Nanoremediation technology holds enormous potential for the cleanup of hazardous pollutants. Here we report a study on the combined use of nano- and phytotechnology for the removal of chlorinated pesticides and heavy metals. The decomposition of endosulfan in the soil samples by nanophytoremediation was confirmed by gas chromatography followed by mass spectrometry. Of the different plants used in the presence of zero-valent iron nanoparticles (nZVI), A.calcarata was determined to have the best efficiency of removal and also found that the efficiency decreased in the order A. calcarata > O. sanctum > C. citratus. The nZVI endosulfan degradation mechanism appears to involve hydrogenolysis and sequential dehalogenation, which was confirmed by GC-MS analysis. Experiments were also conducted for the removal of Pb and Cd using Tradescantia spathacea (boat lily) and Alternanthera dentate. The analysis of heavy metals by ICP indicated that the plants with nZVI particles accumulated 73.7% Pb and 71.3% Cd.
