Phytostabilization potential of Saccharum spontaneum in chromium contaminated soil
Abstract
The Philippine archipelago is abundant in extractable metallic resources, which is being exported to other countries. But when global market prices of chromium go down, it is stockpiled temporarily. This study focused on metallophytes growing in a processing plant in Manticao, Misamis Oriental, which stockpiled ferrochromium for the past five years. Plant and associated soil samples in the area were collected, identified, and tested for the amount of Chromium (Cr). Among ten plant species found in the location of a ferrochromium stockpile, the grass commonly known as the wild sugarcane (Saccharum spontaneum) from the family Poaceae tolerated the high concentration of Chromium – a characteristic of a metallophyte better suited for phytostabilization. It contained 811.0 mg kg-1 Chromium in its below ground biomass, and was found to have potential use in a phytostabilization strategy for chromium contaminated soil.
