ABSTRACT Climate Change affects the physiochemical quality of water, it directly affects the temperature of water and thus the concentration of metals and indirectly on the physical and chemical processes related to temperature in the water column changes. This affects the rate of biochemical processes with a significant decrease in oxygen concentration and the composition and distribution metals in water and sediment. The concentrations of heavy metals in water and sediment of Ekpan Creek was investigated from December, 2008 to May, 2009 at monthly interval. Five stations were designated along the water course for water and sediment collection. A varian Techtron Spectr AA – 10 Atomic Absorption Spectrophotometer with a printer attached was used for the determination of phosphate, sulphate, nitrate, copper, iron, chromium, manganese, lead, zinc and cadmium. At the stations, air temperature ranged from 280C to 320C, water temperature ranged between 280C and 32.50C; TDS, 463 to 503mg/L; DO, 4.12 to 7.44 mg/L; hardness, 85.47 to 125 mg/L; phosphate, in water(0.03 to 0.18 mg/L) sediment, 17.85 to 2484 mg/L); nitrate, in water 0.02 to 0.04 mg/L, sediment 1.47 to 9.51 mg/L; sulphate, in water 19.26 to 50.66 mg/L, sediment 1.47 to 9.51 mg/L; Iron, in water 0.65 to 0.43 mg/L, sediment 380.37 to 239.17 mg/L; zinc, in water 0.32 to 0.13 mg/L, sediment 8.11 to 3.14 mg/L; copper, in water 0.0038 to 0.0014 mg/L, sediment 1.33 to 0.05 mg/L; lead, in water 0.0042 to 0.001 mg/L; sediment 0.16 to 0.02 mg/L; cadmium, in water 0.028 to 0.001 mg/L, 0.504 to 0.019 mg/L; chromium, in water 0.0038 to 0.0012 mg/L, sediment 0.801 to 0.001 mg/L; manganese 2.44 to 0.86 mg/L. Statistical analysis of eighteen (18) physicochemical parameters was conducted using Excel and SPSS to check for significance (two way anova) were computed. The result showed that, rainfall followed a seasonal pattern of being higher in the rainy season than the dry season. The concentrations of heavy metals were also observed to be higher in sediment than in water which is expected from the impacts of climate change due to temperature increase. Generally, the concentrations of individual metals in water were within the WHO limits for water except iron that recorded a value of 1.032 mg/L at station III in January 2009.   Brief Biography of Elohor Freeman OLUOWO Mr. Elohor Freeman OLUOWO is presently enrolled in Nha Trang University, Nha Trang Vietnam studying Marine Based Ecosystem Management and Climate change under the NORAD sponsored programme. He is a fine researcher in Ecology majoring in water quality assessment, pollution studies, ecotoxicology and climate change. The Centre Coordinator, Centre for Environment and Sustainable Livelihood Projects (CESLP), Delta State, Nigeria (Non-Governmental Organization based in Nigeria). He holds a Master’s Degree in Environmental Quality Management and Pollution Management from University of Benin, Benin City, Nigeria. And a Bachelor’s (B.Sc) degree in General Microbiology from Ambrose Alli University, Ekpoma, Nigeria, Delta State. He loves researches expecially those that concerns baseline studies and biodiversity. He is inclined to environment and conservation education, for that reason advocating attitudinal change towards environmental management by developing future leaders by catching them young in management through programs and activities in the Niger Delta Nigeria. He has established several environmental clubs, especially in high schools across states in Nigeria. He looks towards the future for Africa capacity in water management (ocean and inland waters), climate change mitigation and Adaptation and general pollution management. Has somewhat experience working as an environmental consultant and research person in this area but with broad interest in environmental management.
