Hydrobiological constraints of trace metals in surface water, coastal sediment and water lily of Calabar River, Nigeria

~ C2b382d2c81220222bf5e04aadccc25c.200x200
Trace metals concentrations in surface water, sediment and water lily (Nymphaea lotus) samples from the banks of Calabar River, a major tributary of Cross River Estuary, Nigeria were determined. The results revealed average concentrations 0.017, 0.010, 37.08 and 0.025 mg/l, respectively, for As, Cd, Fe and Pb in surface water samples, which exceeded Federal Environmental Protection Agency...

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
