Total Hydrocarbon (THC) of the Lower Kolo Creek in Otuogidi, Bayelsa State Nigeria

Abstract

Aquatic wild life and habitats are affected by pollution through physical contact, absorption and inhalation. This study was carried out to investigate the THC values of lower Kolo creek in Otuogidi Bayelsa State – Nigeria for 12 months. THC of sediment and water covering wet and dry season obtained from the creek were determined by the American standard test and methods (ASTMD3921). Data generated were statistically analysed by using analysis of variance (ANOVA) and T – test. Mean THC values in sediment was highest in kolo II (49.60mgKg^-1) and lowest in kolo III (15.15mgKg^-1). Highest THC values in water were recorded also in kolo II (58.05mg^-1) during the dry season. Mean THC values analyzed in water at all locations were higher than the statutory safe limit (7.8mg^-1). Result of this study shows that the lower kolo creek is polluted. The water and the sediment cannot support fishery or domestic purposes. It is expedient therefore to place the site under strict monitoring to prevent continuous entry of Effluents.
