    The impact of gas flaring fallout on cassava flour dried around gas flaring sites in Delta State
    (Federal University of Technology, Owerri, 2015-12) Ikwuakolam, Innocent Maduabuchi
    This study investigated the impact of gas flaring fallout on cassava flour (Tapioca/kpokpo garri) dried around gas flaring sites in Delta State was undertaken. The test samples used for the analysis were obtained from a farm at Ogbe Avenue off PTI Road; Effurun. Three (3) samples A, B and C were obtained. Sample A was dried at PAN OCEAN flare site Oghara, while sample B was dried at AGIP flare site Kwale and sample C, which is the control was dried in an oven in the laboratory. The processed (dried) samples were analyzed for Nickel, Vanadium, zinc, arsenic, iron, copper and Carbon deposit, using Atomic Absorption Spectrophotometer (AAS) and Titrimetric Method. Nickel was 0.3ppm, zinc 0.001 ppm, arsenic 0.80ppm, copper 0.01ppm, iron 0.39ppm and that of vanadium was 0.03ppm; sample B, nickel was also 0.37ppm, zinc 0.001ppm, arsenic 0.9ppm, copper 0.02ppm, iron 0.29ppm and vanadium was 0.04ppm. However, that of carbon deposit had 6.85ppm in sample A and 8.32ppm in sample B. The Crowcon Gasman Air Monitor that had been pre-calibrated using air cylinder standard was used in the direct detection of oxides of sulphur, oxides nitrogen, volatile organic compounds and ozone (SOx, NOx, VOC and O3) 0.001, 0.01, 0.018, 03 respectively. In-situ test was used to measure the ambient air around the flaring stack. Hand-held Testrel 4500 weather Tracker, a high precision in-situ weather monitoring equipment was used in the determination of ambient temperature, wind speed and relative humidity. The study was carried out at the sampling points and the readings were obtained. It was noticed that all the samples analyzed were within the permissible limit. Though the analysed parameters were within permissible limits, constant monitoring should be done.
