ABSTRACT
A review of Gas flaring activities in Niger Delta Area of Nigeria was carefully studied for period of 24 years. Result of the study suggest that while the people of the Niger Delta region may have benefited from oil and gas exploration, the adverse economic, environmental health, social urbanization impacts of the operations out weight the benefits. Oil and gas exploration and exploitation is one of the major reasons the atmosphere, land and sea as well as life’s and plant therein are clearly being disturb. The data for the area (70,000Km2) and population were collected from National population commission (NPC 2006) that of temperature records from 1989-20012 (Niger Delta Region) were collected from Nigeria Meteorological Agency (NIMET) data for gas production, utilization total flares, export and domestic consumption in barrels were collected from petroleum corporation (NNPC).
Base on the data, descriptive analysis, multiple bar chart, pie chart, histogram and trend analysis {analysis of variance-SPSS) was used to show the grow and decline of oil spillage in Niger Delta with a high standard error 293.567. The trend analysis shows the equation
y = 492x – 2061 and the correlation of R2 = 0.131. The bar chart in fig. 3 recorded Nigeria as
the highest in flaring of gas production among the comparism countries indicated in table 3.
The results revealed that environmental pollution due to heat radiation from gas flaring stations in the Niger-Delta area of Nigeria has been identified as one of the major causes of temperature change which lead to an increase in the effective temperature of the Earth. Advice on how Nigeria (Niger Delta will reduce gas flaring is included).
Keywords: Gas flaring, Temperature, Niger Delta, crude oil.

INTRODUCTION
The Niger Delta covers a field of about 70,000 Km2 and 20,000 km2 within wetlands formed primarily by sediment deposition, which houses Nigeria’s proven gas reserves, estimated to be 120 trillion cubic feet (Onyiah, 2005). Homes of 20 million people and 40 different ethnic groups, this flood plain makes up 7.5% of Nigeria’s total land mass. It is the largest wetland and maintains the third-largest drainage in Africa. It has 5.3610N and
6.7080E.However, while the exploitation and exploration of oil has created some fortunes and
contributed positively to the economic and technological advancement of Nigeria as a whole, the accompanying socio-economic and ecological fallout remain problematic (Akpan 2009).
In Nigeria, burning off the associated gas (AG) has been illegal since 1984 and the Nigerian government has set up several deadlines to end the practice, but gas flaring continues till date. According to 2005 friends of the earth report, about 2.5 billion cubic feet of gas associated with crude oil is flared in this way everyday. This is equal to 40% of all African natural gas consumption in 2011 and represents a financial loss to Nigeria of about
2.5 billion USD. The flares have contributed large volumes of green house gases than all of sub Saharan Africa combined as well as several dangerous toxin released into the atmosphere, polluting the soil and thereby affecting the health and well being of the nearby Niger Delta communities, exposing the residents to an increased risk of premature death respiratory illnesses such as Asthora and cancers. The public considers the oil-producing companies operating in the Niger Delta companies responsible for polluting the environment by way or relentless flaring and venting of gas into the environment, heat radiation, noise radiation, oil spillage, water pollution, site clearing, deforestation and destruction of the flora and fauna and consequences disturbances of the ecosystem in the 70,000 square kilometers of
Niger Delta wetland (Ifeanyichukwu, 2001).

