Phytoremediation is the plant based process to remove toxins such as heavy metals from the soil. In this experiment, we hypothesized Bermuda grass (Cyndon dactylon) will absorb a detectable level of zinc, a nontoxic metal, from the soil. We grew two separate groups of grass: the control and the experimental, which was watered with zinc acetate. Neither of the groups produced enough yield within the weeks given to the experiment, but if it went according to plan, we would have used flame atomic absorption spectroscopy to evaluate the relative concentrations of zinc. Significant uptake of zinc could reveal a possible use of bermuda grass to phytoextract other toxic heavy metals from the soil and reduce anthropogenic impact on the earth.
