Assessment of the Impact of Flared Gas and Oil Spilled on Human Health and Environmental Degradation: Evidence from the Niger Delta Region, Nigeria. American Journal of Environmental Science and Engineering. Vol. 7, No. 1, 2023, pp. 5-16. doi: 10.11648/j.ajese.20230701.12 Received: January 20, 2023; Accepted: February 13, 2023; Published: March 15, 2023 Abstract: Flared gas produce emissions that have the potential to contribute to global warming and climate change. Oil spills destroy the aesthetic values of land and water sources such as drinking, recreation, fishing and farming. the discharge of these explorative activities results to challenge on human health and environmental ill-quality and degradation of the ecosystem. The objective of the study is to examine the impact of flared gas and oil spilled flaring on human health and environmental degradation in the Niger Delta region. Primary data were sourced from field surveys from the use of questionnaires administration while secondary data were sourced from documentary and established materials while. A total of 307 copies of questionnaires were designed and administered to the 15 selected communities a crossed the 6 states that constitute the region. Information from these data was got from two (2) sets of respondents. From this total number, 300 were administered to residents of the 15 selected communities while the remaining were administered to staff of the Commission, at 1 each per state headquarters and 1 copy administered in the office of the Ministry headquarters in River’s state. In each of these communities, a default number of 20 copies of questionnaires were distributed in the selected communities. The questionnaires were administered through systematic random sampling techniques Both the descriptive and inferential statistical techniques of 2-Way ANOVA were used for the study. The results showed that that the impact of flared gas and oil spilled on human health does not vary significantly on environmental degradation among the states of the Niger Delta region. The likely common ailments from a polluted environment for human health are that oil pollution generates air-borne diseases, like diphobia, chromatisa, delivum, heart attack, skin disease, dysentery, typhoid fever, asthma, pneumonia emphysema. Oil spills destroy the land’s aesthetic values and farmland pollution as well as the quality of water sources such as drinking, recreation, swimming, fishing, and domestic use. The study recommends that there should be justice for resource control and allocation. Places, where natural resources are exploited with major effects on the environment, biodiversity loss and threats to human health and safety should be adequately rewarded and compensated.

Introduction It has been estimated that Nigeria has over 120 trillion cubic feet of natural gas reserves currently flared and about 2 billion standard cubic meters of these gasses consist of methane and natural gas liquids such as ethane, propane, pentane and butane. Methane gas, if further treated can be used as feedstock for acetylene used in welding chemicals, ammonia can be used in fertilizer, plastics, and explosives,