Obi et al (2008) pointed out that the total number of incidents of oil spillage from
1976 to 2005 was 9092 in line with table 1 of Nwilo et al 2005). These is a major source of climate change which is creating increased uncertainty about the future temperature and precipitation regimes which makes investments in agriculture and other weather – dependent livelihoods inherent more risky (FAO, 2008).
Ewona et al (2012) in line with (Lohman 2006) suggested that climate is closely associated with the burning of oil, coal or gas. They also pointed out that, one important feature observed in the region is the almost complete absence of primary forests except perhaps in CrossRiverState where conservation efforts by both federal and state governments have left a stretch of rainforest. This has been attributed to climate change in part and mainly due to human activities in the other hand.
According to IPCC (2007), refer to climate changes as “change in modern climate which are 90-95% likely to have been in part caused by human action. Climate change is defined as a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is addition to natural climate variability observed over comparable time period”. (Unite Nations Framework Convention on Climate change (UNFCCC, 1992).
Uncontrolled logging, agricultural activities, acid rain, oil exploration and exploitation, urbanization and mining activities have contributed immensely to lose of vegetation. Ewona, et al ( 2012) which is one of the major contributor to the climate change.
In line with Udo et al (1999) , Udo et al (2008) and Ewona et al (2010) emphasized that no two climate can be exactly the same. However, similar or close the two locations may be geographically. The World Health Organization advised that Nigerian government should address the problem of gas flaring by paying close attention to the activities of companies
engaged in flaring and the environmental problems associated with their exploratory methods

and to invite experts from developed countries to work with Nigeria professional and environmentalist to proffer remedy (Global gas reduction initiative, 2002: world bank report,
2004). Abdukareem, et al (2012) noted that, in spite of advances in technology and the potential to convert the flared gas into a source of enormous nation revenue, the practices has continued in Nigeria, Ostensibly underscoring the problems of our national development Akpan, (2009). combustion of associated gas during flaring also releases heat into the environment. The heat radiation from gas flaring greatly affects the surrounding environment and particular crops planted within the vicinity of gas flare stations Abdulkareem and Odigure, (2002).
According to the United states Environment Protection Agency (U.S. EPA) “many scientific studies have linked breathing particulate matter to a series of significant health problems including aggravated asthma, increases in respiratory symptoms like coupling and difficult or painful breathing, chronic bronchitis, decreased lung function and premature death.“it has also accepted that exposure to benzene and its metabolities causes acute nonlymphocyticleuvemia and a variety of other blood-related disorders in humans.
Udoimuk and Udo (2002) suggested that since emphases is laid on environmental problems, the need for a major shift to a global energy system based on high level of energy efficiency world wide and rapid growing role for renewable energy is paramount. The basic sources of oil pollution at the coastal waters of the Republic of Nigeria are accidents at the extracting platforms, accidents by tankers transporting crude or refined oil pipelines. All these lead to an increase in the counter radiation which increases the average temperature of the earth.
POLLUTION
Pollution is a term that defines any environmental state or manifestation which is harmful or unpleasant to life, it can also be defined as the introduction of natural and artificial

caused due to man’s failure to achieve control over the physical, chemical, or biological consequences or side effects of his scientific industrial and social habit, Drake and Hubacek, (2007). Industrial source of pollution is a result of release of hazardous waste and huge mass of unclear gases and other airborne particles produced as by-products in process industries. The degree of the increase of process industries is increasing drastically, this improvement as change man’s way of life remarkably, however the advantage derived have not being without a price which is basically the effect of pollution on the environment, Carvalho et al., (2005); Pollutants are emitted into the atmosphere as either or particles, and are eventually removed by natural self cleansing processes Ajayi, (1999), Alameddine (2009) and El-Fadel, (2005) The waste mostly originates from the burning of fossil fuels and the processing of materials by industries Abdulkareem et al., (2011). Other sources include waste from burning engines in cars, fuel use in domestic sectors, oil boom, gas flaring, agriculture processes, but of all these the process industries have been recognized as the major source of air pollutants. So much damage is being done to the environment through gas flaring, that if nothing is done in a few years from now, serious environmental and health problems such as premature death and diseases will emerge with respect to gas flaring, its effect on vegetation, health and the micro-climate are equal searing. Apart from the noise produce from the fire at the flare sites, the thick rain and eventually poison streams, lakes, lagoons and rivers thereby destroying aquatic organism and making the water unhealthy for drinking. It has been proven that gas flaring generates heat which is felt over an Average radius of 0.5 kilometres thereby causing thermal pollution (Ikelegbe, 1993). Gas flaring cause green house effect, thereby producing global warming and green house gases which include: water vapour, carbon dioxide, Methane, nitrous oxide; ozone, carbon monoxide and nitrogen oxide, Indriani, (2005);
Nwaichi and Uzabona, (2011).

