Industrial Air Pollution In Trinidad And Tobago Environmental Sciences Essay

Industrial Air Pollution In Trinidad And Tobago Environmental Sciences Essay The contamination of the atmosphere by any toxic or radioactive gases and particulate matter as a result of human activity defines air pollution. (EMA State of the Environment Report 2000) Over the years Trinidad and Tobago has focus on industrialization developing several industrial estates but greater focus was made to the energy sectors. They current have three major energy based industrial sites. The Point Lisas industrial estate, Point a Pierre petroleum refinery and Liquefied Natural Gas plant (LNG) located in Point Fortin. Trinidad and Tobago is considered to be one of the most industrialized countries in the Commonwealth Caribbean region. We have been blessed with a vast array of natural resources ranging from oil, natural gas and asphalt to manufactured petrochemicals. Despite the fact that oil production and refining is one of our main industry, petrochemicals and to a lesser extent steel plays great importance in the company economic growth. Trinidad Tobago is worlds leading exporter of both methanol and ammonia, currently they supply the largest source of LNG is exported to the United States. Early views and realization of Air Pollution To the general public air pollution was considered to be chemical emissions and that suspension and secondary pollutants will just dissipate with the aid of the wind and rain. As the country moves into a second wave of industrialization with several proposed plans of building the next economic hotspot in the Caribbean (Invest in TT Downstream Energy), concerns has been made toward the quality of air what we live and breathe. It was only years later when technology began to play an important part in analyzing pollutants and air quality that it was realized that air pollution was just as important as water pollution. The industrial sector in Trinidad Tobago is one of the most dynamitic in the Caribbean and this is reflected in the diverse nature of its pollutants. Table 1 illustrates the numerous industry classes, commodities produced, production process and resulting in air pollutants. Map 1: Existing Proposed Energy Base Industrial Estates in Trinidad Table 1: Industry in Trinidad Tobago and air emission they emit INDUSTRY PRODUCTS SOURCES AIR POLLUTANT Petrochemical Menthol, ammonia, urea, ethanol, liquefied natural gas Fossil fuel processing, industrial processes Carbon Dioxide, Sulfur dioxide, nitrogen oxides, Carbon Monoxide Manufacturing Metals, cements, consumer products Manufacturing and extraction process, stock piling of raw materials, fossil fuel burning Carbon Dioxide, sulfur dioxide, nitrogen dioxide, nitrogen oxides, particulate matter PM (soot, dust, asbestos fibers, pesticides and metals).

