Abstract :

This study was carried out to investigate the potentials of Commelina erecta and triton X-100 in remediating glyphosate polluted soil. Humus soil sample was collected from a vegetable garden in Alakahia community in Rivers State, Nigeria and was subsequently divided into different treatment groups I-VI each containing 2 kilograms of the soil sample mixed with 50ml of glyphosate in a polypropylene bag. The different treatment groups were incubated at 28-30 oC for 60 days and thereafter analysed for pH, conductivity, heavy metals, mineral elements, organic ions, total organic carbon (TOC) and nitrogen (TON) contents of the soil. The least pH value (7.01) was recorded in group III while the highest conductivity value (4173.33µs/cm) was observed in group IV. Copper, nickel and cadmium levels in all the amended groups were reduced when compared with the control. Generally, the mineral levels were increased in the amended groups when compared with the control. The TOC and TON contents of the amended soil did not exhibit significant difference when compared with the control except for group IV.
