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 (m HQ) 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...
