Abstract

Presently, heavy metal pollution of our cultivable agricultural farmlands is increasing and is often associated with anthropogenic sources. Wetlands contaminated with detectable levels of metal toxicants and other trace macro-elements are frequently used for growing vegetable crops. To assess the impact of floodwater on soil of floodplain wetland of Cross River, soil samples were taken from uppermost 0-30 ern within designated thirty square grids and analytical determinations of cobalt (Co), lead (Pb ), manganese (Mn), nickel (Ni), vanadilllll (V) and copper (Cu) were carried out. The results show high accillllulat:ion of Mn (40.22±2.79 Mg g-'), Pb (22.47±0.58 Mg g-'), Cu (16.17±7.93 Mg g-') and Ni (17.24±4.12 Mg g-') from the wetland. The exploratory data analyses for each of the heavy metals revealed that the concentrations of the metals in the floodplain ultisols were more effectively influenced by environmental and anthropogenic attributes.
