- Calendula officinalis removes cadmium

- Indian mustard (Brassica juncea & other Brassica species) has been shown to be
effective at accumulating high tissue concentrations of lead (do not eat!)
- Poplar trees remove contaminants present in groundwater which are then taken up and
transpired to the atmosphere, where they are degraded by sun. This mechanism is called
phytovolatilization, and is used for phytoremediation of VOCs (Volatile Organic Compounds)
- Phragmites australis removes heavy metals from waste water like cadmium and lead
- Vetiveria zizanoides - removes PAHs among many other pollutants from the soil
- Eucalyptus species removes hydrocarbons
- Eicchornia crassipes (water hyacinth) is well known as an invasive aquatic plant. It
is also used very effectively in phytoremediation for the removal of cyanide and
particularly for the rhizofiltration of effluents contaminated by heavy metals such as
copper, nickel, chromium and others.
- Melastoma malabathricum removes lead and arsenic
- Alyssum species are very effective in removing nickel
- Atriplex prostrata removes salt from saline soils

- Jatropha curcas is effective in removing mercury
- Chlorella vannielii is the only hyperaccumulator found to remove beryllium so far
- Euphorbia milii removes chromium from the soil and Trimethylamine and Formaldehyde
from the air. Breathing Trimethylamine can irritate the lungs causing coughing and/or
shortness of breath. Higher exposures can cause a build-up of fluid in the lungs
(pulmonary edema), a medical emergency, with severe shortness of breath
