摘要

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