A Study of the Uptake of Heavy Metals by Plants near Metal ...

· The metal availability to plants depends on total concentration of metals in the soil and the forms in which they occur, pH, organic carbon, ionexchange capacity, stage of growth of plants, and microorganisms around the root zone [13, 14]. If these factors are constant, the uptake of a metal by different plant species may be compared.

the concentration of six heavy metals (Cd, Zu, Cu, Cr, Pb and Ni) in soil. Abstract Plant and soil samples were analyzed to determine the heavy metals (Cd, Zn, Cu, Cr, Pb and Ni) along major roads in Kwara State, Nigeria. Control plant and soil samples were obtained from Kwara State University (KWASU). Eight soil and plant samples were collected.

Plants can tolerate high heavy metals concentration from soil by two basic strategies (Baker, 1981). The first strategy is called accumulation strategy where metal can accumulate in plants at both high and low concentration from soil ( McGrath et al., 2001). These plants are capable of rendering the metals in various
