My team is leading some experiments with high biomass producing crops for heavy metal phytoremediation from soils. Some cover crops such velvet bean and hyacinth bean are good for Pb and Cd phytoextraction.
My M Sc student working on Heavy metal Uptake by using specific species of Plants , Fungi to remove the pollution. my answer to your question is : Every pollution kind need specific species to remedite , and thats depending on concentrations of pollutants.
Thank you Dr. Fadhel for your kindly reply. Is there any method to clean air pollution? I could not find papers or projects about that. Do you have any experience or study on that subject?
NASA (US National Aeronautics and Space Administration) has studied plants for treating air and water. Here is an early publication https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19930073077.pdf. Much other research has followed, such as at Purdue University and via the Hazardous Substance Research Center. Here's a list to get you started https://cfpub.epa.gov/ncer_abstracts/index.cfm/fuseaction/display.publications/abstract/5852, and which should lead you to subsequent work by those and other researchers and in those and other publications.
Festuca, Brassicas... or grasses are usually good candidates for easily phytorremediation. Fast growth, wide ranges of soil pH and metal contamination...