Wholesale and Retail All consumer products Service station operations, truck filling stations VOC Locations of Main Industrial Sectors With industrialization comes a need for people to benefit with the high level of employment in these areas. The demographic transition cycle in Trinidad and Tobago is fairly predictive with many of the populated areas following the same paths along the industrialized map. (Map 2)In the initial stages of industrial development focus was made on establishing industries in sparsely populated areas. The intention was also to take advantage of the favorable wind direction which would direct most of the air pollutant west ward over (for the most part) approximately 5 miles of uninhabited land space and then to the Gulf, with the intension that the vegetation would be affected in a minor way during the dry season and would be assisted by run off during the rainy season. This idea inadvertently leads to another pollution problem. This proved to be a short term imitative, as these areas soon became an attractive alternative to the long commute thus encouraging the establishment of make- shift villages and shanty towns. This was also fueled by the fact that the southern and eastern main road were in close proximity to these estates. Over time these villages soon became establish resistances acquiring basic utilities and official mailing addresses. The industries were now faced with a new obstacle. They now had to focus their attention to both the environment and the neighboring population. Table 2 identifies the main industrial pollutants found in Trinidad and Tobago and its effects on both the environment and humans. Map 2: Industries and major roadways Table 2: Main Industrial Pollutants and their Adverse Health and Environment Effects POLLUTANT EFFECTS ON HUMANS EFFECTS ON THE ENVIRONMENT Carbon Monoxide- CO It is absorbed through the lungs reducing the bloods capacity to transport available oxygen to the tissues. Depending on the exposure level it produces flu like symptoms usually not recognized and may results in death There is minimum effect on the environment. Sulphur Dioxides SO2 Depending on the exposure level it can cause: cause wheezing, chest tightness and shortness of breath, respiratory illness, alterations in the lungs, it aggravates existing cardiovascular disease. When SO2 combines with water, it forms sulfuric acid, which is the main component of acid rain. When acid rain falls it can cause deforestation, acidify waterways to the detriment of aquatic life. It also corrodes building materials. Acid rain changes the physical appearance of vegetation plants metabolism impaired Nitrogen Dioxide (NO2)/Oxides of Nitrogen NOx At low levels it has minimum or no effects on human health. However high levels NO2 can cause respiratory problem, increase a persons susceptibility to, and severity of infections and asthma. It can also affect the sensory system. It is harmful to vegetation, can fade and discolor fabrics, reduce visibility. Vegetation exposure to high levels of NOx can be identified by damage to foliage, decreased growth or reduced crop yield. Volatile Organic Carbon -VOC There are no general health effects of VOC because other gases make up VOCs however some gases may be toxic and/or carcinogen. Levels of exposure and time exposed can cause damage to the liver, kidney and central nervous system. It is known to cause cancer in animals. Suspended Particulates Matters (SPM); Total suspended particles (TSP); Particulate matters. Health effects on SPM in humans depend on the particle size and concentration can cause long term exposure increases the rates of respiratory illness and symptoms. Particulates can accelerate deterioration of surface and material. It has the potential to cause modification of the climate and contributes to acid deposition. Control Strategies Physical, Managerial and Legislative to Air Pollution The visionaries of the early industries focus little on health safety and the environment and this was reflected in the level of controls initiated by the industries. Controls were mainly one dimensional and fail to focus on the holistic views of health safety and environment. Public opinion and outburst resulting from the increasing number of medical complaints and the decrease quality of agriculture produce with allegations pointing towards the emission from these industries, prompted management to use technology to assist in the establishment of more stringent controls. This technology was also instrumental in pinpointing the actual adverse effects as a result of these emissions. Physical Controls The physical control represents the processes responsible for acquisition of raw material, storage, manufacturing and distribution processes. Use of Suppression Techniques The numerous pollutants that emit daily, through smokestacks petrochemical and petroleum industries together with major health effects, force industries to reduce the pollutant at the source. One of the proven ways of reducing these pollutants is installing scrubbers and in other cases bagging houses in the emission system. The use of end -of- pipe technology is being adapted by some industries, it is used to remove already formed contaminants in the air however it is proven to be very expensive and many industries internationally would rather pay the fines for higher emission levels than use this technique. In other words it is regarded as the less of two evils. These techniques force industries to adopt generic prevention