The fear of the known “unknown” environmental pollution has transcended natural boundaries stratospheric ozone depletion, global warming, the green house effect, deforestation, acid train and mega disaster are some of the various environmental problems associated to pollution. The potential effects of global pollution have necessitated global cooperation in other to secure and maintain a liveable global environment (Odjugo, 2010). It has been reported that pollutants emitted from one country can easily cross political boundaries. People are beginning to recognize that pollutants can affect not just a region but the entire planets. As the excess C02 rises into the atmosphere, it acts as absorptive body, which trap heat reflected from the earth surface. Scientists accept that green house effect from increased level of C02 and other heat trapping gasses eventually will cause an increase in global temperature. Some predicted that the temperature will rise significantly within the next century and that global pattern could be drastically disrupted. Air pollution is not restricted to outdoor air, although relatively little attention is given to the hazards of many substances found in indoor air most especially in the developing nations where there is no proper regulation in place to combat air pollution. But it is however well established that people may spend as much as 80-90% of their time indoor. The sources of indoor pollution are different for developing and industrialized country,Odigure and Abdulkareem, (2011). In developing countries, indoor pollution comes mainly from using biomass fuels (Wood, agricultural waste, dung etc.) for cooking and heating. The majority of the world’s population depends on biomass for most of their energy supply. It is estimated that 400-500 million people mainly in the rural area of developing countries and primarily women and children may be adversely affected by indoor pollution (FEPA Rapport, 1998). The fuel is burnt inefficiently in rooms that are poorly ventilated. Biomass smoke contains numerous substances, the most hazardous of which include suspended particulate matter, nitrogen
dioxide, carbon dioxide, and sulphur dioxide (Gwendolyn et al, 1993). It also releases a

number of adehyde. While the key indoor pollutants in an industrialized countries are nitrogen dioxide, carbon monoxide, radon (from building material), formaldehyde (from insulator, asbestos, mercury, manmade fibers etc. Also polluting the environment is the heat radiated as result of these indoor activities and process industries. The released may be harmful to plant and animal. In Nigerian context, gas flaring from the oil exploitation and exploration in the Niger-Delta area of the country has been considered as the major sources of environmental pollution. Every day in southern Nigeria, almost 2million cubic feet of natural gas is burnt (flared) during crude oil production, more than is flared anywhere else in the world (Oni and Oyewo, 2011). Hence, gas flaring is not only waste of valuable resources, but is also a major cause of environment pollution in the Niger-Delta, where most of Nigeria’s oil output is produced. Nigeria has a population of over 170 million people and an abundance of natural resources especially hydrocarbons. The Nigerian economy is largely dependent on its oil sector which supplies 95% of its foreign earnings. While the exploitation and exploration of oil has created some fortune and contributed positively to the economic and technological advancement of Nigeria as a country, the accompanying socio-economic and ecological fallouts remain problematic. The public considers the oil producing companies operating in the Niger-Delta oil fields responsible as major environmental pollutants by way of relentless flaring and venting of gas in the environment, oil spillages, site clearing, deforestation and destruction of flora and fauna, and disturbances of the ecosystem in the70,000 square kilometers Niger-Delta wetland (Oguejifor, 1993).
ACID RAIN FORMATION
Acid rain is commonly used to describe the deposition of acidic components in rain, snow, fog, dew or dry particles. (Ufarana, 2004). The primary sources are sulphur dioxide, carbon dioxide and oxide of oxides of nitrogen. A variety of industrial processes, such as the production of iron and steel, utility factories, oil producing companies are responsible for the

emissions of obnoxious gases that resulted into acid rain. It has been reported that acid rain is one of the most discussed modes of environmental pollution in recent years (Odigure and Abdulkareem, 2003). Although, acid rain usually consists of relatively mild acids, they are sufficiently caustic to do great harm over time to certain natural ecosystems. Already there is much evidence that deposition of acid lead to lakes and stream acidification, stunted growth of flora while acid sensitive crops leads to lakes and stream acidification, stunted growth of flora while acid sensitive crops will die in affected areas (Abdulkareem, 2003). In cities, the corrosions of buildings and monuments are both exacerbated and accelerated (Odigure and Abdulkareem, 2004). To some extent acid rain has always been present in certain humid environment, originating from natural events as volcanic eruption, forest fires and even the
bacterial decomposition of dead organism (Odigure and Abdulkareem, 2001).

