So some of you asked, what happens to the plants now that they're full of toxic metals? Well, I hope you're ready for some more phyto-words. Most of the time, the plants are harvested, incinerated, and replanted. Much easier than trying to sift through the soil for the pollutants. But sometimes, in cases of phytodegradation (AKA phytotransformation) the pollutants are broken down the by plant and used as nutrients, and require no further action by people. In phytovolatilization, the pollutant is absorbed by the plant, and a modified version of the contaminant transpires into the air in low concentrations.