strategies and solutions, only resorting to the more expensive techniques when face with dire consequences. Environmental Friendly Process With increasing pressure from environmental activists calling for industries to be more sensitive towards the environment, many industries have restructured their processes whereby recycling waste material as a new raw material to produce a second product. This process has been adapted by Methanol Holding Trinidad Limited (MHTL) were they have constructed an AUM plant. This plant is the first of its kind in Trinidad and Tobago being the most environmental friendly of the MHTL family. This plant comprises a diversified petrochemical complex to manufacture Urea Ammonia Nitrate (UAN) and Melamine using feedstock from integrated urea and ammonia plants. (MHTL) The local cement factory adopted several controls strategies to deal with the air pollution problem within its manufacturing process. A change from blasting to stripping of the main raw material (limestone) aided in the reduction of dust emissions that was affecting the neighboring community at their quarrying central Trinidad. The transportation of the limestone was also change from dry to wet thus also reducing the potential dust particles entering the atmosphere during transportation from quarrying to the process plant. At the out skirts of the processing plant itself major landscaping was done to create hills around the factory adorned by buffer trees with sole intension is to reduce the level of dust exposure to the neighboring community. Managerial Controls Self Regulation These controls consist of policies, systems and standards that govern and manage the organization. The establishments of the Key Performance Indicators (KPI) help management keep focus in order to sustain established targets. Company policies and procedures acts as guidelines to maintain order and structure within the organization. The introduction of ISO standards advertises the companys procedures to the industrial world thus ensuring that whatever measures initially introduced are sustained by the certification audits conducted annually by an international process auditors. Legislative Controls Currently in TT there is no legislation that refers directly to controlling of air pollutant emitted by industries. This is merely due to the fact that early monitoring system generally focus on water and land pollution the understanding of air pollution did not produce tangible evident because of technological short falls. The existing legislation addresses non specific air pollutants like the Petroleum Act (rev. 1980) section 29 (1) (j) prevention of air pollution and the Public health ordinance (1950), section 70 (1) (m) prohibits blacks smoke from chimneys. Even though the EMA was establish and is the countrys sole environmental body responsible for managing, regulating and coordinating environmental matters. The EMA has only managed to draft the Air Pollution Rules 2001 however to date 2010 these rules have not been made law. Trinidad and Tobago being a member of the Commonwealth and the United Nations has benefited from the research and technological advancement from these more developed countries (MDC). Initiatives such as the Montreal Protocol (1989 the control of CFCs) and the Kyoto Protocol (1997 the reduction of Greenhouse Gases) assisted the legislative process of TT by association. The only way legislative was establish was by piggy backing on the achievement of the more developed countries it seems that this was the only way the law maker could have had any impact on defaulters of air pollution in Trinidad. Only when legislation is pass the country can benefit from some effective control measures where polluters are prosecuted and emission limits are set for all industries. Conclusion Trinidad and Tobago historically is a nation of followers there have been very few instances where we were not promoted or assisted in some way or the other in achieving established goals and the topic of pollution is no exception. Have we ever wonder why the one establish air pollution laws stems from a diplomatic relations within the commonwealth and the United Nations or why we had to wait until the advent of OSHA to enforce existing safety laws in our country. The answer is simple we are still waiting to follow no wonder legislation spear headed by locals are treated with scan courtesy. Had these laws been establish in some first world convention they would have been rooted in the seams of our judicial system years ago? Many of the existing pollution laws governing the more develop countries were mainly as a result of international pressure, sadly Trinidad and Tobago is not view as a major polluting nation because of its geographical location and size. Evidence of pollution aware ness is mainly seen in the new establish manufacturing countries whose parent companies originate overseas. It is only amongst of fellow less develops countries and Caribbean members that Trinidad and Tobago is recognize as a polluting nation sadly these countries have little impact on global view. Despite our shortcomings, internally there has been an intensified effort to effectively monitor record, control and enforce pollution reducing systems and strategies. Internationally the over site of Trinidad and Tobago (a country that can easily fit into the Orinoco River with a population that barely exceeds large town in the United States) has not deterred local efforts to manage the levels of air emissions.

