A pre-study on the potential plants to treat heavy metals in contaminated soil

Heavy metals are among the most important sorts of contaminant in the environment.Several methods already used to clean up the environment from these kinds of contaminants,but most of them are costly and difficult to get optimum results.Currently,phytoremediation is an effective and affordable techn...
