Air pollution has been a serious problem to the people who reside closely to Ilupeju industrial zone since inception of the area. It has been responsible for various ailments among the people and those who work in the industries that pollute the air through the use of some dangerous chemicals. The research work looked at the various ways by which air pollution is being generated in the area, the effects on the people and the possible control measures to minimize its further damage on the health of the people and the place for national development and global empowerment. INTRODUCTION The environment is the setting of man’s various productive activities. The impact of man on the landscape through these activities and the extent of environmental pollution arising there from have been well documented (Atubi and Onokala, 2006a, Atubi, 2007b). In Nigeria today, most of the industrial estates are not meant for industries alone; residential homes can be found in the so-called industrial estates also. And with this development, the problem of industrial pollution has effects on man, plants and materials. The areas which contain industries manufacturing different products such as petrochemicals, detergents, injects harmful wastes into the air such as carbon monoxide, sulphur oxide, nitrogen oxide and hydrocarbons which are the major sources of air pollution. Generally, the release of industrial waste into the air has been responsible for many health problems such as chronic bronchitis, malaria, asthma and also the damaging of roofing sheets and buildings. The resident are not fully aware of the damages being done to their lives and properties by those harmful wastes. Most of the past researches in Nigeria and the world in general on industrial pollution such as Hodges (1977); Mcgraw-Hill (1977); Okoro (1979); Nwafor (1981); Simmon (1982); Kormondy (1984); Segynola (1988); Ohagi (1988); Ademorati (1988); Miller (1994); Hill (1999) to mention a few, have their focus on effects and causes of industrial pollution in general and not on industrial estate. Available evidence (Census, 1991) shows that about sixty thousand people reside in the Ilupeju industrial area, yet very low priority is accorded to the problems of industrial pollution and environmental quality in the area. The problem of air pollution is worse in Lagos than in any other Nigerian city. It is also more complex in Lagos. The study is aimed at analyzing the effects of industrial air pollution on the residents and environments of Ilupeju industrial estate as a way for national development and global empowerment. STUDY AREA/DATA COLLECTION This study is focused on Ilupeju industrial estate, which in the context of this paper comprises of over 20 streets and for proper administration it was further divided into three zones. The zones are Ilupeju bye-pass as zone A, Coker area as zone B, Town Planning area as zone C. Ilupeju industrial estate is located within the Mushin Local Government Area of Lagos State. It covers an area of about 110 hectares of land. It is transversed by longitude 30 and 3060I east and latitude 3030I north. It is bounded in the North by Ikeja Local Government Area, in the east by Somolu Local Government Area, in the West by Oshodi/Isolo Local Government Area, and in the South by Surulere Local Government Area in Lagos State in 1962 (fig. 1). It occupies a unique position in Lagos State, firstly as an industrial zone, secondly as a commercial centre, thirdly as a residential area and lastly as a major route. The concentration of industries can be found in Ilupeju industrial estate. And the area is well established because of the rapid growth of new and large industrial establishments, which include good transportation, and relatively high standard of available public utilities. The industries on this estate include paints, plastic, textiles, printing services and the manufacturers of soap and detergents etc. The banking sector is another sector found amongst the economic activities that takes place in Ilupeju. The data on which the study is based were collected through questionnaire survey in the year 2005 from three zones to which Ilupeju industrial estate was divided. The random/systematic sampling techniques was used to select a number of streets. Out of the 20 streets in the area 10 were randomly selected for the study in which three houses were again selected randomly with two persons selected for interview. Responses from the questionnaires were mainly used for data analysis. The computation elied on averaging model, percentages and Analysis of variance (ANOVA). CAUSES OF INDUSTRIAL POLLUTION Mcgraw-Hill (1977) stated that other sources such as pesticides and man’s earth-moving and agricultural practices lead to vastly increased atmospheric burden of the soil particles and of pollens, spots, rust and smuts. Okoro (1979) further stated that industrialization is as a result of man’s attempt to provide himself with facilities for optimum employment. Industries leave behind peculiar wastes. They also pollute our environment, think of the cloud of smoke that emerges from the industrial house and apparently disappears into the air, think of various colour liquid some of them have foul smells that are emptied into the rivers, lagoons and oceans. They change environment’s composition and destroy its purity. To assess this, respondents were asked to mention the causes of industrial pollution in the estate. The response made showed that the use of chemicals in Zone A is one of the major causes of pollution in the area followed by the release of smoke from the industries which 24 people responded to it, while the poor disposal of waste and noise from machineries have responses of 23 and 20 respectively. In zone B, 19 people responded to the use of chemicals, 10 to the poor disposal of waste, 9 people indicated to the noise from machineries and 15 responded to the release of smokes from industries. Finally, in zone C, 20 people indicated that the use of chemicals is the major cause of industrial pollution. 