摘要：Various fractions of hydrocarbon in water and sediments from Great Kwa River Estuary (GKRE) Southeast coast of Nigeria were studied quarterly for a period of one year by extracting the total hydrocarbons (THC) from samples. After pre treatment, finger prints of various hydrocarbon fractions were determined by (GC FID). Results analysis show that the sediments contain high level of hydrocarbon of crude petroleum origin, suggesting possible impact of petroleum industries in the area. Only 50% of hydrocarbon fraction from water was in sediment, confirming higher concentration in sediment than in water. The sediments contained wide range of parafinic and aromatic fraction. Their levels were generally higher than the standard recommended by the National Department of Petroleum (DPR) and Federal Environmental Protection Agency (FEPA). However, the Great Kwa River Estuary (GKRE) appeared only moderately contaminated with hydrocarbons but not polluted as at this study. Continuous monitoring was recommended for environmental quality of this marine environment in view of the offshore petroleum industries and the upstream municipal activities that discharge untreated waste into this marine ecosystem
