Description
The aim of this study was to evaluate the heavy metal content in soils and grasses planted on selected contaminated soils. The study was a 3 x 2 factorial experiment in a completely randomized design comprising of two factors which are: 3 soil sources (i.e., industrial site, dump site and Fadama (a lowland around a river/stream) which was used as the control) and 2 varieties of Megathyrsus maximus (var. Local and Ntchisi) replicated four times. Soils were collected from the three sites and planting was done in a greenhouse. Soil samples were collected before and after planting. Samples of the dried grasses were milled and analyzed for heavy metals (Cadmium, Chromium and Lead). The statistical evaluation was done by analysis of variance (ANOVA) and separation was by Tukey HSD on 0.05% probability values using SAS® 9.0 version. The results showed that Cadmium (Cd) accumulation was more in the soil than the plants. Megathyrsus maximus Local had higher (PMegathyrsus maximus (Local) had higher (PM. maximus have phytoextraction and phytostabilization potential and can be used for phytoremediation.