18 responded to the poor disposal of waste, 17 to noise from the machineries, and 18 to the release of smokes. Table 1 shows the details. From the table it could seen that zone A and C had high indications than B, this is because Zone A and C are the nearest neighbours to different industries while zone B are area away from the industries. TABLE 1:THE CAUSES OF INDUSTRIAL AIR POLLUTION IN ILUPEJU INDUSTRIAL ESTATE. Source: Field Survey, 2005 Therefore, the major causes of industrial air pollution as seen from the table is because of the use of chemicals which in turn pollute the area through the release of smoke. TABLE 2:THE EFFECTS OF INDUSTRIAL AIR POLLUTION IN ILUPEJU INDUSTRIAL ESTATE Source: Field Survey, 2005 Table 2 shows that in zone A 20 indicated that restlessness has been one of the effects of industrial air pollution followed by persistent cough and chest pain, eye irritation which is the highest with 21 responses and 20 for asthmatic patients. Zone B, as could be seen from the table 2 had eye patient with 20 respondents and 10 respondents respectively for restlessness and persistent cough and chest pain. Zone C showed that the effect of industrial air pollution is more on eye irritation and persistent cough and chest pain with 20 respondents respectively while restlessness had the highest respondents and asthmatic patient has 19 respondents. From the above table 2, the effects of industrial air pollution is felt more in Zone A followed by Zone B and this is because the residential areas are nearest to the industrial area. Zone B has a total of 59 compared to Zone A (81) and Zone C (80). From the table it indicated that zones A and B have the highest effects of industrial pollution than zone C. Hypotheses were formulated and tested using analysis of variance statistic. The calculated values are 10.27 and 3.72 and the critical table value are 4.26 and 4.26. Therefore, there is variation of industrial air pollution in Ilupeju industrial estate. (See Appendix 1 and 2 for necessary computations). POLICY IMPLEMENTATION In order to prevent severe health hazards arising from increased industrial activities which pollutes the environment, government’s silence on environmental protection over the years should be broken and public interest must be sufficiently aroused through documentaries and corrective measures of pollution. We should therefore, plan ahead, and learn from the mistakes of the industrialized nations and their current efforts to correct those mistakes. We should not allow pollution to be the price of the state’s progress. The establishment of some parastatals concerned with the maintenance of sanity in environment is the next step in the right direction. The Lagos State Ministry of Environment, Lagos State Environmental Protection Agency, Federal Environmental Protection Agency and the Ministry of Health, etc. amongst others are charged with the responsibility of protecting the environment and maintaining a healthy environments as a way for national development and global employment. However, to grapple effectively with our environmental problems and enhance the quality of life in our settlements, we require information in the nature and dimension of these problems. The State Government should make funds available for relevant research to increase our understanding of the source and effect of gaseous pollutant and all disciplines have a role to play in this regard. There is need to design relatively, cheap yet efficient methods of waste disposal for our towns and cities (Atubi and Oriero, 2006b). Finally, it may be observed that in the area of pollution control, there must be a good deal of cooperation between professionals. The engineers should explore different alternatives of controls; the economists must determine which combination of measures is least costly for a given degree or control. The social scientists explore the intangible benefits associated with different level of control, the surveyors to determine how best each level of control could be developed and the jurist establish how different control measures can be enforced. The decision regarding the control measures can be adopted and enforced. However, the adoptions rest with the people and the government. They will have to pay for it and will have to live with it. CONCLUSION The result of the study has shown that all environmental pollution in Ilupeju industrial estate is created by man’s activities in living, producing and consuming goods and services. These activities generate net benefits to the people undertaking them even though they may impose unwanted cost. An important objective of environmental resources management in Lagos State is to plan towards an improvement of overall quality of the state’s human environment and this plan should be undertaken from the local level upwards. To achieve this objective, a strategy should be worked out to ensure that the use of resources for the welfare of man does not result in a conflict between the environment and development or between resource utilization and man.

