Six air samples were collected from six locations in Warri and Effurun environs and were analysed for Volatile Organic Compounds. (VOCs) After treatment of samples, VOCs were determined with Gas Chromatography coupled with Flame Ionization Detector (GC / FID). Results obtained showed concentrations of VOCs in the range of 0.42 – 28.78, 0.32 – 31.34, 0.29 – 31.61, 1.87 – 36.26, 0.20 – 37.23 and 0.45 – 33.56 ug/m3 for Effurun Roundabout, Warri Refinery, Effurun Market, Enerhen Junction, NPA and Ogunu with total VOCs of 177.8, 147.99, 179.13, 282.35, 196.65 and 168.93 ug/m3 respectively. Kruskal Wallis test revealed no significant difference across the studied locations. All the studied locations were found to be contaminated / slightly polluted by these gaseous components when values obtained were compared with critical values for Air Quality Guideline. It was therefore recommended that we as individuals must consider the consequences for our actions and work to improve air quality for future generations.