New and Improved? : The processes of globalisation on spiritual practic

New and Improved? : The processes of globalisation on spiritual practices; illustrated by the global spread of Reiki. The processes of globalisation create an open market place for trade, but globalisation is also an exchange of cultures, of ideas and practices. Spiritual practices and rituals are one of the ways in which a culture reproduces itself and as such, is subject to hegemonic forces which act to alter the existing form. It has been said that Globalisation may be regarded as a threat to regionalized spiritual practices because there is a tendency to standardise them in an Americanised form, which is primarily Christian. One of the under explored aspects of the Internet is the cultural effects created by the exchange of spiritual ideas and practices online. As more people gain access to the World Wide Web, the diversity of spiritual information available increases exponentially. Exotic cultural practices, once only available to the privileged few who could afford to travel to exotic locations, is now available to millions of people across the globe, at the touch of a button. Gone are the days when spiritual practices are linked to a specific geographical area, with religions linked intimately to the histories and cultures of respective nations and ethnic groups. Spiritual rituals are undergoing a deterritorialisation, aided by new media. It has been suggested that the activities of individual religious groups will be increasingly characteristic of free competition on a global scale. Religion has always been a globalising phenomenon, with missionaries and pilgrims travelling to spread their version of the ‘Word’ to the unenlightened. According to Peter Beyer, â€Å"In the context of globalisation, all religions are increasingly under pressure to see themselves as universal in principle, whether historically they have or not.† Religions that have travelled across the globe have been spread, throughout history, by a network of the ‘Faithful’ leaving their home community, forming new communities as they travel, preaching and teaching their messages and rituals to their converts. Now these networks may be built and maintained electronically. As the printing press made the bible and religious texts available to the masses rather than just the clergy, so the Internet has given people the means to access spiritual information from other cultures and regions... ...pick=67 accessed 10/1/05 BEY, Hakim, The Information War, http://www.ctheory.net/text_file.asp?pick=64 accessed 10/1/05 http://www.ctheory.net/text_file.asp?pick=82 accessed 10/1/05 http://www.gseis.ucla.edu/faculty/kellner/essays/globalizationtechnopolitics.pdf accessed 10/1/05 http://www.mbay.net/~jmejia/book063.htm accessed 10/1/05 http://www.reikihealingpower.com/learn_reiki.htm accessed 10/1/05 INOUE, Nobutaka, 1997, 2001 The Information Age and the Globalization of Religion, http://www2.kokugakuin.ac.jp/ijcc/wp/global/06inoue2.html accessed 10/1/05 MILUTIS, Joe, Making the World Safe for Fashionable Philosophy! http://www.ctheory.net/text_file.asp?pick=390 accessed 10/1/05 ROBERTSON, Roland, Comments on the "Global Triad" and "Glocalization" http://www2.kokugakuin.ac.jp/ijcc/wp/global/15robertson.html accessed 9/1/05 SHIELDS, Rob, The Virtual, London and New York: Routledge, 2003, Reviewed by KELLNER, D., and Thomas, A. http://www.gseis.ucla.edu/faculty/kellner/essays/reviewthevirtual.pdf accessed 23/12/04 THIEME, Richard, Entering Sacred Digital Space: Seeking to Distinguish the Dreamer and the Dream, http://www.thiemeworks.com/ accessed 23/12/04

Bringing the constitutional presidency to life

The constitutional president in the United States of America is the president who has been elected by the citizens of the republic on majority votes. Bringing to the constitutional presidency to life is bringing the custom of electing presidents who would lead the country according to the constitution. Constitutional presidency The constitutional president leads the country in accordance to the powers that he has been given by the constitution and has a duty to lead the cabinet businesses.The president is the overall leader of the country is therefore responsible of hiring and firing cabinet. A constitutional president get to the position of presidency after the voting process has taken place as has been dictated by the constitution. No one has powers to ruin the presidents powers, may it be the civil or religion leaders. The president may use the religious believes of the country’s customs to dictate the undelegated power as he should understand the law of God and the law of nature in order to help him make such decisions.A constitutional president may make decisions of his freewill without consulting the delegates, such decisions may include amnesty of some petty crime victims and authorization of a bill to be passed as law for that to be a custom of the country in favor of the society. A constitution president is allowed to vie for the seat as many times as the constitution would allow him, he runs for a given number of times in which he shall not exceed if the constitution does not allow.

Free Essays on Iphigenia And Today

Our society isn’t much different from the society of the Greeks. In many ways, we are just like them. News stories are given to us in a format much like that of an ancient epic. We are given the meat of the story before we even know how the conflict started, and we are later given the outcome. We can see this in the case of the World Trade Center attacks. We awoke to hear the news of the towers being attacked, but it wasn’t until much later that we found out how and why. We still have yet to hear the end of that story, and I believe it will be quite a while yet before we do. Also, much like the Greeks, we, as Americans, believe we are the best country in the world. Until September 11th, we thought we were untouchable, and now we know we are untouchable as our government tightens our boarders and begins to regulate our means of travel. This is because of our recent â€Å"Trojan Horse:† the men who hijacked the planes were all living within the US. This had made ma ny people wander if we are too easy on foreigners who wish to enter our borders. If the Trojans would have been less allowing with what came through their walls, we might not have to think of them in terms of mythology. While Troy’s lack of forethought was good for the Greeks, it is still a loss for those of us who would have liked to know more about Troy’s past culture. While we resemble the Greeks in many ways, we still need to catch up to them in a few important things. Yes, I said we, not them.

