Abstract

This study presents physicochemical characteristics (NO3-, SO42-, CO32-, suspended particulate matter, CO and pH) in air from Qua Iboe Estuary investigated as a result of the gas flare site located in Mkpanak, Ibeno in coastal area of Akwa Ibom State, Nigeria. Air and rainwater samples were collected during the dry and wet seasons in (2011-2012) and analyzed for the above physicochemical species using standard methods. Mean and standard deviation were used to assess the impact of these species in the region. Results obtained revealed that the mean concentrations of NO3- (44.77mg/m3 and 19.95 mg/m3) and SO42- (7.54 mg/m3 and 4.53 mg/m3) in dry and wet seasons were very low and were within the safety limits, suggesting minimal or no adverse effects on the environment. However, the mean concentrations of CO32-(2777.46 mg/m3 and 2859.69 mg/m3, CO(60.29 mg/m3 and 32.65 mg/m3) and pH (5.98 and 6.68) in dry and wet seasons respectively, were higher than the acceptable ambient air limits specified by the Federal Ministry of Environment (FMEnv) and Department of Petroleum Resources (DPR), Nigeria. Based on these findings, it can be concluded that within the studied region, the activity of constant gas flaring is one of the major sources of high concentration of these physicochemical species, with significant implications for the sustainability of the environment and life forms in this area. Recommendations are made to address these issues as best practices are presented.
