Residents of Finima community, Bonny Island, in Nigeria’s Niger Delta Region, for so many years now, have been exposed to the hazardous environmental conditions occasioned by the operations of oil and gas industry. And typical of this, is gas flaring. The flared gases as by-products of incomplete combustion are known to overwhelm the environment with numerous dangerous pollutants. Ultimately, the contamination of man’s food and water sources by these pollutants may trigger several severe health effects. The kidneys and the liver, by their natures are primarily endangered by most external pollutants. Considering the reports and realities on ground of the impact of long-term exposure to flared gases on both humans and the environment, it became imperative to embark on an in depth study based on established biomarkers to underscore the influence of exposure to flared gases on the renal functions of adults resident in Finima, Bonny Island. The individuals recruited as test subjects were those who have resided in this gas flare impacted environment for up to fifteen years and above. The values of this set of subjects were compared to control subjects drawn from non-oil and gas production environments. The subjects (400) were matched for age and sex, and sorted into exposed group (200) and control group (200). Blood samples were obtained from the subjects and analysed for serum levels of sodium, potassium, chloride, urea, creatinine and cystatin-C. The results revealed that individuals exposed to gas flare impacted environment had significantly (p<0.05) higher serum levels of cystatin-C, creatinine, urea, potassium, sodium and chloride with respect to the values of control subjects. The above results suggest that a long time exposure to low level of gas flare may lead to significant elevations of dysfunctional biomarkers of the kidneys and thus, may be predisposed to having renal derangements.
