a)        Water pollution studies of  Calabar  River and Ibeno Coastline, Nigeria:

           Resume: Water quality surveys were conducted by monitoring physicochemical parameters, hydrocarbons and nutrient levels in the rivers.

b)        Marine Pollution studies of Nigerian beaches by tar balls

Resume: Monthly quantification of tar balls to assess the variation and the distribution of a tar along Ibeno and Okposo beaches.)

c)        Compositional Studies of  Crude oils  and oil residues from  offshore Nigerian coastline.

Resume: Chemical and Geochemical characteristics of oils and tar balls               from offshore zone of Bight of Bonny. The oils showed unimodal n-alkane distribution and low metal contents, while the tar balls exhibited a bimodal alkane distribution and had high metal contents

d)        Petroleum hydrocarbons in water and sediments from Cross River system , Nigeria.

           Resume: Low level of hydrocarbons are observed in the water column. Total

hydrocarbon in sediments showed a decreasing trend down the river (toward the estuary) in the Calabar river. High levels of THC above FEPA limit (10ppm).potential sources of hydrocarbons identified at the Cross river estuary.

e)        Water pollution  studies of Ibeno coast line , Qua Iboe river and mangrove ecosystem, Nigeria

Resume:: The levels of pollutant hydrocarbons (PAHs) has been determined. The seasonal variation in the water quality parameters have been obtained. There was exchange and distribution of hydrocarbon between surface water and interstitial water. The levels of heavy metals in Oysters and Bivalves along Ibeno coastline were assessed and compared to WHO limits.  Fe, Cu, and Zn were above  WHO limits while others were below.