RESULT AND DISCUSSION:
The table 1. Indicates the Niger Delta Regions, land area and the population of which River state appears the largest (5,185,420). From the analysis of the oil spill in Niger Delta (table
2). The descriptive analysis indicates very high standard error of 4.39 x 104 in quantity spilled
(barrels), 5.148 x 103 in quantity recovered (barrels). Also the net volume lost to the environment indicates 3.907x104 (fig 1). Multiple bar chart on (table 2), indicates that quality spilled (barrels) over the years was highest. Fig2: trend analysis shows the equation
Y = 492x - 2061
and the correlation determination of (R2=0.131) which is low to the study.
Fig 3. ( Pie chart), indicates that Nigeria was the highest in the flaring of gas production in 2
Further, analysis was carried out using multiple regression analysis on table 4, where
Y = production
X1 = export in barrels
X2 = domestic consumption in (barrels). The model specification
y = B0 + B1X1 + B2 X2.
y = 8.984+1.036x1+0.880x2
The analysis of variance on the study indicates that there exist a significance difference on the crude oil production, export and domestic consumption (in barrels) in Niger Delta over the years of study. The residual indicates high and positive change of 0.956 (96%.). The standard error for production is very high (1955.910), std error for export (1102.165) and that of error for domestic consumption 925.898 respectively:

Analysis on (table 5) indicates the model:
x1 – utilization in barrels x2 – flares (m3)
y - production.
And there existed a significance difference in the study, and a high correlation determination (R2 = 0.943). The histogram (fig iv) shows the distribution production of crude oil, while (fig. v) represent the mean temperature during the study period.

SUMMARY/CONCLUSION
Environment pollution due to heat radiation from gas flaring stations in the Niger-Delta area of Nigeria has been identified as one of the major causes of strives, demonstration and sometimes- violent protest between the oil exploitation companies and habitants of Niger-Delta area of Nigeria. The result also clearly show that continuous gas flaring irrespective of the quality deposited in the immediate environment will in the long run lead to change in the physicochemical properties of environment due to the quantity of heat radiated, which influence the temperature change negatively. Gas flaring in Nigeria today possesses an environmental hazard to the nation at large. So much damage is being done to the environment through gas flaring, that if nothing is done in a few years from now, serious environmental and health problems such as lost of vegetation and diseases such as asthora, cancer, premature death, , etc will emerge. And as such lead to an increase in effective temperature of the earth. If gas flaring is not stopped or converted to a source of enormous revenue for the nation. The human race will be responsible for cooking the atmosphere to a point unbearable for man existence.
Finding solutions to these and other environmental problems isn’t always easy, and required agencies, environmental organizations, industry, Governments and the public, to work together to ensure environmental
safety . The department of Health work closely together with Government

agencies, the public and other who are concerned about environmental safety have to;
(1.) Provide consultation, trainings, and presentations of schools, local health agencies, regulated parties, and others regarding a variety of environmental safety issues.
(2.) Enforce the stop of burning off the associated gas (AG) which
has been illegal since 1984.
(3.) Conduct site-specific assessments of health risks from pollutants emitted by industries, hazardous waste sites, feedlots, and other pollution sources.
(4.) Evaluate the effects of pollution on vulnerable populations,
such as children and people with respiratory diseases so that risk assessment methods are adequately protective of human health.
(5.) Develop Health-Based Rules and Guidance for environmental used for site-specific assessments and environmental permit reviews.
(6.) Track research about the health effects of envionmental
pollutants on an ongoing basis, and incorporate new methods and data into health risk assessments and best practices guidelines.
(7.) Increase more Meteorological Agencies.