Julius Caesar Essay: Superstition in Julius Caesar :: Julius Caesar Essays

Julius Caesar: Superstition In the play of Julius Caesar, we see a brief picture of Roman life during the time of the First Triumvirate. In this snap shot, we see many unfortunate things. Shakespeare gives us the idea that many people try to circumvent what the future holds, such as unfortunate things, by being superstitious. Superstition seems to play a role in the basic daily life of most Roman citizens. The setting of the first scene is based upon superstition, the Feast of Lupercal. This feast is in honor of the god Pan, the queen of fertility. During this time, infertile females are supposed to be able to procreate, and fertile ones are supposed to be able to bear more. It is also a supposed time of sexual glorification and happiness. Other scenes depict how throughout Rome, roaming the streets are mysterious sooth-sayers, who are supposedly given the power to predict the future. Dictating what is to come through terse tidbits, these people may also be looked upon as superstitious. In the opening scene, one sooth-sayer, old in his years, warns Caesar to "Beware the Ides of March," an admonition of Caesar's impending death. Although sooth-sayers are looked upon by many as insane out of touch lower classmen, a good deal of them, obviously including the sayer Caesar encountered, are indeed right on the mark. Since they lack any formal office or shop, and they predict forthcomings wi thout fee, one can see quite easily why citizens would distrust their predictions. Superstition, in general elements such as the Feast of Lupercal, as well as on a personal level such as with the sooth-sayers, is an important factor in determining the events and the outcome of Julius Caesar, a significant force throughout the entire course of the play. As the play develops we see a few of signs of Caesar's tragic end. Aside from the sooth-sayer's warning, we also see another sign during Caesar's visit with the Augerers, the latter day "psychics". They find "No heart in the beast", which they interpret as advice to Caesar that he should remain at home. Ceasar brushes it off and thinks of it as a rebuke from the gods, meaning that he is a coward if he does not go out, and so he dismisses the wise advice as hearsay. However, the next morning, his wife Calphurnia wakes up frightened due to a horrible nightmare.

Leadership Essay

Vice Principal Mr. Leonard Curry entered the main staffing office of the Academy and ordered a young teacher to get out into her class. Her quiet gentle response was, ‘I do not have a class now, sir.† â€Å"What!’ was his rebuttal insisting that the schedule had been changed and it was her period to be teaching a 10th grader’s Biology class. She replied by asking if it were ethical for her to be informed in such a manner pointing out that   a memo is the acceptable mode of transmitting such changes. This was followed by a gentle explanation she wanted to perform her duties without conflict. Further he said that it was her responsibility to check out changes on the teacher’s assignment notice board from time to time. She reiterated that that was an unconstitutional approach since it was not stated like that in the bylaws of the school. They continued to argue with the principal threatening her with suspension for insubordination had she not complied. A disciplinary report was eventually filed for insubordination and disobeying the rule of law. Impact on credibility—Principal-Mr.Cury displayed a tendency towards an autocratic leadership style. Once how to address the issue was lawful inscribed in the bylaws stipulating a particular way to inform about staffing changes it had to be adhered to. It would appear that the young teacher reminding him of it antagonized the situation. This is a challenge to his credibility. Communication-It is clear that there was a change of command in terms of communication. The principal seemed to have erred. His reaction is to blame the young teacher for his mistake by imposing a penalty on her for his mistake. This is often a management strategic adopted in a autocratic culture. Power of influence—in this situation the power of influence lay in the position or status of principal. The principal used it to make himself look respectable while casting blame onto unsuspecting immature teacher.

Analysis Of CisnerosThe House On Mango Street - 742 Words

â€Å"To know anothers heart, you must first know your own.† (Laurrel K. Hamilton) Throughout the many vignettes, indirect characterization, vivid imagery and eloquent metaphors are utilized in many ways to create a connection between the characters and the reader. These characters explore sexuality, gender, culture, ethnicity and many more crucial things that are all a part of growing up and figuring out who you are. In Cisneros’ The House on Mango Street the identity of a character is made up of the environment they are a part of. Gender is one of the most important things that can build up ones true identity. In Mango Street, we see a complete male ruled society. Sexual harassment, from men, is very common in this story, especially to†¦show more content†¦They laugh and poke fun at her but that’s not the worst of it. Her parents named Esperanza after her grandmother, which should be an honor, yet not to her. She compares her grandmother to the other women she sees on Mango Street like Mamacita who â€Å"sits all day by the window and plays the Spanish radio shows† (77). Esperanza is afraid to become submissive to a man or a society that oppresses women, like the one she lives in currently. These have a link to the comparison of Esperanza and her family in relation to the 4 trees. The female role models in her life are all she knows and cannot just forget them easily. â€Å"never quit their anger. This is how they keep.† (74) She will always have her roots planted in Mango, and sh e can’t change that, which is why it is part of building her identity. Esperanza had a great desire to live elsewhere, in â€Å"A real house.†(5) While not realizing it then, she had an out from the hardships of living on Mango. Esperanza wrote and wrote to dealwith what she dealt with. â€Å"You must keep writing. It will keep you free,†(61) In time she figures out that some people don’t have a way to manage what they go through. Esperanza’s mother has a coping method also, and it’s drawing; with a needle. â€Å"She draws with a needle and thread.†(90) The realization that she is lucky enough to be able to handle Mango street and it’s quirks builds character in Esperanza. She is able to appreciate what she has, yet it is also saddening to know that some are not as
