Identify the types and levels of pollutants present in the dumpsite soil and water samples using appropriate analytical methods, such as atomic absorption spectroscopy, gas chromatography, or mass spectrometry
Select the plants that have been reported to have bioremediation capabilities for the pollutants of interest, such as sunflower, Indian mustard, vetiver grass, or poplar
Plant the selected plants in pots or plots containing the dumpsite soil and water samples, and maintain them under optimal conditions of irrigation, fertilization, and pest control
Monitor the growth and health of the plants, and measure the changes in the pollutant levels in the soil and water samples over time using the same analytical methods as before
Compare the results with those of control plants grown in unpolluted soil and water samples, and evaluate the bioremediation potentials of the selected plants based on the percentage of pollutant removal or reduction achieved by the plants
Marigold plant is a good plant for phytoremediation purpose, it can be grown in dumpsite. i have a publication on that u can go through (Interaction among Heavy Metals in Landfill Leachate and Their Effect on the Phytoremediation Process of Indian Marigold)
