Estimation of the CO2 Level due to Gas Flaring in the Niger Delta
E.O. Nwaichi and M.A. Uzazobona

The level and distribution of CO2 and other associated potential contaminants at some flare sites in the Niger Delta were investigated to evaluate possible environmental characteristics. Two flowstations, Agbada 1 and 2 of Shell Petroleum Development Corporation were monitored while Eneka village with no history of gas flaring was introduced as control for comparison for a period of three months. At the Department of Petroleum Resources (DPR) recommended distance of 200 m away from flare stack, concentrations of contaminants were for CO 55 μg m-3, CO2 59.25 μg m-3, Ammonia 1 ppm, Particulates 0.8 μg m-3, sulphur dioxide 7.45 μg m-3 and nitrogen dioxide 16.3 μg m-3; Carbon monoxide 11.2 μg m-3, Carbon dioxide 69.05 μg m-3, Ammonia 1 ppm, Particulates 0.85 μg m-3, sulphur dioxide 24.2 μg m-3 and nitrogen dioxide 37.3 μg m-3; and Carbon monoxide 5.71 μg m-3, Carbon dioxide 5.54 μg m-3, Ammonia 1 ppm, Particulates 1.26 μg m-3, sulphur dioxide <0.01 μg m-3 and nitrogen dioxide <0.01 μg m-3 for Agbada 1 flowstation, Agbada 2 flowstation and Eneka village, respectively. The rainwater characteristics of the monitoring zones were also evaluated as core component of air quality and results gave acidic pH and significant bicarbonate levels showing CO2 emission activities. DPR and Federal Ministry of Environment set limits were also employed at assessment of flaring activities alongside the control study area. The findings suggest that the flaring activities at Agbada 1 and 2 flowstations significantly impacted on the environment via emissions and thus require mitigation measures to avert inherent biomagnifications with time.