Optical fibers can be used to guide lightwhich is electromagnetic radiation in a certain frequency rangein much the same way that metal wave guides or coaxial cables can be used to guide lower-frequency electromagnetic radiation. An optical fiber is usually circular in cross section and consists of a core and cladding. An optical fiber for communication applications is typically between about 0.1 and 0.2mm (0.004 and 0.008 in) in diameter. In order that the light waves be guided by the fiber, the core must have a higher index of refraction than the cladding. One such fiber is called a step-index fiber because the index changes abruptly at the interface between the core and the cladding. An important variation of this structure is the graded-index fiber, so called because the index of refraction decreases smoothly outward from the In the step-index fiber, the light wave is guided by a process called total internal reflection. Only rays that have an angle of incidence at the core-cladding interface greater than the critical angle will be reflected back into the core and thus guided by the fiber. Some rays follow a longer path through the fiber than do others. Thus a pulse of energy entering the fiber undergoes dispersion. This effect limits the bandwidth of the fiber and reduces the amount of information it can transmit. This undesirable feature can be partly overcome by the use of graded-index fibers of proper design. Fiber optics is used in several areas of telecommunications. Advantages of optical fibers include their wide bandwidth, low attenuation, lightness, smal ...

Bells Palsy Medical Report Essay Example | Topics and Well Written Essays - 250 words

Bells Palsy Medical Report - Essay Example Displacement of the mouth towards the unaffected side is also apparent. The patient may have difficulty closing his eyelids too hence it is very important to provide eye care to protect the cornea (Stein, & Miller, 2000). Pain behind the ear is also present. Interestingly, the patient may also experience crocodile tears, an excessive eye tearing on the onset of the disorder and at the time of recovery especially during chewing. Physical examination includes determination of muscle weakness. The physician may ask the patient to lift and lower eyebrows, tightly closing and opening of eyelids, and smiling to the ears. Although, a patient may be diagnosed with presenting muscle weakness, diagnostic tests like MRI, CT scan, electromyography (EMG), and nerve conduction velocity (NCV) are still required to rule out other underlying causes and illnesses. The cause of Bell’s palsy is unknown but it is believed to be preceded by respiratory infection like influenza and common colds. Diabetes is less likely a cause. A possible culprit is a viral agent particularly herpes simplex. This makes it possible to treat the disorder with corticosteroid drugs such as prednisone and dexamethasone together with acyclovir, an antiviral

Political science as the discipline Essay Example | Topics and Well Written Essays - 250 words

Political science as the discipline - Essay Example The present research has identified that in the inaugural term, the structure of governance in the United States is examined by exploring the Constitution and the fundamental idea of the separation of powers. Once this foundation is laid, students learn about the importance of elections particularly focusing on the Congressional elections, Presidential elections, the role of the Electoral College and the gerrymandering of Congressional districts. The class undertakes to provide an in-depth exploration of the interactions between Congress and the President specifically on issues around gridlock, public opinion, and the media. This essay discusses that having examined how laws are made in the first semester; the second semester begins by exploring how laws are carried out by the bureaucracy as well as how such laws may bring the federal government into conflict with state governments. The researcher states that attention is switched to the role of the judiciary, where the students exam ine the influence of the Supreme Court on the American political process with special attention devoted to issues surrounding civil liberties and civil rights. This paper illustrates that during this duration, the student’s time is mostly devoted to investigating foreign policy in the context of the current challenges confronting the United States, as well as long-term debates surrounding exceptionalism and declinism.
