New ecological risk indices for evaluating heavy metals contamination in aquatic sediment: A case study of the Gulf of Guinea
New indices – modified hazard quotient (mHQ) and ecological contamination index (ECI) – were developed for the evaluation of heavy metals contamination of sediment. Sequential extraction method was employed to determine the levels of cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), and lead (Pb) in subtidal sediment samples from tropical ecosystems off the Gulf of Guinea. The results...

Benson Nsikak » Nsikak Benson holds a Ph.D. degree in Marine Environmental Chemistry. His research interest is primarily on investigating the exchange of marine trace gases between the atmosphere and the ocean. He is interested in developing a quantitative understanding of the cycling of carbon, nutrients and other elements in ocean systems as well as interactions with ocean biology and anthropogenic impacts.... view full profile
